Pull timer migration updates from Thomas Gleixner:
"Fixes and minor updates for the timer migration code:
- Stop testing the group->parent pointer as it is not guaranteed to
be stable over a chain of operations by design.
This includes a warning which would be nice to have but it produces
false positives due to the racy nature of the check.
- Plug a race between CPUs going in and out of idle and a CPU hotplug
operation. The latter can create and connect a new hierarchy level
which is missed in the concurrent updates of CPUs which go into
idle. As a result the events of such a CPU might not be processed
and timers go stale.
Cure it by splitting the hotplug operation into a prepare and
online callback. The prepare callback is guaranteed to run on an
online and therefore active CPU. This CPU updates the hierarchy and
being online ensures that there is always at least one migrator
active which handles the modified hierarchy correctly when going
idle. The online callback which runs on the incoming CPU then just
marks the CPU active and brings it into operation.
- Improve tracing and polish the code further so it is more obvious
what's going on"

hostfs not keep the host directory when mounting. When the host
directory is none (default), fc->source is used as the host root
directory, and this is wrong. Here we use `parse_monolithic` to
handle the old mount path for parsing the root directory. For new
mount path, The `parse_param` is used for the host directory parse.

Christian noticed that it is possible for a privileged user to mount
most filesystems with a non-initial user namespace in sb->s_user_ns.
When fsopen() is called in a non-init namespace the caller's namespace
is recorded in fs_context->user_ns. If the returned file descriptor is
then passed to a process priviliged in init_user_ns, that process can
call fsconfig(fd_fs, FSCONFIG_CMD_CREATE), creating a new superblock
with sb->s_user_ns set to the namespace of the process which called
fsopen().
This is problematic. We cannot assume that any filesystem which does not
set FS_USERNS_MOUNT has been written with a non-initial s_user_ns in
mind, increasing the risk for bugs and security issues.
Prevent this by returning EPERM from sget_fc() when FS_USERNS_MOUNT is
not set for the filesystem and a non-initial user namespace will be
used. sget() does not need to be updated as it always uses the user
namespace of the current context, or the initial user namespace if
SB_SUBMOUNT is set.

In a commit 1d717123bb1a ("ALSA: firewire-lib: Avoid
-Wflex-array-member-not-at-end warning"), DEFINE_FLEX() macro was used to
handle variable length of array for header field in struct fw_iso_packet
structure. The usage of macro has a side effect that the designated
initializer assigns the count of array to the given field. Therefore
CIP_HEADER_QUADLETS (=2) is assigned to struct fw_iso_packet.header,
while the original designated initializer assigns zero to all fields.
With CIP_NO_HEADER flag, the change causes invalid length of header in
isochronous packet for 1394 OHCI IT context. This bug affects all of
devices supported by ALSA fireface driver; RME Fireface 400, 800, UCX, UFX,
and 802.
This commit fixes the bug by replacing it with the alternative version of
macro which corresponds no initializer.

This reverts commit d3155742db89df3b3c96da383c400e6ff4d23c25.
The header_length field is byte unit, thus it can not express the number of
elements in header field. It seems that the argument for counted_by
attribute can have no arithmetic expression, therefore this commit just
reverts the issued commit.

The minmax infrastructure is overkill for simple constants, and can
cause huge expansions because those simple constants are then used by
other things.
For example, 'pageblock_order' is a core VM constant, but because it was
implemented using 'min_t()' and all the type-checking that involves, it
actually expanded to something like 2.5kB of preprocessor noise.
And when that simple constant was then used inside other expansions:
#define pageblock_nr_pages (1UL << pageblock_order)
#define pageblock_start_pfn(pfn) ALIGN_DOWN((pfn), pageblock_nr_pages)
and we then use that inside a 'max()' macro:
case ISOLATE_SUCCESS:
update_cached = false;
last_migrated_pfn = max(cc->zone->zone_start_pfn,
pageblock_start_pfn(cc->migrate_pfn - 1));
the end result was that one statement expanding to 253kB in size.
There are probably other cases of this, but this one case certainly
stood out.
I've added 'MIN_T()' and 'MAX_T()' macros for this kind of "core simple
constant with specific type" use. These macros skip the type checking,
and as such need to be very sparingly used only for obvious cases that
have active issues like this.

We have some very fancy min/max macros that have tons of sanity checking
to warn about mixed signedness etc.
This is all things that a sane compiler should warn about, but there are
no sane compiler interfaces for this, and '-Wsign-compare' is broken [1]
and not useful.
So then we compensate (some would say over-compensate) by doing the
checks manually with some truly horrid macro games.
And no, we can't just use __builtin_types_compatible_p(), because the
whole question of "does it make sense to compare these two values" is a
lot more complicated than that.
For example, it makes a ton of sense to compare unsigned values with
simple constants like "5", even if that is indeed a signed type. So we
have these very strange macros to try to make sensible type checking
decisions on the arguments to 'min()' and 'max()'.
But that can cause enormous code expansion if the min()/max() macros are
used with complicated expressions, and particularly if you nest these
things so that you get the first big expansion then expanded again.
The xen setup.c file ended up ballooning to over 50MB of preprocessed
noise that takes 15s to compile (obviously depending on the build host),
largely due to one single line.
So let's split that one single line to just be simpler. I think it ends
up being more legible to humans too at the same time. Now that single
file compiles in under a second.

Syzbot reported that a buffer state inconsistency was detected in
nilfs_btnode_create_block(), triggering a kernel bug.
It is not appropriate to treat this inconsistency as a bug; it can occur
if the argument block address (the buffer index of the newly created
block) is a virtual block number and has been reallocated due to
corruption of the bitmap used to manage its allocation state.
So, modify nilfs_btnode_create_block() and its callers to treat it as a
possible filesystem error, rather than triggering a kernel bug.

__rmqueue_pcplist()
It's expected that no page should be left in pcp_list after calling
zone_pcp_disable() in offline_pages(). Previously, it's observed that
offline_pages() gets stuck [1] due to some pages remaining in pcp_list.
Cause:
There is a race condition between drain_pages_zone() and __rmqueue_pcplist()
involving the pcp->count variable. See below scenario:
CPU0 CPU1
---------------- ---------------
spin_lock(&pcp->lock);
__rmqueue_pcplist() {
zone_pcp_disable() {
/* list is empty */
if (list_empty(list)) {
/* add pages to pcp_list */
alloced = rmqueue_bulk()
mutex_lock(&pcp_batch_high_lock)
...
__drain_all_pages() {
drain_pages_zone() {
/* read pcp->count, it's 0 here */
count = READ_ONCE(pcp->count)
/* 0 means nothing to drain */
/* update pcp->count */
pcp->count += alloced << order;
...
...
spin_unlock(&pcp->lock);
In this case, after calling zone_pcp_disable() though, there are still some
pages in pcp_list. And these pages in pcp_list are neither movable nor
isolated, offline_pages() gets stuck as a result.
Solution:
Expand the scope of the pcp->lock to also protect pcp->count in
drain_pages_zone(), to ensure no pages are left in the pcp list after
zone_pcp_disable()

Oliver Sand reported a performance regression caused by commit
98c9daf5ae6b ("mm: memcg: guard memcg1-specific members of struct
mem_cgroup_per_node"), which puts some fields of the mem_cgroup_per_node
structure under the CONFIG_MEMCG_V1 config option. Apparently it causes a
false cache sharing between lruvec and lru_zone_size members of the
structure. Fix it by adding an explicit padding after the lruvec member.
Even though the padding is not required with CONFIG_MEMCG_V1 set, it seems
like the introduced memory overhead is not significant enough to warrant
another divergence in the mem_cgroup_per_node layout, so the padding is
added unconditionally.

Outline and export free_reserved_page() because modules use it and it in
turn uses page_ext_{get|put} which should not be exported. The same
result could be obtained by outlining {get|put}_page_tag_ref() but that
would have higher performance impact as these functions are used in more
performance critical paths.

The decompression code parses a huffman tree and counts the number of
symbols for a given bit length. In rare cases, there may be >= 256
symbols with a given bit length, causing the unsigned char to overflow.
This causes a decompression failure later when the code tries and fails to
find the bit length for a given symbol.
Since the maximum number of symbols is 258, use unsigned short instead.

xarray can't support arbitrary page cache size. the largest and supported
page cache size is defined as MAX_PAGECACHE_ORDER by commit 099d90642a71
("mm/filemap: make MAX_PAGECACHE_ORDER acceptable to xarray"). However,
it's possible to have 512MB page cache in the huge memory's collapsing
path on ARM64 system whose base page size is 64KB. 512MB page cache is
breaking the limitation and a warning is raised when the xarray entry is
split as shown in the following example.

Fix it by correcting the supported page cache orders, different sets for

disallowed on all non-DAX files on ARM64 system where the base page size
is 64KB. After this patch is applied, the test program fails with error

Commit 3bd786f76de2 ("mm: convert do_set_pte() to set_pte_range()")
replaced do_set_pte() with set_pte_range() and that introduced a
regression in the following faulting path of non-anonymous vmas which
caused the PTE for the faulting address to be marked as old instead of
young.
handle_pte_fault()
do_pte_missing()
do_fault()
do_read_fault() || do_cow_fault() || do_shared_fault()
finish_fault()
set_pte_range()
The polarity of prefault calculation is incorrect. This leads to prefault
being incorrectly set for the faulting address. The following check will
incorrectly mark the PTE old rather than young. On some architectures
this will cause a double fault to mark it young when the access is
retried.
if (prefault && arch_wants_old_prefaulted_pte())
entry = pte_mkold(entry);
On a subsequent fault on the same address, the faulting path will see a
non NULL vmf->pte and instead of reaching the do_pte_missing() path, PTE
will then be correctly marked young in handle_pte_fault() itself.
Due to this bug, performance degradation in the fault handling path will
be observed due to unnecessary double faulting.

Allows users to read Intel PMT (Platform Monitoring Technology)

necessary vm_layout struct with EXPORT_SYMBOL to prevent linkage
problems
- Fix an endless loop in the CF_DIAG event stop in the CPU Measurement
Counter Facility code when the counter set size is zero
- Remove the PROTECTED_VIRTUALIZATION_GUEST config option and enable
its functionality by default
- Support allocation of multiple MSI interrupts per device and improve
logging of architecture-specific limitations
- Add support for lowcore relocation as a debugging feature to catch
all null ptr dereferences in the kernel address space, improving
detection beyond the current implementation's limited write access
protection
- Clean up and rework CPU alternatives to allow for callbacks and early
patching for the lowcore relocation

Printing information about the source and value during initialization and
reading of the counter for each cpu, while useful when debugging,
results in too verbose output.

This leaves the stdout cleaner, having only counter data. It makes it
easier for programs to parse the output of turbostat, for example
selftests.

Pull arm64 fixes from Will Deacon:
"The usual summary below, but the main fix is for the fast GUP lockless
page-table walk when we have a combination of compile-time and
run-time folding of the p4d and the pud respectively.
- Remove some redundant Kconfig conditionals
- Fix string output in ptrace selftest
- Fix fast GUP crashes in some page-table configurations
- Remove obsolete linker option when building the vDSO
- Fix some sysreg field definitions for the GIC"

There are cases where services need to remount (or change their
credentials files) when keys have expired, but it can be helpful
to have a dynamic trace point to make it easier to notify the
service to refresh the storage account key.
Here is sample output, one from mount with bad password, one
from a reconnect where the password has been changed or expired
and reconnect fails (requiring remount with new storage account key)
