Currently cfg80211 checks for invalid channels whenever there is a
regulatory update and stops the active interfaces if it is operating on
an unsupported channel in the new regulatory domain.
This is done based on a regulatory flag REGULATORY_IGNORE_STALE_KICKOFF
set during wiphy registration which disables this enforcement when
unsupported interface modes are supported by driver.
Add support to enable this enforcement when Mesh Point interface type
is advertised by drivers.

[cmllamas: fix trivial merge conflict according to 294e70c952]

There's currently only one driver that reports CHECKSUM_COMPLETE,
that is iwlwifi. The current hardware there calculates checksum
after the SNAP header, but only RFC 1042 (and some other cases,
but replicating the exact hardware logic for corner cases in the
driver seemed awkward.)
Newer generations of hardware will checksum _including_ the SNAP,
which makes things easier.
To handle that, simply always assume the checksum _includes_ the
SNAP header, which this patch does, requiring to first add it
for older iwlwifi hardware, and then remove it again later on
conversion.
Alternatively, we could have:
1) Always assumed the checksum starts _after_ the SNAP header;
the problem with this is that we'd have to replace the exact
"what is the SNAP" check in iwlwifi that cfg80211 has.
2) Made it configurable with some flag, but that seemed like too
much complexity.

Removed cfg80211.ko and mac80211.ko as vendor modules to use GKI
versions for virtual_device arm64 builds.
Remove symbols required for these modules from the symbol list;
so they stay protected for everyone until there is a proper case
for overriding these modules is required.

pkvm_iommu_s2mpu_init. Instead of being called implicitly from

This will allow IOMMU drivers to be loaded as EL2 modules
To achieve that, EL2 module init should register and init
the driver using pkvm_iommu_driver_init.
To avoid having to hardcode S2MPU drivers in IOMMU EL2 code,
pkvm_iommu_driver_init will have a ptr to driver struct instead of
id.
Id is removed from pkvm_iommu_driver and the address of the struct
is treated as the id of the driver, the kernel is expected to pass
linear mapping address of the driver and the hypervisor is expected
to use hyp address.

and can be refreshed. For standalone DFS root referrals it wouldn't
be a problem as the client ends up having an IPC tcon for both mount
and cache.

commit 44035ec2fd upstream.
There's been a very long running bug that seems to have been neglected for
a while, where amdgpu consistently triggers a KASAN error at start:
BUG: KASAN: global-out-of-bounds in read_indirect_azalia_reg+0x1d4/0x2a0 [amdgpu]
Read of size 4 at addr ffffffffc2274b28 by task modprobe/1889
After digging through amd's rather creative method for accessing registers,
I eventually discovered the problem likely has to do with the fact that on
my dce120 GPU there are supposedly 7 sets of audio registers. But we only
define a register mapping for 6 sets.
So, fix this and fix the KASAN warning finally.

commit 013c1c5585 upstream.
btrfs_ioctl_get_subvol_info() frees the search path after the userspace
copy from the temp buffer @subvol_info. This can lead to a lock splat
warning.
Fix this by freeing the path before we copy it to userspace.

commit c48c8b829d upstream.
Although setting the affinity of an interrupt to a set of CPUs that doesn't
have any online CPU is generally frowned apon, there are a few limited
cases where such affinity is set from a CPUHP notifier, setting the
affinity to a CPU that isn't online yet.
The saving grace is that this is always done using the 'force' attribute,
which gives a hint that the affinity setting can be outside of the online
CPU mask and the callsite set this flag with the knowledge that the
underlying interrupt controller knows to handle it.
This restores the expected behaviour on Marek's system.

commit 33de0aa4ba upstream.
[ Fixed small conflicts due to the HK_FLAG_MANAGED_IRQ flag been
renamed on upstream ]
When booting with maxcpus=<small number> (or even loading a driver
while most CPUs are offline), it is pretty easy to observe managed
affinities containing a mix of online and offline CPUs being passed
to the irqchip driver.
This means that the irqchip cannot trust the affinity passed down
from the core code, which is a bit annoying and requires (at least
in theory) all drivers to implement some sort of affinity narrowing.
In order to address this, always limit the cpumask to the set of
online CPUs.

commit d802057c7c upstream.
[ This commit is almost a rewrite because it conflicts with Thomas
Gleixner's refactoring of this code in v5.17-rc1. I wasn't sure if
I should drop all the s-o-bs (including Mark's), but decided
to keep as the original commit ]
When booting with maxcpus=<small number>, interrupt controllers
such as the GICv3 ITS may not be able to satisfy the affinity of
some managed interrupts, as some of the HW resources are simply
not available.
The same thing happens when loading a driver using managed interrupts
while CPUs are offline.
In order to deal with this, do not try to activate such interrupt
if there is no online CPU capable of handling it. Instead, place
it in shutdown state. Once a capable CPU shows up, it will be
activated.

commit 44361e8cf9 upstream.
file_modified() must be called with inode lock held. fuse_fallocate()
didn't lock the inode in case of just FALLOC_KEEP_SIZE flags value, which
resulted in a kernel Warning in notify_change().
Lock the inode unconditionally, like all other fallocate implementations
do.
