Pull irq fixes from Thomas Gleixner:
- Fix an off-by-one error in the failure path of msi_domain_alloc(),
which causes the cleanup loop to terminate early and leaking the
first allocated interrupt.
- Handle a corner case in GIC-V4 versus a lazily mapped Virtual
Processing Element (VPE). If the VPE has not been mapped because the
guest has not yet emitted a mapping command, then the set_affinity()
callback returns an error code, which causes the vCPU management to
fail.
Return success in this case without touching the hardware. This will
be done later when the guest issues the mapping command.

The error path in t7xx_dpmaif_rx_buf_alloc(), free and unmap the already
allocated and mapped skb in a loop, but the loop condition terminates when
the index reaches zero, which fails to free the first allocated skb at
index zero.
Check with i-- so that skb at index 0 is freed as well.

When building a 64-bit kernel on a 32-bit build host, incorrect
input MODULE_ALIAS() entries may be generated.
For example, when compiling a 64-bit kernel with CONFIG_INPUT_MOUSEDEV=m
on a 64-bit build machine, you will get the correct output:
$ grep MODULE_ALIAS drivers/input/mousedev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*110,*r*0,*1,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*r*8,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*14A,*r*a*0,*1,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*145,*r*a*0,*1,*18,*1C,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*110,*r*a*0,*1,*m*l*s*f*w*");
However, building the same kernel on a 32-bit machine results in
incorrect output:
$ grep MODULE_ALIAS drivers/input/mousedev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*110,*130,*r*0,*1,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*r*8,*a*m*l*s*f*w*");

MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*110,*130,*r*a*0,*1,*20,*21,*m*l*s*f*w*");
A similar issue occurs with CONFIG_INPUT_JOYDEV=m. On a 64-bit build
machine, the output is:
$ grep MODULE_ALIAS drivers/input/joydev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*0,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*2,*m*l*s*f*w*");

MODULE_ALIAS("input:b*v*p*e*-e*1,*k*2C0,*r*a*m*l*s*f*w*");
However, on a 32-bit machine, the output is incorrect:

When building a 64-bit kernel, BITS_PER_LONG is defined as 64. However,
on a 32-bit build machine, the constant 1L is a signed 32-bit value.
Left-shifting it beyond 32 bits causes wraparound, and shifting by 31
or 63 bits makes it a negative value.
The fix in commit e0e92632715f ("[PATCH] PATCH: 1 line 2.6.18 bugfix:
modpost-64bit-fix.patch") is incorrect; it only addresses cases where
a 64-bit kernel is built on a 64-bit build machine, overlooking cases
on a 32-bit build machine.
Using 1ULL ensures a 64-bit width on both 32-bit and 64-bit machines,
avoiding the wraparound issue.

When CONFIG_SATA_AHCI_PLATFORM=m, modpost outputs incorect acpi
MODULE_ALIAS() if the endianness of the target and the build machine
do not match.
When the endianness of the target kernel and the build machine match,
the output is correct:
$ grep 'MODULE_ALIAS("acpi' drivers/ata/ahci_platform.mod.c
MODULE_ALIAS("acpi*:APMC0D33:*");
MODULE_ALIAS("acpi*:010601:*");
However, when building a little-endian kernel on a big-endian machine
(or vice versa), the output is incorrect:
$ grep 'MODULE_ALIAS("acpi' drivers/ata/ahci_platform.mod.c
MODULE_ALIAS("acpi*:APMC0D33:*");
MODULE_ALIAS("acpi*:0601??:*");
The 'cls' and 'cls_msk' fields are 32-bit.
DEF_FIELD() must be used instead of DEF_FIELD_ADDR() to correctly handle
endianness of these 32-bit fields.
The check 'if (cls)' was unnecessary; it never became NULL, as it was
the pointer to 'symval' plus the offset to the 'cls' field.

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.

We have two reports of failed memory allocation in btrfs' code which is
calling into report zones.
Both of these reports have the following signature coming from
__vmalloc_area_node():
kworker/u17:5: vmalloc error: size 0, failed to allocate pages, mode:0x10dc2(GFP_KERNEL|__GFP_HIGHMEM|__GFP_NORETRY|__GFP_ZERO), nodemask=(null),cpuset=/,mems_allowed=0
Further debugging showed these where allocations of one sector (512
bytes) and at least one of the reporter's systems where low on memory,
so going through the overhead of allocating a vm area failed.
Switching the allocation from __vmalloc() to kvzalloc() avoids the
overhead of vmalloc() on small allocations and succeeds.
Note: the buffer is already freed using kvfree() so there's no need to
adjust the free path.

Pull cxl fixes from Ira Weiny:
"The bulk of these fixes center around an initialization order bug
reported by Gregory Price and some additional fall out from the
debugging effort.
In summary, cxl_acpi and cxl_mem race and previously worked because of
a bus_rescan_devices() while testing without modules built in.
Unfortunately with modules built in the rescan would fail due to the
cxl_port driver being registered late via the build order. Furthermore
it was found bus_rescan_devices() did not guarantee a probe barrier
which CXL was expecting. Additional fixes to cxl-test and decoder
allocation came along as they were found in this debugging effort.
The other fixes are pretty minor but one affects trace point data seen
by user space.
Summary:
- Fix crashes when running with cxl-test code

Pull bcachefs fixes from Kent Overstreet:
"Various syzbot fixes, and the more notable ones:
- Fix for pointers in an extent overflowing the max (16) on a
filesystem with many devices: we were creating too many cached
copies when moving data around. Now, we only create at most one
cached copy if there's a promote target set.
Caching will be a bit broken for reflinked data until 6.13: I have
larger series queued up which significantly improves the plumbing
for data options down into the extent (bch_extent_rebalance) to fix
this.
- Fix for deadlock on -ENOSPC on tiny filesystems
Allocation from the partial open_bucket list wasn't correctly
accounting partial open_buckets as free: this fixes the main cause
of tests timing out in the automated tests"

qcom/qdsp6 want to use irregular rtd->id because of its topology.

Let's calculate and save it to rtd at snd_soc_add_pcm_runtime()

But, this feature should be implemented by using "dai_link" instead

Current rtd has "num". It sounds/looks like size of rtd or something,
but it will be mainly used at snd_pcm_new() as "device index".

Currently, RK809's BUCK3 regulator is modelled in the driver as a
configurable regulator with 0.5-2.4V voltage range. But the voltage
setting is not actually applied, because when bit 6 of
PMIC_POWER_CONFIG register is set to 0 (default), BUCK3 output voltage
is determined by the external feedback resistor. Fix this, by setting
bit 6 when voltage selection is set. Existing users which do not
specify voltage constraints in their device trees will not be affected
by this change, since no voltage setting is applied in those cases,
and bit 6 is not enabled.

Commit 78ff64081949 ("vfs: Convert tracefs to use the new mount API")
converted tracefs to use the new mount APIs caused mount options
(e.g. gid=<gid>) to not take effect.
The tracefs superblock can be updated from multiple paths:
- on fs_initcall() to init_trace_printk_function_export()
- from a work queue to initialize eventfs
tracer_init_tracefs_work_func()
- fsconfig() syscall to mount or remount of tracefs
The tracefs superblock root inode gets created early on in
init_trace_printk_function_export().
With the new mount API, tracefs effectively uses get_tree_single() instead
of the old API mount_single().
Previously, mount_single() ensured that the options are always applied to
the superblock root inode:
(1) If the root inode didn't exist, call fill_super() to create it
and apply the options.
(2) If the root inode exists, call reconfigure_single() which
effectively calls tracefs_apply_options() to parse and apply
options to the subperblock's fs_info and inode and remount
eventfs (if necessary)
On the other hand, get_tree_single() effectively calls vfs_get_super()
which:
(3) If the root inode doesn't exists, calls fill_super() to create it
and apply the options.
(4) If the root inode already exists, updates the fs_context root
with the superblock's root inode.
(4) above is always the case for tracefs mounts, since the super block's
root inode will already be created by init_trace_printk_function_export().
This means that the mount options get ignored:
- Since it isn't applied to the superblock's root inode, it doesn't
get inherited by the children.
- Since eventfs is initialized from a separate work queue and
before call to mount with the options, and it doesn't get remounted
for mount.
Ensure that the mount options are applied to the super block and eventfs
is remounted to respect the mount options.
To understand this better, if fstab has the following:
tracefs /sys/kernel/tracing tracefs nosuid,nodev,noexec,gid=tracing 0 0
On boot up, permissions look like:
# ls -l /sys/kernel/tracing/trace
-rw-r----- 1 root root 0 Nov 1 08:37 /sys/kernel/tracing/trace
When it should look like:
# ls -l /sys/kernel/tracing/trace
-rw-r----- 1 root tracing 0 Nov 1 08:37 /sys/kernel/tracing/trace

Since commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP
boundaries") a mmap() of anonymous memory without a specific address hint
and of at least PMD_SIZE will be aligned to PMD so that it can benefit
from a THP backing page.
However this change has been shown to regress some workloads
significantly. [1] reports regressions in various spec benchmarks, with
up to 600% slowdown of the cactusBSSN benchmark on some platforms. The
benchmark seems to create many mappings of 4632kB, which would have merged
to a large THP-backed area before commit efa7df3e3bb5 and now they are
fragmented to multiple areas each aligned to PMD boundary with gaps
between. The regression then seems to be caused mainly due to the
benchmark's memory access pattern suffering from TLB or cache aliasing due
to the aligned boundaries of the individual areas.
Another known regression bisected to commit efa7df3e3bb5 is darktable [2]
[3] and early testing suggests this patch fixes the regression there as
well.
To fix the regression but still try to benefit from THP-friendly anonymous
mapping alignment, add a condition that the size of the mapping must be a
multiple of PMD size instead of at least PMD size. In case of many
odd-sized mapping like the cactusBSSN creates, those will stop being
aligned and with gaps between, and instead naturally merge again.
