commit cc4cffc3c142d57df48c07851862444e1d33bdaa upstream.
Add SDIO ids for use with the muRata 1YN (Cypress CYW43439).
The odd thing about this is that the previous 1YN populated
on M.2 card for evaluation purposes had BRCM SDIO vendor ID,
while the chip populated on real hardware has a Cypress one.
The device ID also differs between the two devices. But they
are both 43439 otherwise, so add the IDs for both.
On-device 1YN (43439), the new one, chip label reads "1YN":
```
/sys/.../mmc_host/mmc2/mmc2:0001 # cat vendor device
0x04b4
0xbd3d
```
EA M.2 evaluation board 1YN (43439), the old one, chip label reads "1YN ES1.4":
```
/sys/.../mmc_host/mmc0/mmc0:0001/# cat vendor device
0x02d0
0xa9a6
```

This reverts commit fe998a3c77b9f989a30a2a01fb00d3729a6d53a4.
Paul reports that it causes a regression with IB on CX4
and FW 12.18.1000. In addition I think that the concept
of "management PF" is not fully accepted and requires
a discussion.

Similarly to kmsan_vmap_pages_range_noflush(), kmsan_ioremap_page_range()
must also properly handle allocation/mapping failures. In the case of
such, it must clean up the already created metadata mappings and return an
error code, so that the error can be propagated to ioremap_page_range().
Without doing so, KMSAN may silently fail to bring the metadata for the
page range into a consistent state, which will result in user-visible
crashes when trying to access them.

As reported by Dipanjan Das, when KMSAN is used together with kernel fault
injection (or, generally, even without the latter), calls to kcalloc() or
__vmap_pages_range_noflush() may fail, leaving the metadata mappings for
the virtual mapping in an inconsistent state. When these metadata
mappings are accessed later, the kernel crashes.
To address the problem, we return a non-zero error code from
kmsan_vmap_pages_range_noflush() in the case of any allocation/mapping
failure inside it, and make vmap_pages_range_noflush() return an error if
KMSAN fails to allocate the metadata.
This patch also removes KMSAN_WARN_ON() from vmap_pages_range_noflush(),
as these allocation failures are not fatal anymore.

The RSS hash type specifies what portion of packet data NIC hardware used
when calculating RSS hash value. The RSS types are focused on Internet
traffic protocols at OSI layers L3 and L4. L2 (e.g. ARP) often get hash
value zero and no RSS type. For L3 focused on IPv4 vs. IPv6, and L4
primarily TCP vs UDP, but some hardware supports SCTP.
Hardware RSS types are differently encoded for each hardware NIC. Most
hardware represent RSS hash type as a number. Determining L3 vs L4 often
requires a mapping table as there often isn't a pattern or sorting
according to ISO layer.
The patch introduce a XDP RSS hash type (enum xdp_rss_hash_type) that
contains both BITs for the L3/L4 types, and combinations to be used by
drivers for their mapping tables. The enum xdp_rss_type_bits get exposed
to BPF via BTF, and it is up to the BPF-programmer to match using these
defines.
This proposal change the kfunc API bpf_xdp_metadata_rx_hash() adding
a pointer value argument for provide the RSS hash type.
Change signature for all xmo_rx_hash calls in drivers to make it compile.
The RSS type implementations for each driver comes as separate patches.

The commits referenced below allows userspace to use the NLM_F_ECHO flag
for RTM_NEW/DELLINK operations to receive unicast notifications for the
affected link. Prior to these changes, applications may have relied on
multicast notifications to learn the same information without specifying
the NLM_F_ECHO flag.
For such applications, the mentioned commits changed the behavior for
requests not using NLM_F_ECHO. Multicast notifications are still received,
but now use the portid of the requester and the sequence number of the
request instead of zero values used previously. For the application, this
message may be unexpected and likely handled as a response to the
NLM_F_ACKed request, especially if it uses the same socket to handle
requests and notifications.
To fix existing applications relying on the old notification behavior,
set the portid and sequence number in the notification only if the
request included the NLM_F_ECHO flag. This restores the old behavior
for applications not using it, but allows unicasted notifications for
others.

Pull compute express link (cxl) fixes from Dan Williams:
"Several fixes for driver startup regressions that landed during the
merge window as well as some older bugs.
The regressions were due to a lack of testing with what the CXL
specification calls Restricted CXL Host (RCH) topologies compared to
the testing with Virtual Host (VH) CXL topologies. A VH topology is
typical PCIe while RCH topologies map CXL endpoints as Root Complex
Integrated endpoints. The impact is some driver crashes on startup.
This merge window also added compatibility for range registers (the
mechanism that CXL 1.1 defined for mapping memory) to treat them like
HDM decoders (the mechanism that CXL 2.0 defined for mapping
Host-managed Device Memory). That work collided with the new region
enumeration code that was tested with CXL 2.0 setups, and fails with
crashes at startup.
Lastly, the DOE (Data Object Exchange) implementation for retrieving
an ACPI-like data table from CXL devices is being reworked for v6.4.
Several fixes fell out of that work that are suitable for v6.3.
All of this has been in linux-next for a while, and all reported
issues [1] have been addressed.
Summary:
- Fix several issues with region enumeration in RCH topologies that
can trigger crashes on driver startup or shutdown.
- Fix CXL DVSEC range register compatibility versus region
enumeration that leads to startup crashes
- Fix CDAT endiannes handling
- Fix multiple buffer handling boundary conditions
- Fix Data Object Exchange (DOE) workqueue usage vs

Recent attempt to ensure PREROUTING hook is executed again when a
decrypted ipsec packet received on a bridge passes through the network
stack a second time broke the physdev match in INPUT hook.
We can't discard the nf_bridge info strct from sabotage_in hook, as
this is needed by the physdev match.
Keep the struct around and handle this with another conditional instead.

Use the maple tree in RCU mode for VMA tracking.
The maple tree tracks the stack and is able to update the pivot
(lower/upper boundary) in-place to allow the page fault handler to write
to the tree while holding just the mmap read lock. This is safe as the
writes to the stack have a guard VMA which ensures there will always be a
NULL in the direction of the growth and thus will only update a pivot.
It is possible, but not recommended, to have VMAs that grow up/down
without guard VMAs. syzbot has constructed a testcase which sets up a VMA
to grow and consume the empty space. Overwriting the entire NULL entry
causes the tree to be altered in a way that is not safe for concurrent
readers; the readers may see a node being rewritten or one that does not
match the maple state they are using.
Enabling RCU mode allows the concurrent readers to see a stable node and
will return the expected result.

Pull tracing fixes from Steven Rostedt:
- Fix timerlat notification, as it was not triggering the notify to
users when a new max latency was hit.
- Do not trigger max latency if the tracing is off.
When tracing is off, the ring buffer is not updated, it does not make
sense to notify when there's a new max latency detected by the
tracer, as why that latency happened is not available. The tracing
logic still runs when the ring buffer is disabled, but it should not
be triggering notifications.
- Fix race on freeing the synthetic event "last_cmd" variable by adding
a mutex around it.
- Fix race between reader and writer of the ring buffer by adding
memory barriers. When the writer is still on the reader page it must
have its content visible on the buffer before it moves the commit
index that the reader uses to know how much content is on the page.
- Make get_lock_parent_ip() always inlined, as it uses _THIS_IP_ and
_RET_IP_, which gets broken if it is not inlined.
- Make __field(int, arr[5]) in a TRACE_EVENT() macro fail to build.
The field formats of trace events are calculated by using
sizeof(type) and other means by what is passed into the structure
macros like __field(). The __field() macro is only meant for atom
types like int, long, short, pointer, etc. It is not meant for
arrays.
The code will currently compile with arrays, but then the format
produced will be inaccurate, and user space parsing tools will break.
Two bugs have already been fixed, now add code that will make the
kernel fail to build if another trace event includes this buggy field
format.
- Fix boot up snapshot code:
Boot snapshots were triggering when not even asked for on the kernel
command line. This was caused by two bugs:
1) It would trigger a snapshot on any instance if one was created
from the kernel command line.
2) The error handling would only affect the top level instance.
So the fact that a snapshot was done on a instance that didn't
allocate a buffer triggered a warning written into the top level
buffer, and worse yet, disabled the top level buffer.
- Fix memory leak that was caused when an error was logged in a trace
buffer instance, and then the buffer instance was removed.
The allocated error log messages still needed to be freed.

The synchronize_rcu() will be invoked in the perf_pmu_migrate_context(),
when migrating a PMU to a new CPU. However, the current for_each_iommu()
is within RCU read-side critical section.
Two methods were considered to fix the issue.
- Use the dmar_global_lock to replace the RCU read lock when going
through the drhd list. But it triggers a lockdep warning.
- Use the cpuhp_setup_state_multi() to set up a dedicated state for each
IOMMU PMU. The lock can be avoided.
The latter method is implemented in this patch. Since each IOMMU PMU has
a dedicated state, add cpuhp_node and cpu in struct iommu_pmu to track
the state. The state can be dynamically allocated now. Remove the
CPUHP_AP_PERF_X86_IOMMU_PERF_ONLINE.

KVM irqfd based emulation of level-triggered interrupts doesn't work
quite correctly in some cases, particularly in the case of interrupts
that are handled in a Linux guest as oneshot interrupts (IRQF_ONESHOT).
Such an interrupt is acked to the device in its threaded irq handler,
i.e. later than it is acked to the interrupt controller (EOI at the end
of hardirq), not earlier.
Linux keeps such interrupt masked until its threaded handler finishes,
to prevent the EOI from re-asserting an unacknowledged interrupt.
However, with KVM + vfio (or whatever is listening on the resamplefd)
we always notify resamplefd at the EOI, so vfio prematurely unmasks the
host physical IRQ, thus a new physical interrupt is fired in the host.
This extra interrupt in the host is not a problem per se. The problem is
that it is unconditionally queued for injection into the guest, so the
guest sees an extra bogus interrupt. [*]
There are observed at least 2 user-visible issues caused by those
extra erroneous interrupts for a oneshot irq in the guest:
1. System suspend aborted due to a pending wakeup interrupt from
ChromeOS EC (drivers/platform/chrome/cros_ec.c).
2. Annoying "invalid report id data" errors from ELAN0000 touchpad
(drivers/input/mouse/elan_i2c_core.c), flooding the guest dmesg
every time the touchpad is touched.
The core issue here is that by the time when the guest unmasks the IRQ,
the physical IRQ line is no longer asserted (since the guest has
acked the interrupt to the device in the meantime), yet we
unconditionally inject the interrupt queued into the guest by the
previous resampling. So to fix the issue, we need a way to detect that
the IRQ is no longer pending, and cancel the queued interrupt in this
case.
With IOAPIC we are not able to probe the physical IRQ line state
directly (at least not if the underlying physical interrupt controller
is an IOAPIC too), so in this patch we use irqfd resampler for that.
Namely, instead of injecting the queued interrupt, we just notify the
resampler that this interrupt is done. If the IRQ line is actually
already deasserted, we are done. If it is still asserted, a new
interrupt will be shortly triggered through irqfd and injected into the
guest.
In the case if there is no irqfd resampler registered for this IRQ, we
cannot fix the issue, so we keep the existing behavior: immediately
unconditionally inject the queued interrupt.
This patch fixes the issue for x86 IOAPIC only. In the long run, we can
fix it for other irqchips and other architectures too, possibly taking
advantage of reading the physical state of the IRQ line, which is
possible with some other irqchips (e.g. with arm64 GIC, maybe even with
the legacy x86 PIC).
[*] In this description we assume that the interrupt is a physical host
interrupt forwarded to the guest e.g. by vfio. Potentially the same
issue may occur also with a purely virtual interrupt from an
emulated device, e.g. if the guest handles this interrupt, again, as
a oneshot interrupt.

It is useful to be able to do read-only traversal of the list of all the
registered irqfd resamplers without locking the resampler_lock mutex.
In particular, we are going to traverse it to search for a resampler
registered for the given irq of an irqchip, and that will be done with
an irqchip spinlock (ioapic->lock) held, so it is undesirable to lock a
mutex in this context. So turn this list into an RCU list.
For protecting the read side, reuse kvm->irq_srcu which is already used
for protecting a number of irq related things (kvm->irq_routing,
irqfd->resampler->list, kvm->irq_ack_notifier_list,
kvm->arch.mask_notifier_list).

Pull xfs percpu counter fixes from Darrick Wong:
"We discovered a filesystem summary counter corruption problem that was
traced to cpu hot-remove racing with the call to percpu_counter_sum
that sets the free block count in the superblock when writing it to
disk. The root cause is that percpu_counter_sum doesn't cull from
dying cpus and hence misses those counter values if the cpu shutdown
hooks have not yet run to merge the values.
I'm hoping this is a fairly painless fix to the problem, since the
dying cpu mask should generally be empty. It's been in for-next for a
week without any complaints from the bots.

Introduce a core thermal API function, thermal_cooling_device_update(),
for updating the max_state value for a cooling device and rearranging
its statistics in sysfs after a possible change of its ->get_max_state()
callback return value.
That callback is now invoked only once, during cooling device
registration, to populate the max_state field in the cooling device
object, so if its return value changes, it needs to be invoked again
and the new return value needs to be stored as max_state. Moreover,
the statistics presented in sysfs need to be rearranged in general,
because there may not be enough room in them to store data for all
of the possible states (in the case when max_state grows).
The new function takes care of that (and some other minor things
related to it), but some extra locking and lockdep annotations are
added in several places too to protect against crashes in the cases
when the statistics are not present or when a stale max_state value
might be used by sysfs attributes.
Note that the actual user of the new function will be added separately.

The FEI field of C2HTermReq/H2CTermReq is 4 bytes but not 4-byte-aligned
in the NVMe/TCP specification (it is located at offset 10 in the PDU).
Split it into two 16-bit integers in struct nvme_tcp_term_pdu
so no padding is inserted. There should also be 10 reserved bytes after.
There are currently no users of this type.

The CDAT exposed in sysfs differs between little endian and big endian
arches: On big endian, every 4 bytes are byte-swapped.
PCI Configuration Space is little endian (PCI r3.0 sec 6.1). Accessors
such as pci_read_config_dword() implicitly swap bytes on big endian.
That way, the macros in include/uapi/linux/pci_regs.h work regardless of
the arch's endianness. For an example of implicit byte-swapping, see
ppc4xx_pciex_read_config(), which calls in_le32(), which uses lwbrx
(Load Word Byte-Reverse Indexed).
DOE Read/Write Data Mailbox Registers are unlike other registers in
Configuration Space in that they contain or receive a 4 byte portion of
an opaque byte stream (a "Data Object" per PCIe r6.0 sec 7.9.24.5f).
They need to be copied to or from the request/response buffer verbatim.
So amend pci_doe_send_req() and pci_doe_recv_resp() to undo the implicit
byte-swapping.
The CXL_DOE_TABLE_ACCESS_* and PCI_DOE_DATA_OBJECT_DISC_* macros assume
implicit byte-swapping. Byte-swap requests after constructing them with
those macros and byte-swap responses before parsing them.
Change the request and response type to __le32 to avoid sparse warnings.
Per a request from Jonathan, replace sizeof(u32) with sizeof(__le32) for
consistency.

__enter_from_user_mode() is triggering noinstr warnings with
CONFIG_DEBUG_PREEMPT due to its call of preempt_count_add() via
ct_state().
The preemption disable isn't needed as interrupts are already disabled.
And the context_tracking_enabled() check in ct_state() also isn't needed
as that's already being done by the CT_WARN_ON().
Just use __ct_state() instead.
Fixes the following warnings:
vmlinux.o: warning: objtool: enter_from_user_mode+0xba: call to preempt_count_add() leaves .noinstr.text section

percpu_counter_sum_all() is now redundant as the race condition it
was invented to handle is now dealt with by percpu_counter_sum()
directly and all users of percpu_counter_sum_all() have been
removed.
Remove it.
This effectively reverts the changes made in f689054aace2
("percpu_counter: add percpu_counter_sum_all interface") except for
the cpumask iteration that fixes percpu_counter_sum() made earlier
in this series.

Currently DMA address width is either read from a RO device register
or force set from the platform data. This breaks DMA when the host DMA
address width is <=32it but the device is >32bit.
Right now the driver may decide to use a 2nd DMA descriptor for
another buffer (happens in case of TSO xmit) assuming that 32bit
addressing is used due to platform configuration but the device will
still use both descriptor addresses as one address.
This can be observed with the Intel EHL platform driver that sets
32bit for addr64 but the MAC reports 40bit. The TX queue gets stuck in
case of TCP with iptables NAT configuration on TSO packets.
The logic should be like this: Whatever we do on the host side (memory
allocation GFP flags) should happen with the host DMA width, whenever
we decide how to set addresses on the device registers we must use the
device DMA address width.
This patch renames the platform address width field from addr64 (term
used in device datasheet) to host_addr and uses this value exclusively
for host side operations while all chip operations consider the device
DMA width as read from the device register.

Commit 8633ef82f101 ("drivers/firmware: consolidate EFI framebuffer setup
for all arches") moved the sysfb_apply_efi_quirks() call in sysfb_init()
from before the [sysfb_]parse_mode() call to after it.
But sysfb_apply_efi_quirks() modifies the global screen_info struct which
[sysfb_]parse_mode() parses, so doing it later is too late.
This has broken all DMI based quirks for correcting wrong firmware efifb
settings when simpledrm is used.
To fix this move the sysfb_apply_efi_quirks() call back to its old place
and split the new setup of the efifb_fwnode (which requires
the platform_device) into its own function and call that at
the place of the moved sysfb_apply_efi_quirks(pd) calls.
