Subject: gpu: host1x: Make host1x_context_device_bus_type constant

Since commit d492cc2573a0 ("driver core: device.h: make struct
bus_type a const *"), the driver core can properly handle constant
struct bus_type, move the host1x_context_device_bus_type variable
to be a constant structure as well, placing it into read-only memory
which can not be modified at runtime.

Subject: drm/panfrost: Add SYSTEM_TIMESTAMP and SYSTEM_TIMESTAMP_FREQUENCY
 parameters

Expose system timestamp and frequency supported by the GPU.

Mali uses an external timer as GPU system time. On ARM, this is wired to
the generic arch timer so we wire cntfrq_el0 as device frequency.

This new uAPI will be used in Mesa to implement timestamp queries and
VK_KHR_calibrated_timestamps.

v2:
- Rewrote to use GPU timestamp register
- Add missing include for arch_timer_get_cntfrq
- Rework commit message

v3:
- Move panfrost_cycle_counter_get and panfrost_cycle_counter_put to
  panfrost_ioctl_query_timestamp
- Handle possible overflow in panfrost_timestamp_read

Subject: drm/panfrost: Add cycle counter job requirement

Extend the uAPI with a new job requirement flag for cycle
counters. This requirement is used by userland to indicate that a job
requires cycle counters or system timestamp to be propagated. (for use
with write value timestamp jobs)

We cannot enable cycle counters unconditionally as this would result in
an increase of GPU power consumption. As a result, they should be left
off unless required by the application.

If a job requires cycle counters or system timestamps propagation, we
must enable cycle counting before issuing a job and disable it right
after the job completes.

Since this extends the uAPI and because userland needs a way to advertise
features like VK_KHR_shader_clock conditionally, we bumps the driver
minor version.

v2:
- Rework commit message
- Squash uAPI changes and implementation in this commit
- Simplify changes based on Steven Price comments

v3:
- Add Steven Price r-b
- Fix a codestyle issue

Subject: drm/imx: add internal bridge handling display-timings DT node

i.MX DRM DT bindings allow using either a proper panel / bridge graph to
provide information about connected panels, or just a display-timings DT
node, describing just the timings and the flags. Add helper bridge
driver supporting the latter usecase. It will be used by both LDB and
parallel-display drivers.

From a778028cc575deeb5224cc798de6e03d37331bca Mon Sep 17 00:00:00 2001

Subject: drm/panthor: Add DEV_QUERY_TIMESTAMP_INFO dev query

Expose timestamp information supported by the GPU with a new device
query.

Mali uses an external timer as GPU system time. On ARM, this is wired to
the generic arch timer so we wire cntfrq_el0 as device frequency.

This new uAPI will be used in Mesa to implement timestamp queries and
VK_KHR_calibrated_timestamps.

Since this extends the uAPI and because userland needs a way to advertise
those features conditionally, this also bumps the driver minor version.

v2:
- Rewrote to use GPU timestamp register
- Added timestamp_offset to drm_panthor_timestamp_info
- Add missing include for arch_timer_get_cntfrq
- Rework commit message

v3:
- Add panthor_gpu_read_64bit_counter
- Change panthor_gpu_read_timestamp to use
  panthor_gpu_read_64bit_counter

v4:
- Fix multiple typos in uAPI documentation
- Mention behavior when the timestamp frequency is unknown
- Use u64 instead of unsigned long long
  for panthor_gpu_read_timestamp
- Apply r-b from Mihail

Subject: drm/i915/pciids: use designated initializers in INTEL_VGA_DEVICE()

With IGT no longer using INTEL_VGA_DEVICE(), we can make it kernel
specific and use designated initializers. Ditto for
INTEL_QUANTA_VGA_DEVICE(). Remove the superfluous comments while at it.

Avoid including PCI IDs for one platform to the PCI IDs of another. It's

Subject: drm/sched: add optional errno to drm_sched_start()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The current implementation of drm_sched_start uses a hardcoded
-ECANCELED to dispose of a job when the parent/hw fence is NULL.
This results in drm_sched_job_done being called with -ECANCELED for
each job with a NULL parent in the pending list, making it difficult
to distinguish between recovery methods, whether a queue reset or a
full GPU reset was used.

To improve this, we first try a soft recovery for timeout jobs and
use the error code -ENODATA. If soft recovery fails, we proceed with
a queue reset, where the error code remains -ENODATA for the job.
Finally, for a full GPU reset, we use error codes -ECANCELED or
-ETIME. This patch adds an error code parameter to drm_sched_start,
allowing us to differentiate between queue reset and GPU reset
failures. This enables user mode and test applications to validate
the expected correctness of the requested operation. After a
successful queue reset, the only way to continue normal operation is
to call drm_sched_job_done with the specific error code -ENODATA.

v1: Initial implementation by Jesse utilized amdgpu_device_lock_reset_domain
    and amdgpu_device_unlock_reset_domain to allow user mode to track
    the queue reset status and distinguish between queue reset and
    GPU reset.
v2: Christian suggested using the error codes -ENODATA for queue reset
    and -ECANCELED or -ETIME for GPU reset, returned to
    amdgpu_cs_wait_ioctl.
v3: To meet the requirements, we introduce a new function
    drm_sched_start_ex with an additional parameter to set
    dma_fence_set_error, allowing us to handle the specific error
    codes appropriately and dispose of bad jobs with the selected
    error code depending on whether it was a queue reset or GPU reset.
v4: Alex suggested using a new name, drm_sched_start_with_recovery_error,
    which more accurately describes the function's purpose.
    Additionally, it was recommended to add documentation details
    about the new method.
v5: Fixed declaration of new function drm_sched_start_with_recovery_error.(Alex)
v6 (chk): rebase on upstream changes, cleanup the commit message,
          drop the new function again and update all callers,
          apply the errno also to scheduler fences with hw fences
v7 (chk): rebased

The dma_fence_set_error() function allows to set an error code on a
dma_fence object before it is signaled.

Document some of the potential error codes drivers should use and
especially what they mean.

Subject: drm/panic: Fix uninitialized spinlock acquisition with

It turns out that if you happen to have a kernel config where
CONFIG_DRM_PANIC is disabled and spinlock debugging is enabled, along with
KMS being enabled - we'll end up trying to acquire an uninitialized
spin_lock with drm_panic_lock() when we try to do a commit:

  rvkms rvkms.0: [drm:drm_atomic_commit] committing 0000000068d2ade1
  INFO: trying to register non-static key.
  The code is fine but needs lockdep annotation, or maybe
  you didn't initialize this object before use?
  turning off the locking correctness validator.

Fix this by stubbing these macros out when this config option isn't
enabled, along with fixing the unused variable warning that introduces.

From b8469721034300bbb6dec5b4bf32492c95e16a0c Mon Sep 17 00:00:00 2001
From: Eyal Birger <eyal.birger@gmail.com>

Subject: xfrm: respect ip protocols rules criteria when performing dst lookups

The series in the "fixes" tag added the ability to consider L4 attributes
in routing rules.

The dst lookup on the outer packet of encapsulated traffic in the xfrm
code was not adapted to this change, thus routing behavior that relies
on L4 information is not respected.

Pass the ip protocol information when performing dst lookups.

Subject: drm/sched: Fix dynamic job-flow control race

Fixes a race condition reported here: https://github.com/AsahiLinux/linux/issues/309#issuecomment-2238968609

The whole premise of lockless access to a single-producer-single-
consumer queue is that there is just a single producer and single
consumer.  That means we can't call drm_sched_can_queue() (which is
about queueing more work to the hw, not to the spsc queue) from
anywhere other than the consumer (wq).

This call in the producer is just an optimization to avoid scheduling
the consuming worker if it cannot yet queue more work to the hw.  It
is safe to drop this optimization to avoid the race condition.

Subject: drm/connector: hdmi: Fix writing Dynamic Range Mastering infoframes

The largest infoframe we create is the DRM (Dynamic Range Mastering)
infoframe which is 26 bytes + a 4 byte header, for a total of 30
bytes.

With HDMI_MAX_INFOFRAME_SIZE set to 29 bytes, as it is now, we
allocate too little space to pack a DRM infoframe in
write_device_infoframe(), leading to an ENOSPC return from
hdmi_infoframe_pack(), and never calling the connector's
write_infoframe() vfunc.

Instead of having HDMI_MAX_INFOFRAME_SIZE defined in two places,
replace HDMI_MAX_INFOFRAME_SIZE with HDMI_INFOFRAME_SIZE(MAX) and make
MAX 27 bytes - which is defined by the HDMI specification to be the
largest infoframe payload.

Fixes: f378b77227bc ("drm/connector: hdmi: Add Infoframes generation")
Fixes: c602e4959a0c ("drm/connector: hdmi: Create Infoframe DebugFS entries")

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For some applications, such as applications that uses huge pages, we might
want to have a different mountpoint, for which we pass mount flags that
better match our usecase.

Therefore, create a new function `drm_gem_object_init_with_mnt()` that
allow us to define the tmpfs mountpoint where the GEM object will be
created. If this parameter is NULL, then we fallback to `shmem_file_setup()`.

Subject: drm/gem: Create shmem GEM object in a given mountpoint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Create a function `drm_gem_shmem_create_with_mnt()`, similar to
`drm_gem_shmem_create()`, that has a mountpoint as a argument. This
function will create a shmem GEM object in a given tmpfs mountpoint.

This function will be useful for drivers that have a special mountpoint
with flags enabled.

Subject: drm/panthor: Add DEV_QUERY_GROUP_PRIORITIES_INFO dev query

Expose allowed group priorities with a new device query.

This new uAPI will be used in Mesa to properly report what priorities a
user can use for EGL_IMG_context_priority.

Since this extends the uAPI and because userland needs a way to
advertise priorities accordingly, this also bumps the driver minor
version.

v2:
- Remove drm_panthor_group_allow_priority_flags definition
- Document that allowed_mask is a bitmask of drm_panthor_group_priority

v3:
- Use BIT macro in panthor_query_group_priorities_info
- Add r-b from Steven Price and Boris Brezillon

Subject: drm/fbdev-helper: Move color-mode lookup into 4CC format helper

The color mode as specified on the kernel command line gives the user's
preferred color depth and number of bits per pixel. Move the
color-mode-to-format conversion from fbdev helpers into a 4CC helper,
so that it can be shared among DRM clients.

v2:
- fix grammar in commit message (Laurent)

Subject: drm/fbdev: Add memory-agnostic fbdev client

Add an fbdev client that can work with any memory manager. The
client implementation is the same as existing code in fbdev-dma or
fbdev-shmem.

Provide struct drm_driver.fbdev_probe for the new client to allocate
the surface GEM buffer. The new callback replaces fb_probe of struct
drm_fb_helper_funcs, which does the same.

To use the new client, DRM drivers set fbdev_probe in their struct
drm_driver instance and call drm_fbdev_client_setup(). Probing and
creating the fbdev surface buffer is now independent from the other
operations in struct drm_fb_helper. For the pixel format, the fbdev
client either uses a specified format, the value in preferred_depth
or 32-bit RGB.

v2:
- test for struct drm_fb_helper.funcs for NULL (Sui)
- respect struct drm_mode_config.preferred_depth for default format

Subject: drm: Add client-agnostic setup helper

DRM may support multiple in-kernel clients that run as soon as a DRM
driver has been registered. To select the client(s) in a single place,
introduce drm_client_setup().

Drivers that call the new helper automatically instantiate the kernel's
configured default clients. Only fbdev emulation is currently supported.
Later versions can add support for DRM-based logging, a boot logo or even
a console.

Some drivers handle the color mode for clients internally. Provide the
helper drm_client_setup_with_color_mode() for them.

Using the new interface requires the driver to select
DRM_CLIENT_SELECTION in its Kconfig. For now this only enables the
client-setup helpers if the fbdev client has been configured by the
user. A future patchset will further modularize client support and
rework DRM_CLIENT_SELECTION to select the correct dependencies for
all its clients.

v5:
- add CONFIG_DRM_CLIENT_SELECTION und DRM_CLIENT_SETUP
v4:
- fix docs for drm_client_setup_with_fourcc() (Geert)
v3:
- fix build error
v2:
- add drm_client_setup_with_fourcc() (Laurent)
- push default-format handling into actual clients

Subject: drm/fbdev-dma: Remove obsolete setup function

The old setup function drm_fbdev_dma_setup() is unused. Remove it and
its internal callbacks. New drivers should call drm_client_setup()
instead.

Subject: drm/fbdev-ttm: Support struct drm_driver.fbdev_probe

Rework fbdev probing to support fbdev_probe in struct drm_driver
and reimplement the old fb_probe callback on top of it. Provide an
initializer macro for struct drm_driver that sets the callback
according to the kernel configuration.

This change allows the common fbdev client to run on top of TTM-
based DRM drivers.

Subject: close_range(): fix the logics in descriptor table trimming

Cloning a descriptor table picks the size that would cover all currently
opened files.  That's fine for clone() and unshare(), but for close_range()
there's an additional twist - we clone before we close, and it would be
a shame to have
	close_range(3, ~0U, CLOSE_RANGE_UNSHARE)
leave us with a huge descriptor table when we are not going to keep
anything past stderr, just because some large file descriptor used to
be open before our call has taken it out.

Unfortunately, it had been dealt with in an inherently racy way -
sane_fdtable_size() gets a "don't copy anything past that" argument
(passed via unshare_fd() and dup_fd()), close_range() decides how much
should be trimmed and passes that to unshare_fd().

The problem is, a range that used to extend to the end of descriptor
table back when close_range() had looked at it might very well have stuff
grown after it by the time dup_fd() has allocated a new files_struct
and started to figure out the capacity of fdtable to be attached to that.

That leads to interesting pathological cases; at the very least it's a
QoI issue, since unshare(CLONE_FILES) is atomic in a sense that it takes
a snapshot of descriptor table one might have observed at some point.
Since CLOSE_RANGE_UNSHARE close_range() is supposed to be a combination
of unshare(CLONE_FILES) with plain close_range(), ending up with a
weird state that would never occur with unshare(2) is confusing, to put
it mildly.

It's not hard to get rid of - all it takes is passing both ends of the
range down to sane_fdtable_size().  There we are under ->files_lock,
so the race is trivially avoided.

So we do the following:
	* switch close_files() from calling unshare_fd() to calling
dup_fd().
	* undo the calling convention change done to unshare_fd() in
60997c3d45d9 "close_range: add CLOSE_RANGE_UNSHARE"
	* introduce struct fd_range, pass a pointer to that to dup_fd()
and sane_fdtable_size() instead of "trim everything past that point"
they are currently getting.  NULL means "we are not going to be punching
any holes"; NR_OPEN_MAX is gone.
	* make sane_fdtable_size() use find_last_bit() instead of
open-coding it; it's easier to follow that way.
	* while we are at it, have dup_fd() report errors by returning
ERR_PTR(), no need to use a separate int *errorp argument.

+
+
+Overview
+========
+
+The folio_queue struct forms a single segment in a segmented list of folios
+that can be used to form an I/O buffer.  As such, the list can be iterated over
+using the ITER_FOLIOQ iov_iter type.
+
+The publicly accessible members of the structure are::
+
+	struct folio_queue {
+		struct folio_queue *next;
+		struct folio_queue *prev;
+		...
+	};
+
+A pair of pointers are provided, ``next`` and ``prev``, that point to the
+segments on either side of the segment being accessed.  Whilst this is a
+doubly-linked list, it is intentionally not a circular list; the outward
+sibling pointers in terminal segments should be NULL.
+
+Each segment in the list also stores:
+
+ * an ordered sequence of folio pointers,
+ * the size of each folio and
+ * three 1-bit marks per folio,
+
+but hese should not be accessed directly as the underlying data structure may
+change, but rather the access functions outlined below should be used.
+
+The facility can be made accessible by::
+
+	#include <linux/folio_queue.h>
+
+and to use the iterator::
+
+	#include <linux/uio.h>
+
+
+Initialisation
+==============
+
+A segment should be initialised by calling::
+
+	void folioq_init(struct folio_queue *folioq);
+
+with a pointer to the segment to be initialised.  Note that this will not
+necessarily initialise all the folio pointers, so care must be taken to check
+the number of folios added.
+
+
+Adding and removing folios
+==========================
+
+Folios can be set in the next unused slot in a segment struct by calling one
+of::
+
+	unsigned int folioq_append(struct folio_queue *folioq,
+				   struct folio *folio);
+
+	unsigned int folioq_append_mark(struct folio_queue *folioq,
+					struct folio *folio);
+
+Both functions update the stored folio count, store the folio and note its
+size.  The second function also sets the first mark for the folio added.  Both
+functions return the number of the slot used.  [!] Note that no attempt is made
+to check that the capacity wasn't overrun and the list will not be extended
+automatically.
+
+A folio can be excised by calling::
+
+	void folioq_clear(struct folio_queue *folioq, unsigned int slot);
+
+This clears the slot in the array and also clears all the marks for that folio,
+but doesn't change the folio count - so future accesses of that slot must check
+if the slot is occupied.
+
+
+Querying information about a folio
+==================================
+
+Information about the folio in a particular slot may be queried by the
+following function::
+
+	struct folio *folioq_folio(const struct folio_queue *folioq,
+				   unsigned int slot);
+
+If a folio has not yet been set in that slot, this may yield an undefined
+pointer.  The size of the folio in a slot may be queried with either of::
+
+	unsigned int folioq_folio_order(const struct folio_queue *folioq,
+					unsigned int slot);
+
+	size_t folioq_folio_size(const struct folio_queue *folioq,
+				 unsigned int slot);
+
+The first function returns the size as an order and the second as a number of
+bytes.
+
+
+Querying information about a folio_queue
+========================================
+
+Information may be retrieved about a particular segment with the following
+functions::
+
+	unsigned int folioq_nr_slots(const struct folio_queue *folioq);
+
+	unsigned int folioq_count(struct folio_queue *folioq);
+
+	bool folioq_full(struct folio_queue *folioq);
+
+The first function returns the maximum capacity of a segment.  It must not be
+assumed that this won't vary between segments.  The second returns the number
+of folios added to a segments and the third is a shorthand to indicate if the
+segment has been filled to capacity.
+
+Not that the count and fullness are not affected by clearing folios from the
+segment.  These are more about indicating how many slots in the array have been
+initialised, and it assumed that slots won't get reused, but rather the segment
+will get discarded as the queue is consumed.
+
+
+Folio marks
+===========
+
+Folios within a queue can also have marks assigned to them.  These marks can be
+used to note information such as if a folio needs folio_put() calling upon it.
+There are three marks available to be set for each folio.
+
+The marks can be set by::
+
+	void folioq_mark(struct folio_queue *folioq, unsigned int slot);
+	void folioq_mark2(struct folio_queue *folioq, unsigned int slot);
+	void folioq_mark3(struct folio_queue *folioq, unsigned int slot);
+
+Cleared by::
+
+	void folioq_unmark(struct folio_queue *folioq, unsigned int slot);
+	void folioq_unmark2(struct folio_queue *folioq, unsigned int slot);
+	void folioq_unmark3(struct folio_queue *folioq, unsigned int slot);
+
+And the marks can be queried by::
+
+	bool folioq_is_marked(const struct folio_queue *folioq, unsigned int slot);
+	bool folioq_is_marked2(const struct folio_queue *folioq, unsigned int slot);
+	bool folioq_is_marked3(const struct folio_queue *folioq, unsigned int slot);
+
+The marks can be used for any purpose and are not interpreted by this API.
+
+
+Folio queue iteration
+=====================
+
+A list of segments may be iterated over using the I/O iterator facility using
+an ``iov_iter`` iterator of ``ITER_FOLIOQ`` type.  The iterator may be
+initialised with::
+
+	void iov_iter_folio_queue(struct iov_iter *i, unsigned int direction,
+				  const struct folio_queue *folioq,
+				  unsigned int first_slot, unsigned int offset,
+				  size_t count);
+
+This may be told to start at a particular segment, slot and offset within a
+queue.  The iov iterator functions will follow the next pointers when advancing
+and prev pointers when reverting when needed.
+
+
+Lockless simultaneous production/consumption issues
+===================================================
+
+If properly managed, the list can be extended by the producer at the head end
+and shortened by the consumer at the tail end simultaneously without the need
+to take locks.  The ITER_FOLIOQ iterator inserts appropriate barriers to aid
+with this.
+
+Care must be taken when simultaneously producing and consuming a list.  If the
+last segment is reached and the folios it refers to are entirely consumed by
+the IOV iterators, an iov_iter struct will be left pointing to the last segment
+with a slot number equal to the capacity of that segment.  The iterator will
+try to continue on from this if there's another segment available when it is
+used again, but care must be taken lest the segment got removed and freed by
+the consumer before the iterator was advanced.
+
+It is recommended that the queue always contain at least one segment, even if
+that segment has never been filled or is entirely spent.  This prevents the
+head and tail pointers from collapsing.

Subject: net: Add netif_get_gro_max_size helper for GRO

Add a small netif_get_gro_max_size() helper which returns the maximum IPv4
or IPv6 GRO size of the netdevice.

We later add a netif_get_gso_max_size() equivalent as well for GSO, so that
these helpers can be used consistently instead of open-coded checks.

Subject: net: Fix gso_features_check to check for both
 dev->gso_{ipv4_,}max_size

Commit 24ab059d2ebd ("net: check dev->gso_max_size in gso_features_check()")
added a dev->gso_max_size test to gso_features_check() in order to fall
back to GSO when needed.

This was added as it was noticed that some drivers could misbehave if TSO
packets get too big. However, the check doesn't respect dev->gso_ipv4_max_size
limit. For instance, a device could be configured with BIG TCP for IPv4,
but not IPv6.

Therefore, add a netif_get_gso_max_size() equivalent to netif_get_gro_max_size()
and use the helper to respect both limits before falling back to GSO engine.

Subject: btrfs: tracepoints: end assignment with semicolon at
 btrfs_qgroup_extent event class

While running checkpatch.pl against a patch that modifies the
btrfs_qgroup_extent event class, it complained about using a comma instead
of a semicolon:

  $ ./scripts/checkpatch.pl qgroups/0003-btrfs-qgroups-remove-bytenr-field-from-struct-btrfs_.patch
  WARNING: Possible comma where semicolon could be used
  #215: FILE: include/trace/events/btrfs.h:1720:
  +		__entry->bytenr		= bytenr,
		__entry->num_bytes	= rec->num_bytes;

  total: 0 errors, 1 warnings, 184 lines checked

So replace the comma with a semicolon to silence checkpatch and possibly
other tools. It also makes the code consistent with the rest.

In the parse_perf_domain function, if the call to
of_parse_phandle_with_args returns an error, then the reference to the
CPU device node that was acquired at the start of the function would not
be properly decremented.

Address this by declaring the variable with the __free(device_node)
cleanup attribute.

Subject: bpf: Make sure internal and UAPI bpf_redirect flags don't overlap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The bpf_redirect_info is shared between the SKB and XDP redirect paths,
and the two paths use the same numeric flag values in the ri->flags
field (specifically, BPF_F_BROADCAST == BPF_F_NEXTHOP). This means that
if skb bpf_redirect_neigh() is used with a non-NULL params argument and,
subsequently, an XDP redirect is performed using the same
bpf_redirect_info struct, the XDP path will get confused and end up
crashing, which syzbot managed to trigger.

With the stack-allocated bpf_redirect_info, the structure is no longer
shared between the SKB and XDP paths, so the crash doesn't happen
anymore. However, different code paths using identically-numbered flag
values in the same struct field still seems like a bit of a mess, so
this patch cleans that up by moving the flag definitions together and
redefining the three flags in BPF_F_REDIRECT_INTERNAL to not overlap
with the flags used for XDP. It also adds a BUILD_BUG_ON() check to make
sure the overlap is not re-introduced by mistake.

Fixes: e624d4ed4aa8 ("xdp: Extend xdp_redirect_map with broadcast support")

Subject: ALSA: hda: fix trigger_tstamp_latched

When the trigger_tstamp_latched flag is set, the PCM core code assumes that
the low-level driver handles the trigger timestamping itself. Ensure that
runtime->trigger_tstamp is always updated.

[Analysis]
The problem is that inotify_new_watch() is using GFP_KERNEL to allocate
new watches under group->mark_mutex, however if dentry reclaim races
with unlinking of an inode, it can end up dropping the last dentry reference
for an unlinked inode resulting in removal of fsnotify mark from reclaim
context which wants to acquire group->mark_mutex as well.

This scenario shows that all notification groups are in principle prone
to this kind of a deadlock (previously, we considered only fanotify and
dnotify to be problematic for other reasons) so make sure all
allocations under group->mark_mutex happen with GFP_NOFS.

Subject: net: test for not too small csum_start in virtio_net_hdr_to_skb()

syzbot was able to trigger this warning [1], after injecting a
malicious packet through af_packet, setting skb->csum_start and thus
the transport header to an incorrect value.

We can at least make sure the transport header is after
the end of the network header (with a estimated minimal size).

Subject: NFSv4: Prevent NULL-pointer dereference in nfs42_complete_copies()

On the node of an NFS client, some files saved in the mountpoint of the
NFS server were copied to another location of the same NFS server.
Accidentally, the nfs42_complete_copies() got a NULL-pointer dereference
crash with the following syslog:

Analysing the vmcore, we know that nfs4_copy_state listed by destination
nfs_server->ss_copies was added by the field copies in handle_async_copy(),
and we found a waiting copy process with the stack as:
PID: 3511963  TASK: ffff710028b47e00  CPU: 0   COMMAND: "cp"

 #9 [ffff8001116efc50] __nfs4_copy_file_range.constprop.0 at ffff8000054ed694 [nfsv4]

The NULL-pointer dereference was due to nfs42_complete_copies() listed
the nfs_server->ss_copies by the field ss_copies of nfs4_copy_state.
So the nfs4_copy_state address ffff0100f98fa3f0 was offset by 0x10 and
the data accessed through this pointer was also incorrect. Generally,
the ordered list nfs4_state_owner->so_states indicate open(O_RDWR) or
open(O_WRITE) states are reclaimed firstly by nfs4_reclaim_open_state().
When destination state reclaim is failed with NFS_STATE_RECOVERY_FAILED
and copies are not deleted in nfs_server->ss_copies, the source state
may be passed to the nfs42_complete_copies() process earlier, resulting
in this crash scene finally. To solve this issue, we add a list_head
nfs_server->ss_src_copies for a server-to-server copy specially.

Subject: nfs_common: fix race in NFS calls to nfsd_file_put_local() and
 nfsd_serv_put()

Add nfs_to_nfsd_file_put_local() interface to fix race with nfsd
module unload.  Similarly, use RCU around nfs_open_local_fh()'s error
path call to nfs_to->nfsd_serv_put().  Holding RCU ensures that NFS
will safely _call and return_ from its nfs_to calls into the NFSD
functions nfsd_file_put_local() and nfsd_serv_put().

Otherwise, if RCU isn't used then there is a narrow window when NFS's
reference for the nfsd_file and nfsd_serv are dropped and the NFSD
module could be unloaded, which could result in a crash from the
return instruction for either nfs_to->nfsd_file_put_local() or
nfs_to->nfsd_serv_put().

Subject: net: Fix an unsafe loop on the list

The kernel may crash when deleting a genetlink family if there are still
listeners for that family:

Oops: Kernel access of bad area, sig: 11 [#1]
  ...
  NIP [c000000000c080bc] netlink_update_socket_mc+0x3c/0xc0

  Call Trace:

Change the unsafe loop on the list to a safe one, because inside the

Subject: netfs: In readahead, put the folio refs as soon extracted

netfslib currently defers dropping the ref on the folios it obtains during
readahead to after it has started I/O on the basis that we can do it whilst
we wait for the I/O to complete, but this runs the risk of the I/O
collection racing with this in future.

Furthermore, Matthew Wilcox strongly suggests that the refs should be
dropped immediately, as readahead_folio() does (netfslib is using
__readahead_batch() which doesn't drop the refs).

Subject: iomap: share iomap_unshare_iter predicate code with fsdax

The predicate code that iomap_unshare_iter uses to decide if it's really
needs to unshare a file range mapping should be shared with the fsdax
version, because right now they're opencoded and inconsistent.

Note that we simplify the predicate logic a bit -- we no longer allow
unsharing of inline data mappings, but there aren't any filesystems that
allow shared inline data currently.

This is a fix in the sense that it should have been ported to fsdax.

Output GPU page fault restore end event if migration failed.

Subject: drm/amdkfd: SMI report dropped event count

Add new SMI event to report the dropped event count.

When the event kfifo is full, drop count is not zero, or no enough space
left to store the event message, increase drop count.

After reading event out from kfifo, if event was dropped, drop_count is
not zero, generate a dropped event record and reset drop count to zero.

Subject: drm: add DRM_SET_CLIENT_NAME ioctl
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Giving the opportunity to userspace to associate a free-form
name with a drm_file struct is helpful for tracking and debugging.

This is similar to the existing DMA_BUF_SET_NAME ioctl.

Access to client_name is protected by a mutex, and the 'clients' debugfs
file has been updated to print it.

Userspace MR to use this ioctl:
   https://gitlab.freedesktop.org/virgl/virglrenderer/-/merge_requests/1428

If the string passed by userspace contains chars that would mess up output
when it's going to be printed (in dmesg, fdinfo, etc), -EINVAL is returned.

A 0-length string is a valid use, and clears the existing name.

Subject: irqchip/gic-v4: Don't allow a VMOVP on a dying VPE

Kunkun Jiang reported that there is a small window of opportunity for
userspace to force a change of affinity for a VPE while the VPE has already
been unmapped, but the corresponding doorbell interrupt still visible in
/proc/irq/.

Plug the race by checking the value of vmapp_count, which tracks whether
the VPE is mapped ot not, and returning an error in this case.

This involves making vmapp_count common to both GICv4.1 and its v4.0
ancestor.

Subject: wifi: cfg80211: Add wiphy_delayed_work_pending()

Add wiphy_delayed_work_pending() to check if any delayed work timer is
pending, that can be used to be sure that wiphy_delayed_work_queue()
won't postpone an already pending delayed work.

Subject: wifi: radiotap: Avoid -Wflex-array-member-not-at-end warnings

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.

So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `__struct_group()`
helper to create a new tagged `struct ieee80211_radiotap_header_fixed`.
This structure groups together all the members of the flexible
`struct ieee80211_radiotap_header` except the flexible array.

As a result, the array is effectively separated from the rest of the
members without modifying the memory layout of the flexible structure.
We then change the type of the middle struct members currently causing
trouble from `struct ieee80211_radiotap_header` to `struct
ieee80211_radiotap_header_fixed`.

We also want to ensure that in case new members need to be added to the
flexible structure, they are always included within the newly created
tagged struct. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.

This approach avoids having to implement `struct ieee80211_radiotap_header_fixed`
as a completely separate structure, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.

So, with these changes, fix the following warnings:

Subject: net/sched: accept TCA_STAB only for root qdisc

Most qdiscs maintain their backlog using qdisc_pkt_len(skb)
on the assumption it is invariant between the enqueue()
and dequeue() handlers.

Unfortunately syzbot can crash a host rather easily using
a TBF + SFQ combination, with an STAB on SFQ [1]

We can't support TCA_STAB on arbitrary level, this would
require to maintain per-qdisc storage.

Subject: drm/ttm: Move swapped objects off the manager's LRU list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Resources of swapped objects remains on the TTM_PL_SYSTEM manager's
LRU list, which is bad for the LRU walk efficiency.

Rename the device-wide "pinned" list to "unevictable" and move
also resources of swapped-out objects to that list.

An alternative would be to create an "UNEVICTABLE" priority to
be able to keep the pinned- and swapped objects on their
respective manager's LRU without affecting the LRU walk efficiency.

v2:
- Remove a bogus WARN_ON (Christian König)
- Update ttm_resource_[add|del] bulk move (Christian König)
- Fix TTM KUNIT tests (Intel CI)
v3:
- Check for non-NULL bo->resource in ttm_bo_populate().
v4:
- Don't move to LRU tail during swapout until the resource
  is properly swapped or there was a swapout failure.
  (Intel Ci)
- Add a newline after checkpatch check.
v5:
- Introduce ttm_resource_is_swapped() to avoid a corner-case where
  a newly created resource was considered swapped. (Intel CI)
v6:
- Move an assert.

Subject: bcachefs: do not use PF_MEMALLOC_NORECLAIM

Patch series "remove PF_MEMALLOC_NORECLAIM" v3.


This patch (of 2):

bch2_new_inode relies on PF_MEMALLOC_NORECLAIM to try to allocate a new
inode to achieve GFP_NOWAIT semantic while holding locks. If this
allocation fails it will drop locks and use GFP_NOFS allocation context.

We would like to drop PF_MEMALLOC_NORECLAIM because it is really
dangerous to use if the caller doesn't control the full call chain with
this flag set. E.g. if any of the function down the chain needed
GFP_NOFAIL request the PF_MEMALLOC_NORECLAIM would override this and
cause unexpected failure.

While this is not the case in this particular case using the scoped gfp
semantic is not really needed bacause we can easily pus the allocation
context down the chain without too much clutter.

Subject: Revert "mm: introduce PF_MEMALLOC_NORECLAIM, PF_MEMALLOC_NOWARN"

This reverts commit eab0af905bfc3e9c05da2ca163d76a1513159aa4.

There is no existing user of those flags.  PF_MEMALLOC_NOWARN is dangerous
because a nested allocation context can use GFP_NOFAIL which could cause
unexpected failure.  Such a code would be hard to maintain because it
could be deeper in the call chain.

PF_MEMALLOC_NORECLAIM has been added even when it was pointed out [1] that
such a allocation contex is inherently unsafe if the context doesn't fully
control all allocations called from this context.

While PF_MEMALLOC_NOWARN is not dangerous the way PF_MEMALLOC_NORECLAIM is
it doesn't have any user and as Matthew has pointed out we are running out
of those flags so better reclaim it without any real users.

Add a closure version of wait_event_timeout(), with the same semantics.

The closure version is useful because unlike wait_event(), it allows
blocking code to run in the conditional expression.

Subject: rtnetlink: Add bulk registration helpers for rtnetlink message
 handlers.

Before commit addf9b90de22 ("net: rtnetlink: use rcu to free rtnl message
handlers"), once rtnl_msg_handlers[protocol] was allocated, the following
rtnl_register_module() for the same protocol never failed.

However, after the commit, rtnl_msg_handler[protocol][msgtype] needs to
be allocated in each rtnl_register_module(), so each call could fail.

Many callers of rtnl_register_module() do not handle the returned error,
and we need to add many error handlings.

To handle that easily, let's add wrapper functions for bulk registration
of rtnetlink message handlers.

Subject: mctp: Handle error of rtnl_register_module().

Since introduced, mctp has been ignoring the returned value of
rtnl_register_module(), which could fail silently.

Handling the error allows users to view a module as an all-or-nothing
thing in terms of the rtnetlink functionality.  This prevents syzkaller
from reporting spurious errors from its tests, where OOM often occurs
and module is automatically loaded.

Let's handle the errors by rtnl_register_many().

Subject: serial: qcom-geni: fix rx cancel dma status bit

Cancelling an rx command is signalled using bit 14 of the rx DMA status
register and not bit 11.

This bit is currently unused, but this error becomes apparent, for
example, when tracing the status register when closing the port.

Subject: sched/core: Disable page allocation in task_tick_mm_cid()

With KASAN and PREEMPT_RT enabled, calling task_work_add() in
task_tick_mm_cid() may cause the following splat.

[   63.696416] BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48
[   63.696416] in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 610, name: modprobe
[   63.696416] preempt_count: 10001, expected: 0
[   63.696416] RCU nest depth: 1, expected: 1

This problem is caused by the following call trace.

  sched_tick() [ acquire rq->__lock ]
   -> task_tick_mm_cid()
    -> task_work_add()
     -> __kasan_record_aux_stack()
      -> kasan_save_stack()
       -> stack_depot_save_flags()
        -> alloc_pages_mpol_noprof()
         -> __alloc_pages_noprof()
	  -> get_page_from_freelist()
	   -> rmqueue()
	    -> rmqueue_pcplist()
	     -> __rmqueue_pcplist()
	      -> rmqueue_bulk()
	       -> rt_spin_lock()

The rq lock is a raw_spinlock_t. We can't sleep while holding
it. IOW, we can't call alloc_pages() in stack_depot_save_flags().

The task_tick_mm_cid() function with its task_work_add() call was
introduced by commit 223baf9d17f2 ("sched: Fix performance regression
introduced by mm_cid") in v6.4 kernel.

Fortunately, there is a kasan_record_aux_stack_noalloc() variant that
calls stack_depot_save_flags() while not allowing it to allocate
new pages.  To allow task_tick_mm_cid() to use task_work without
page allocation, a new TWAF_NO_ALLOC flag is added to enable calling
kasan_record_aux_stack_noalloc() instead of kasan_record_aux_stack()
if set. The task_tick_mm_cid() function is modified to add this new flag.

The possible downside is the missing stack trace in a KASAN report due
to new page allocation required when task_work_add_noallloc() is called
which should be rare.

Hardcoded driver date is useless, so use kernel version as a driver date
to make identifying .ko file easier. Also allow to pass DRIVER_DATE
on build time to allow versioning the driver in case it is built out
of the tree.

Subject: sched/fair: Fix external p->on_rq users

Sean noted that ever since commit 152e11f6df29 ("sched/fair: Implement
delayed dequeue") KVM's preemption notifiers have started
mis-classifying preemption vs blocking.

Notably p->on_rq is no longer sufficient to determine if a task is
runnable or blocked -- the aforementioned commit introduces tasks that
remain on the runqueue even through they will not run again, and
should be considered blocked for many cases.

Add the task_is_runnable() helper to classify things and audit all
external users of the p->on_rq state. Also add a few comments.

-/**
- * DOC: overview
- *
- * A graphics device might be supported by different drivers, but only one
- * driver can be active at any given time. Many systems load a generic
- * graphics drivers, such as EFI-GOP or VESA, early during the boot process.
- * During later boot stages, they replace the generic driver with a dedicated,
- * hardware-specific driver. To take over the device the dedicated driver
- * first has to remove the generic driver. DRM aperture functions manage
- * ownership of DRM framebuffer memory and hand-over between drivers.
- *
- * DRM drivers should call drm_aperture_remove_conflicting_framebuffers()
- * at the top of their probe function. The function removes any generic
- * driver that is currently associated with the given framebuffer memory.
- * If the framebuffer is located at PCI BAR 0, the rsp code looks as in the
- * example given below.
- *
- * .. code-block:: c
- *
- *	static const struct drm_driver example_driver = {
- *		...
- *	};
- *
- *	static int remove_conflicting_framebuffers(struct pci_dev *pdev)
- *	{
- *		resource_size_t base, size;
- *		int ret;
- *
- *		base = pci_resource_start(pdev, 0);
- *		size = pci_resource_len(pdev, 0);
- *
- *		return drm_aperture_remove_conflicting_framebuffers(base, size,
- *		                                                    &example_driver);
- *	}
- *
- *	static int probe(struct pci_dev *pdev)
- *	{
- *		int ret;
- *
- *		// Remove any generic drivers...
- *		ret = remove_conflicting_framebuffers(pdev);
- *		if (ret)
- *			return ret;
- *
- *		// ... and initialize the hardware.
- *		...
- *
- *		drm_dev_register();
- *
- *		return 0;
- *	}
- *
- * PCI device drivers should call
- * drm_aperture_remove_conflicting_pci_framebuffers() and let it detect the
- * framebuffer apertures automatically. Device drivers without knowledge of
- * the framebuffer's location shall call drm_aperture_remove_framebuffers(),
- * which removes all drivers for known framebuffer.
- *
- * Drivers that are susceptible to being removed by other drivers, such as
- * generic EFI or VESA drivers, have to register themselves as owners of their
- * given framebuffer memory. Ownership of the framebuffer memory is achieved
- * by calling devm_aperture_acquire_from_firmware(). On success, the driver
- * is the owner of the framebuffer range. The function fails if the
- * framebuffer is already owned by another driver. See below for an example.
- *
- * .. code-block:: c
- *
- *	static int acquire_framebuffers(struct drm_device *dev, struct platform_device *pdev)
- *	{
- *		resource_size_t base, size;
- *
- *		mem = platform_get_resource(pdev, IORESOURCE_MEM, 0);
- *		if (!mem)
- *			return -EINVAL;
- *		base = mem->start;
- *		size = resource_size(mem);
- *
- *		return devm_acquire_aperture_from_firmware(dev, base, size);
- *	}
- *
- *	static int probe(struct platform_device *pdev)
- *	{
- *		struct drm_device *dev;
- *		int ret;
- *
- *		// ... Initialize the device...
- *		dev = devm_drm_dev_alloc();
- *		...
- *
- *		// ... and acquire ownership of the framebuffer.
- *		ret = acquire_framebuffers(dev, pdev);
- *		if (ret)
- *			return ret;
- *
- *		drm_dev_register(dev, 0);
- *
- *		return 0;
- *	}
- *
- * The generic driver is now subject to forced removal by other drivers. This
- * only works for platform drivers that support hot unplug.
- * When a driver calls drm_aperture_remove_conflicting_framebuffers() et al.
- * for the registered framebuffer range, the aperture helpers call
- * platform_device_unregister() and the generic driver unloads itself. It
- * may not access the device's registers, framebuffer memory, ROM, etc
- * afterwards.

The DisCo for SoundWire 2.0 spec adds support for a new
sdw-manager-list property.  Add it in backwards-compatible mode with
'sdw-master-count', which assumed that all links between 0..count-1
exist.

Subject: iomap: remove iomap_file_buffered_write_punch_delalloc

Currently iomap_file_buffered_write_punch_delalloc can be called from
XFS either with the invalidate lock held or not.  To fix this while
keeping the locking in the file system and not the iomap library
code we'll need to life the locking up into the file system.

To prepare for that, open code iomap_file_buffered_write_punch_delalloc
in the only caller, and instead export iomap_write_delalloc_release.

Subject: gpu: host1x: Set up device DMA parameters

In order to store device DMA parameters, the DMA framework depends on
the device's dma_parms field to point at a valid memory location. Add
backing storage for this in struct host1x_memory_context and point to
it.

Subject: genetlink: hold RCU in genlmsg_mcast()

While running net selftests with CONFIG_PROVE_RCU_LIST=y I saw
one lockdep splat [1].

genlmsg_mcast() uses for_each_net_rcu(), and must therefore hold RCU.

Instead of letting all callers guard genlmsg_multicast_allns()
with a rcu_read_lock()/rcu_read_unlock() pair, do it in genlmsg_mcast().

This also means the @flags parameter is useless, we need to always use
GFP_ATOMIC.

Subject: ublk: don't allow user copy for unprivileged device

UBLK_F_USER_COPY requires userspace to call write() on ublk char
device for filling request buffer, and unprivileged device can't
be trusted.

So don't allow user copy for unprivileged device.

Subject: mm: percpu: increase PERCPU_DYNAMIC_SIZE_SHIFT on certain builds.

Arnd reported a build failure due to the BUILD_BUG_ON() statement in
alloc_kmem_cache_cpus().  The test

  PERCPU_DYNAMIC_EARLY_SIZE < NR_KMALLOC_TYPES * KMALLOC_SHIFT_HIGH * sizeof(struct kmem_cache_cpu)

The factors that increase the right side of the equation:
- PAGE_SIZE > 4KiB increases KMALLOC_SHIFT_HIGH
- For the local_lock_t in kmem_cache_cpu:
  - PREEMPT_RT adds an actual lock.
  - LOCKDEP increases the size of the lock.
  - LOCK_STAT adds additional bytes plus padding to the lockdep
    structure.

The net difference with and without PREEMPT_RT is 88 bytes for the
lock_lock_t, 96 bytes for kmem_cache_cpu due to additional padding.  This
is enough to exceed the 80KiB limit with 16KiB page size - the 8KiB page
size is fine.

Increase PERCPU_DYNAMIC_SIZE_SHIFT to 13 on configs with PAGE_SIZE larger
than 4KiB and LOCKDEP enabled.

Subject: mm: khugepaged: fix the arguments order in khugepaged_collapse_file
 trace point

The "addr" and "is_shmem" arguments have different order in TP_PROTO and
TP_ARGS.  This resulted in the incorrect trace result:

text-hugepage-644429 [276] 392092.878683: mm_khugepaged_collapse_file:
mm=0xffff20025d52c440, hpage_pfn=0x200678c00, index=512, addr=1, is_shmem=0,
filename=text-hugepage, nr=512, result=failed

The value of "addr" is wrong because it was treated as bool value, the
type of is_shmem.

Fix the order in TP_PROTO to keep "addr" is before "is_shmem" since the
original patch review suggested this order to achieve best packing.

And use "lx" for "addr" instead of "ld" in TP_printk because address is
typically shown in hex.

After the fix, the trace result looks correct:

text-hugepage-7291  [004]   128.627251: mm_khugepaged_collapse_file:
mm=0xffff0001328f9500, hpage_pfn=0x20016ea00, index=512, addr=0x400000,

Subject: mm: huge_memory: add vma_thp_disabled() and thp_disabled_by_hw()

Patch series "mm: don't install PMD mappings when THPs are disabled by the
hw/process/vma".

During testing, it was found that we can get PMD mappings in processes
where THP (and more precisely, PMD mappings) are supposed to be disabled.
While it works as expected for anon+shmem, the pagecache is the
problematic bit.

For s390 KVM this currently means that a VM backed by a file located on
filesystem with large folio support can crash when KVM tries accessing the
problematic page, because the readahead logic might decide to use a
PMD-sized THP and faulting it into the page tables will install a PMD
mapping, something that s390 KVM cannot tolerate.

This might also be a problem with HW that does not support PMD mappings,
but I did not try reproducing it.

Fix it by respecting the ways to disable THPs when deciding whether we can
install a PMD mapping.  khugepaged should already be taking care of not
collapsing if THPs are effectively disabled for the hw/process/vma.


This patch (of 2):

Add vma_thp_disabled() and thp_disabled_by_hw() helpers to be shared by
shmem_allowable_huge_orders() and __thp_vma_allowable_orders().

[david@redhat.com: rename to vma_thp_disabled(), split out thp_disabled_by_hw() ]

Subject: drm/sched: Optimise drm_sched_entity_push_job
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In FIFO mode (which is the default), both drm_sched_entity_push_job() and
drm_sched_rq_update_fifo(), where the latter calls the former, are
currently taking and releasing the same entity->rq_lock.

We can avoid that design inelegance, and also have a miniscule
efficiency improvement on the submit from idle path, by introducing a new
drm_sched_rq_update_fifo_locked() helper and pulling up the lock taking to
its callers.

v2:
 * Remove drm_sched_rq_update_fifo() altogether. (Christian)

v3:
 * Improved commit message. (Philipp)

Subject: drm/sched: Re-order struct drm_sched_rq members for clarity
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Current kerneldoc for struct drm_sched_rq incompletely documents what
fields are protected by the lock.

This is not good because it is misleading.

Lets fix it by listing all the elements which are protected by the lock.

While at it, lets also re-order the members so all protected by the lock
are in a single group.

v2:
 * Refer variables by kerneldoc syntax, more verbose commit text. (Philipp)

Subject: drm/sched: Re-group and rename the entity run-queue lock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When writing to a drm_sched_entity's run-queue, writers are protected
through the lock drm_sched_entity.rq_lock. This naming, however,
frequently collides with the separate internal lock of struct
drm_sched_rq, resulting in uses like this:

	spin_lock(&entity->rq_lock);
	spin_lock(&entity->rq->lock);

Rename drm_sched_entity.rq_lock to improve readability. While at it,
re-order that struct's members to make it more obvious what the lock
protects.

v2:
 * Rename some rq_lock straddlers in kerneldoc, improve commit text. (Philipp)

Subject: drm/sched: Further optimise drm_sched_entity_push_job
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Having removed one re-lock cycle on the entity->lock in a patch titled
"drm/sched: Optimise drm_sched_entity_push_job", with only a tiny bit
larger refactoring we can do the same optimisation on the rq->lock.
(Currently both drm_sched_rq_add_entity() and
drm_sched_rq_update_fifo_locked() take and release the same lock.)

To achieve this we make drm_sched_rq_update_fifo_locked() and
drm_sched_rq_add_entity() expect the rq->lock to be held.

We also align drm_sched_rq_update_fifo_locked(),
drm_sched_rq_add_entity() and
drm_sched_rq_remove_fifo_locked() function signatures, by adding rq as a
parameter to the latter.

v2:
 * Fix after rebase of the series.
 * Avoid naming inconsistency between drm_sched_rq_add/remove. (Christian)

Subject: drm/bridge: synopsys: Add DW HDMI QP TX Controller support library

The Synopsys DesignWare HDMI 2.1 Quad-Pixel (QP) TX Controller IP
supports the following features, among others:

* Fixed Rate Link (FRL)
* Display Stream Compression (DSC)
* 4K@120Hz and 8K@60Hz video modes
* Variable Refresh Rate (VRR) including Quick Media Switching (QMS), aka
  Cinema VRR
* Fast Vactive (FVA), aka Quick Frame Transport (QFT)
* SCDC I2C DDC access
* TMDS Scrambler enabling 2160p@60Hz with RGB/YCbCr4:4:4
* YCbCr4:2:0 enabling 2160p@60Hz at lower HDMI link speeds
* Multi-stream audio
* Enhanced Audio Return Channel (EARC)

Add library containing common helpers to enable basic support, i.e. RGB
output up to 4K@30Hz, without audio, CEC or any HDMI 2.1 specific
features.

Subject: dma-mapping: fix tracing dma_alloc/free with vmalloc'd memory

Not all virtual addresses have physical addresses, such as if they were
vmalloc'd. Just trace the virtual address instead of trying to trace a
physical address. This aligns with the API, and is good enough to
associate dma_alloc with dma_free.

Fixes: 038eb433dc14 ("dma-mapping: add tracing for dma-mapping API calls")
Reported-by: syzbot+b4bfacdec173efaa8567@syzkaller.appspotmail.com

Subject: drm/client: Move client event handlers to drm_client_event.c

A number of DRM-client functions serve as entry points from device
operations to client code. Moving them info a separate file will later
allow for a more fine-grained kernel configuration. For most of the
users it is sufficient to include <drm/drm_client_event.h> instead of
the full driver-side interface in <drm/drm_client.h>

v2:
- rename new files to drm_client_event.{c,h}

From bf17766f108309027aac2bfe184df6088dfd7384 Mon Sep 17 00:00:00 2001
From: Thomas Zimmermann <tzimmermann@suse.de>
Date: Mon, 14 Oct 2024 10:55:21 +0200
Subject: drm/client: Move suspend/resume into DRM client callbacks

Suspend and resume is still tied to fbdev emulation. Modeset helpers
and several drivers call drm_fb_helper_set_suspend_unlocked() to inform
the fbdev client about suspend/resume events.

To make it work with arbitrary clients, add per-client callback
functions for suspend and resume. Implement them for fbdev emulation
with the existing drm_fb_helper_set_suspend_unlocked(). Then update
DRM's modeset helpers to call the new interface.

Clients that are not fbdev can now implement suspend/resume to their
requirements.

The callback parameter holds_console_lock is a workaround for i915,
radeon and xe, which possibly call the interface while having the
console lock acquired. Even though the commit doesn't modify these
drivers, it already adds the flag to avoid churn later on. New code
should not hold the console lock.

v4:
- clarify holds_console_lock in commit description (Jonathan)

Subject: drm/client: Make client support optional
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Only build client code if DRM_CLIENT has been selected. Automatially
do so if one of the default clients has been enabled. If client support
has been disabled, the helpers for client-related events are empty and
the regular client functions are not present.

Amdgpu has an internal DRM client, so it has to select DRM_CLIENT by
itself unconditionally.

v3:
- provide empty drm_client_debugfs_init() if DRM_CLIENT=n (kernel
  test robot)

Subject: xen: Remove dependency between pciback and privcmd
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 2fae6bb7be32 ("xen/privcmd: Add new syscall to get gsi from dev")
adds a weak reverse dependency to the config XEN_PRIVCMD definition, that
dependency causes xen-privcmd can't be loaded on domU, because dependent
xen-pciback isn't always be loaded successfully on domU.

To solve above problem, remove that dependency, and do not call
pcistub_get_gsi_from_sbdf() directly, instead add a hook in
drivers/xen/apci.c, xen-pciback register the real call function, then in
privcmd_ioctl_pcidev_get_gsi call that hook.

Fixes: 2fae6bb7be32 ("xen/privcmd: Add new syscall to get gsi from dev")

Subject: net: fix races in netdev_tx_sent_queue()/dev_watchdog()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some workloads hit the infamous dev_watchdog() message:

"NETDEV WATCHDOG: eth0 (xxxx): transmit queue XX timed out"

It seems possible to hit this even for perfectly normal
BQL enabled drivers:

1) Assume a TX queue was idle for more than dev->watchdog_timeo
   (5 seconds unless changed by the driver)

2) Assume a big packet is sent, exceeding current BQL limit.

3) Driver ndo_start_xmit() puts the packet in TX ring,
   and netdev_tx_sent_queue() is called.

4) QUEUE_STATE_STACK_XOFF could be set from netdev_tx_sent_queue()
   before txq->trans_start has been written.

5) txq->trans_start is written later, from netdev_start_xmit()

    if (rc == NETDEV_TX_OK)
          txq_trans_update(txq)

dev_watchdog() running on another cpu could read the old
txq->trans_start, and then see QUEUE_STATE_STACK_XOFF, because 5)
did not happen yet.

To solve the issue, write txq->trans_start right before one XOFF bit
is set :

- _QUEUE_STATE_DRV_XOFF from netif_tx_stop_queue()
- __QUEUE_STATE_STACK_XOFF from netdev_tx_sent_queue()

From dev_watchdog(), we have to read txq->state before txq->trans_start.

Add memory barriers to enforce correct ordering.

In the future, we could avoid writing over txq->trans_start for normal
operations, and rename this field to txq->xoff_start_time.

Subject: fs/super.c: introduce get_tree_bdev_flags()

As Allison reported [1], currently get_tree_bdev() will store
"Can't lookup blockdev" error message.  Although it makes sense for
pure bdev-based fses, this message may mislead users who try to use
EROFS file-backed mounts since get_tree_nodev() is used as a fallback
then.

Add get_tree_bdev_flags() to specify extensible flags [2] and
GET_TREE_BDEV_QUIET_LOOKUP to silence "Can't lookup blockdev" message
since it's misleading to EROFS file-backed mounts now.

From d2f8671045b41871053dedaf3035a06ad53d2736 Mon Sep 17 00:00:00 2001
From: Bibo Mao <maobibo@loongson.cn>
Date: Mon, 21 Oct 2024 22:11:19 +0800
Subject: LoongArch: Set initial pte entry with PAGE_GLOBAL for kernel space

There are two pages in one TLB entry on LoongArch system. For kernel
space, it requires both two pte entries (buddies) with PAGE_GLOBAL bit
set, otherwise HW treats it as non-global tlb, there will be potential
problems if tlb entry for kernel space is not global. Such as fail to
flush kernel tlb with the function local_flush_tlb_kernel_range() which
supposed only flush tlb with global bit.

Kernel address space areas include percpu, vmalloc, vmemmap, fixmap and
kasan areas. For these areas both two consecutive page table entries
should be enabled with PAGE_GLOBAL bit. So with function set_pte() and
pte_clear(), pte buddy entry is checked and set besides its own pte
entry. However it is not atomic operation to set both two pte entries,
there is problem with test_vmalloc test case.

So function kernel_pte_init() is added to init a pte table when it is
created for kernel address space, and the default initial pte value is
PAGE_GLOBAL rather than zero at beginning. Then only its own pte entry
need update with function set_pte() and pte_clear(), nothing to do with
the pte buddy entry.

iomap_want_unshare_iter currently sits in fs/iomap/buffered-io.c, which
depends on CONFIG_BLOCK.  It is also in used in fs/dax.c whіch has no
such dependency.  Given that it is a trivial check turn it into an inline
in include/linux/iomap.h to fix the DAX && !BLOCK build.

Subject: drm/fbdev: fix drm_fb_helper_deferred_io() build failure

The drm_fb_helper_deferred_io() uses struct fb_deferred_io_pageref,
which isn't available without CONFIG_FB_DEFERRED_IO. Put the function
under corresponding #ifdef to fix build failure if deferred I/O isn't
enabled.

Subject: bpf: Add MEM_WRITE attribute

Add a MEM_WRITE attribute for BPF helper functions which can be used in
bpf_func_proto to annotate an argument type in order to let the verifier
know that the helper writes into the memory passed as an argument. In
the past MEM_UNINIT has been (ab)used for this function, but the latter
merely tells the verifier that the passed memory can be uninitialized.

There have been bugs with overloading the latter but aside from that
there are also cases where the passed memory is read + written which
currently cannot be expressed, see also 4b3786a6c539 ("bpf: Zero former
ARG_PTR_TO_{LONG,INT} args in case of error").

Subject: kasan: Fix Software Tag-Based KASAN with GCC

Per [1], -fsanitize=kernel-hwaddress with GCC currently does not disable
instrumentation in functions with __attribute__((no_sanitize_address)).

However, __attribute__((no_sanitize("hwaddress"))) does correctly
disable instrumentation. Use it instead.

Subject: afs: Fix missing subdir edit when renamed between parent dirs

When rename moves an AFS subdirectory between parent directories, the
subdir also needs a bit of editing: the ".." entry needs updating to point
to the new parent (though I don't make use of the info) and the DV needs
incrementing by 1 to reflect the change of content.  The server also sends
a callback break notification on the subdirectory if we have one, but we
can take care of recovering the promise next time we access the subdir.

This can be triggered by something like:

    mount -t afs %example.com:xfstest.test20 /xfstest.test/
    mkdir /xfstest.test/{aaa,bbb,aaa/ccc}
    touch /xfstest.test/bbb/ccc/d
    mv /xfstest.test/{aaa/ccc,bbb/ccc}
    touch /xfstest.test/bbb/ccc/e

When the pathwalk for the second touch hits "ccc", kafs spots that the DV
is incorrect and downloads it again (so the fix is not critical).

Fix this, if the rename target is a directory and the old and new
parents are different, by:

 (1) Incrementing the DV number of the target locally.

 (2) Editing the ".." entry in the target to refer to its new parent's
     vnode ID and uniquifier.

Follow the interlace_allowed example and calculate drm_connector's
ycbcr_420_allowed flag as AND of all drm_bridge's ycbcr_420_allowed
flags in a chain. This is one of the gaps between several
bridge-specific connector implementations and drm_bridge_connector.

Subject: drm/sched: warn about drm_sched_job_init()'s partial init

drm_sched_job_init()'s name suggests that after the function succeeded,
parameter "job" will be fully initialized. This is not the case; some
members are only later set, notably drm_sched_job.sched by
drm_sched_job_arm().

Document that drm_sched_job_init() does not set all struct members.

Document the lifetime of drm_sched_job.sched.

Subject: cxl/port: Fix use-after-free, permit out-of-order decoder shutdown

In support of investigating an initialization failure report [1],
cxl_test was updated to register mock memory-devices after the mock
root-port/bus device had been registered. That led to cxl_test crashing
with a use-after-free bug with the following signature:

    cxl_port_attach_region: cxl region3: cxl_host_bridge.0:port3 decoder3.0 add: mem0:decoder7.0 @ 0 next: cxl_switch_uport.0 nr_eps: 1 nr_targets: 1
    cxl_port_attach_region: cxl region3: cxl_host_bridge.0:port3 decoder3.0 add: mem4:decoder14.0 @ 1 next: cxl_switch_uport.0 nr_eps: 2 nr_targets: 1
    cxl_port_setup_targets: cxl region3: cxl_switch_uport.0:port6 target[0] = cxl_switch_dport.0 for mem0:decoder7.0 @ 0
1)  cxl_port_setup_targets: cxl region3: cxl_switch_uport.0:port6 target[1] = cxl_switch_dport.4 for mem4:decoder14.0 @ 1
    [..]
    cxld_unregister: cxl decoder14.0:
    cxl_region_decode_reset: cxl_region region3:
    mock_decoder_reset: cxl_port port3: decoder3.0 reset
2)  mock_decoder_reset: cxl_port port3: decoder3.0: out of order reset, expected decoder3.1
    cxl_endpoint_decoder_release: cxl decoder14.0:
    [..]
    cxld_unregister: cxl decoder7.0:
3)  cxl_region_decode_reset: cxl_region region3:
    Oops: general protection fault, probably for non-canonical address 0x6b6b6b6b6b6b6bc3: 0000 [#1] PREEMPT SMP PTI
    [..]
    RIP: 0010:to_cxl_port+0x8/0x60 [cxl_core]
    [..]
    Call Trace:
     <TASK>
     cxl_region_decode_reset+0x69/0x190 [cxl_core]
     cxl_region_detach+0xe8/0x210 [cxl_core]
     cxl_decoder_kill_region+0x27/0x40 [cxl_core]
     cxld_unregister+0x5d/0x60 [cxl_core]

At 1) a region has been established with 2 endpoint decoders (7.0 and
14.0). Those endpoints share a common switch-decoder in the topology
(3.0). At teardown, 2), decoder14.0 is the first to be removed and hits
the "out of order reset case" in the switch decoder. The effect though
is that region3 cleanup is aborted leaving it in-tact and
referencing decoder14.0. At 3) the second attempt to teardown region3
trips over the stale decoder14.0 object which has long since been
deleted.

The fix here is to recognize that the CXL specification places no
mandate on in-order shutdown of switch-decoders, the driver enforces
in-order allocation, and hardware enforces in-order commit. So, rather
than fail and leave objects dangling, always remove them.

In support of making cxl_region_decode_reset() always succeed,
cxl_region_invalidate_memregion() failures are turned into warnings.
Crashing the kernel is ok there since system integrity is at risk if
caches cannot be managed around physical address mutation events like
CXL region destruction.

A new device_for_each_child_reverse_from() is added to cleanup
port->commit_end after all dependent decoders have been disabled. In
other words if decoders are allocated 0->1->2 and disabled 1->2->0 then
port->commit_end only decrements from 2 after 2 has been disabled, and
it decrements all the way to zero since 1 was disabled previously.

Subject: posix-cpu-timers: Clear TICK_DEP_BIT_POSIX_TIMER on clone

When cloning a new thread, its posix_cputimers are not inherited, and
are cleared by posix_cputimers_init(). However, this does not clear the
tick dependency it creates in tsk->tick_dep_mask, and the handler does
not reach the code to clear the dependency if there were no timers to
begin with.

Thus if a thread has a cputimer running before clone/fork, all
descendants will prevent nohz_full unless they create a cputimer of
their own.

Fix this by entirely clearing the tick_dep_mask in copy_process().
(There is currently no inherited state that needs a tick dependency)

Process-wide timers do not have this problem because fork does not copy
signal_struct as a baseline, it creates one from scratch.

Subject: fork: do not invoke uffd on fork if error occurs

Patch series "fork: do not expose incomplete mm on fork".

During fork we may place the virtual memory address space into an
inconsistent state before the fork operation is complete.

In addition, we may encounter an error during the fork operation that
indicates that the virtual memory address space is invalidated.

As a result, we should not be exposing it in any way to external machinery
that might interact with the mm or VMAs, machinery that is not designed to
deal with incomplete state.

We specifically update the fork logic to defer khugepaged and ksm to the
end of the operation and only to be invoked if no error arose, and
disallow uffd from observing fork events should an error have occurred.


This patch (of 2):

Currently on fork we expose the virtual address space of a process to
userland unconditionally if uffd is registered in VMAs, regardless of
whether an error arose in the fork.

This is performed in dup_userfaultfd_complete() which is invoked
unconditionally, and performs two duties - invoking registered handlers
for the UFFD_EVENT_FORK event via dup_fctx(), and clearing down
userfaultfd_fork_ctx objects established in dup_userfaultfd().

This is problematic, because the virtual address space may not yet be
correctly initialised if an error arose.

The change in commit d24062914837 ("fork: use __mt_dup() to duplicate
maple tree in dup_mmap()") makes this more pertinent as we may be in a
state where entries in the maple tree are not yet consistent.

We address this by, on fork error, ensuring that we roll back state that
we would otherwise expect to clean up through the event being handled by
userland and perform the memory freeing duty otherwise performed by
dup_userfaultfd_complete().

We do this by implementing a new function, dup_userfaultfd_fail(), which
performs the same loop, only decrementing reference counts.

Note that we perform mmgrab() on the parent and child mm's, however
userfaultfd_ctx_put() will mmdrop() this once the reference count drops to
zero, so we will avoid memory leaks correctly here.

Subject: fork: only invoke khugepaged, ksm hooks if no error

There is no reason to invoke these hooks early against an mm that is in an
incomplete state.

The change in commit d24062914837 ("fork: use __mt_dup() to duplicate
maple tree in dup_mmap()") makes this more pertinent as we may be in a
state where entries in the maple tree are not yet consistent.

Their placement early in dup_mmap() only appears to have been meaningful
for early error checking, and since functionally it'd require a very small
allocation to fail (in practice 'too small to fail') that'd only occur in
the most dire circumstances, meaning the fork would fail or be OOM'd in
any case.

Since both khugepaged and KSM tracking are there to provide optimisations
to memory performance rather than critical functionality, it doesn't
really matter all that much if, under such dire memory pressure, we fail
to register an mm with these.

As a result, we follow the example of commit d2081b2bf819 ("mm:
khugepaged: make khugepaged_enter() void function") and make ksm_fork() a
void function also.

We only expose the mm to these functions once we are done with them and
only if no error occurred in the fork operation.

ensure that interrupts will be disabled on the CPU holding it.

Subject: ipv4: ip_tunnel: Fix suspicious RCU usage warning in
 ip_tunnel_init_flow()

There are code paths from which the function is called without holding
the RCU read lock, resulting in a suspicious RCU usage warning [1].

Fix by using l3mdev_master_upper_ifindex_by_index() which will acquire
the RCU read lock before calling
l3mdev_master_upper_ifindex_by_index_rcu().

Subject: accel/ivpu: Remove copy engine support

Copy engine was deprecated by the FW and is no longer supported.
Compute engine includes all copy engine functionality and should be used
instead.

This change does not affect user space as the copy engine was never
used outside of a couple of tests.

Subject: bpf: Add bpf_mem_alloc_check_size() helper

Introduce bpf_mem_alloc_check_size() to check whether the allocation
size exceeds the limitation for the kmalloc-equivalent allocator. The
upper limit for percpu allocation is LLIST_NODE_SZ bytes larger than
non-percpu allocation, so a percpu argument is added to the helper.

The helper will be used in the following patch to check whether the size
parameter passed to bpf_mem_alloc() is too big.

Subject: x86/uaccess: Avoid barrier_nospec() in 64-bit copy_from_user()

The barrier_nospec() in 64-bit copy_from_user() is slow. Instead use
pointer masking to force the user pointer to all 1's for an invalid
address.

The kernel test robot reports a 2.6% improvement in the per_thread_ops
benchmark [1].

This is a variation on a patch originally by Josh Poimboeuf [2].

Subject: mm/codetag: fix null pointer check logic for ref and tag

When we compile and load lib/slub_kunit.c,it will cause a panic.

The root cause is that __kmalloc_cache_noprof was directly called instead
of kmem_cache_alloc,which resulted in no alloc_tag being allocated.This
caused current->alloc_tag to be null,leading to a null pointer dereference
in alloc_tag_ref_set.

Despite the fact that my colleague Pei Xiao will later fix the code in
slub_kunit.c,we still need fix null pointer check logic for ref and tag to
avoid panic caused by a null pointer dereference.

Here is the log for the panic:

Subject: mm, swap: avoid over reclaim of full clusters

When running low on usable slots, cluster allocator will try to reclaim
the full clusters aggressively to reclaim HAS_CACHE slots.  This
guarantees that as long as there are any usable slots, HAS_CACHE or not,
the swap device will be usable and workload won't go OOM early.

Before the cluster allocator, swap allocator fails easily if device is
filled up with reclaimable HAS_CACHE slots.  Which can be easily
reproduced with following simple program:

    #include <stdio.h>
    #include <string.h>
    #include <linux/mman.h>
    #include <sys/mman.h>
    #define SIZE 8192UL * 1024UL * 1024UL
    int main(int argc, char **argv) {
        long tmp;
        char *p = mmap(NULL, SIZE, PROT_READ | PROT_WRITE,
               MAP_PRIVATE | MAP_ANONYMOUS, -1, 0);
        memset(p, 0, SIZE);

        getchar(); /* Pause */
        return 0;
    }

Setup an 8G non ramdisk swap, the first run of the program will swapout 8G
ram successfully.  But run same program again after the first run paused,
the second run can't swapout all 8G memory as now half of the swap device
is pinned by HAS_CACHE.  There was a random scan in the old allocator that
may reclaim part of the HAS_CACHE by luck, but it's unreliable.

The new allocator's added reclaim of full clusters when device is low on
usable slots.  But when multiple CPUs are seeing the device is low on
usable slots at the same time, they ran into a thundering herd problem.

This is an observable problem on large machine with mass parallel
workload, as full cluster reclaim is slower on large swap device and
higher number of CPUs will also make things worse.

Testing using a 128G ZRAM on a 48c96t system.  When the swap device is
very close to full (eg.  124G / 128G), running build linux kernel with
make -j96 in a 1G memory cgroup will hung (not a softlockup though)
spinning in full cluster reclaim for about ~5min before go OOM.

To solve this, split the full reclaim into two parts:

- Instead of do a synchronous aggressively reclaim when device is low,
  do only one aggressively reclaim when device is strictly full with a
  kworker. This still ensures in worst case the device won't be unusable
  because of HAS_CACHE slots.

- To avoid allocation (especially higher order) suffer from HAS_CACHE
  filling up clusters and kworker not responsive enough, do one synchronous
  scan every time the free list is drained, and only scan one cluster. This
  is kind of similar to the random reclaim before, keeps the full clusters
  rotated and has a minimal latency. This should provide a fair reclaim
  strategy suitable for most workloads.

Subject: mm: allow set/clear page_type again

Some page flags (page->flags) were converted to page types
(page->page_types).  A recent example is PG_hugetlb.

From the exclusive writer's perspective, e.g., a thread doing
__folio_set_hugetlb(), there is a difference between the page flag and
type APIs: the former allows the same non-atomic operation to be repeated
whereas the latter does not.  For example, calling __folio_set_hugetlb()
twice triggers VM_BUG_ON_FOLIO(), since the second call expects the type
(PG_hugetlb) not to be set previously.

Using add_hugetlb_folio() as an example, it calls __folio_set_hugetlb() in
the following error-handling path.  And when that happens, it triggers the
aforementioned VM_BUG_ON_FOLIO().

  if (folio_test_hugetlb(folio)) {
    rc = hugetlb_vmemmap_restore_folio(h, folio);
    if (rc) {
      spin_lock_irq(&hugetlb_lock);
      add_hugetlb_folio(h, folio, false);
      ...

It is possible to make hugeTLB comply with the new requirements from the
page type API.  However, a straightforward fix would be to just allow the
same page type to be set or cleared again inside the API, to avoid any
changes to its callers.

As Maxime suggested, add a new helper
drm_kunit_display_mode_from_cea_vic(), it can replace the direct call
of drm_display_mode_from_cea_vic(), and it will help solving
the `mode` memory leaks.

Subject: Input: fix regression when re-registering input handlers

Commit d469647bafd9 ("Input: simplify event handling logic") introduced
code that would set handler->events() method to either
input_handler_events_filter() or input_handler_events_default() or
input_handler_events_null(), depending on the kind of input handler
(a filter or a regular one) we are dealing with. Unfortunately this
breaks cases when we try to re-register the same filter (as is the case
with sysrq handler): after initial registration the handler will have 2
event handling methods defined, and will run afoul of the check in
input_handler_check_methods():

	input: input_handler_check_methods: only one event processing method can be defined (sysrq)
	sysrq: Failed to register input handler, error -22

Fix this by adding handle_events() method to input_handle structure and
setting it up when registering a new input handle according to event
handling methods defined in associated input_handler structure, thus
avoiding modifying the input_handler structure.

Subject: mm: multi-gen LRU: remove MM_LEAF_OLD and MM_NONLEAF_TOTAL stats

Patch series "mm: multi-gen LRU: Have secondary MMUs participate in
MM_WALK".

Today, the MM_WALK capability causes MGLRU to clear the young bit from
PMDs and PTEs during the page table walk before eviction, but MGLRU does
not call the clear_young() MMU notifier in this case.  By not calling this
notifier, the MM walk takes less time/CPU, but it causes pages that are
accessed mostly through KVM / secondary MMUs to appear younger than they
should be.

We do call the clear_young() notifier today, but only when attempting to
evict the page, so we end up clearing young/accessed information less
frequently for secondary MMUs than for mm PTEs, and therefore they appear
younger and are less likely to be evicted.  Therefore, memory that is
*not* being accessed mostly by KVM will be evicted *more* frequently,
worsening performance.

ChromeOS observed a tab-open latency regression when enabling MGLRU with a
setup that involved running a VM:

		Tab-open latency histogram (ms)
Version		p50	mean	p95	p99	max
base		1315	1198	2347	3454	10319
mglru		2559	1311	7399	12060	43758
fix		1119	926	2470	4211	6947

This series replaces the final non-selftest patchs from this series[1],
which introduced a similar change (and a new MMU notifier) with KVM
optimizations.  I'll send a separate series (to Sean and Paolo) for the
KVM optimizations.

This series also makes proactive reclaim with MGLRU possible for KVM
memory.  I have verified that this functions correctly with the selftest
from [1], but given that that test is a KVM selftest, I'll send it with
the rest of the KVM optimizations later.  Andrew, let me know if you'd
like to take the test now anyway.

This patch (of 2):

The removed stats, MM_LEAF_OLD and MM_NONLEAF_TOTAL, are not very helpful
and become more complicated to properly compute when adding
test/clear_young() notifiers in MGLRU's mm walk.

Subject: mm: multi-gen LRU: use {ptep,pmdp}_clear_young_notify()

When the MM_WALK capability is enabled, memory that is mostly accessed by
a VM appears younger than it really is, therefore this memory will be less
likely to be evicted.  Therefore, the presence of a running VM can
significantly increase swap-outs for non-VM memory, regressing the
performance for the rest of the system.

Fix this regression by always calling {ptep,pmdp}_clear_young_notify()
whenever we clear the young bits on PMDs/PTEs.
