53a563b01f KVM: arm64: Make the hyp memory pool static
The hyp memory pool struct is sized to fit exactly the needs of the
hypervisor stage-1 page-table allocator, so it is important it is not
used for anything else. As it is currently used only from setup.c,
reduce its visibility by marking it static.

a770ee80e6 KVM: arm64: pkvm: Disable GICv2 support
GICv2 requires having device mappings in guests and the hypervisor,
which is incompatible with the current pKVM EL2 page ownership model
which only covers memory. While it would be desirable to support pKVM
with GICv2, this will require a lot more work, so let's make the
current assumption clear until then.

34b43a8849 KVM: arm64: pkvm: Fix hyp_pool max order
The EL2 page allocator in protected mode maintains a per-pool max order
value to optimize allocations when the memory region it covers is small.
However, the max order value is currently under-estimated whenever the
number of pages in the region is a power of two. Fix the estimation.

ASoC: SOF: OF: Avoid reverse module dependency
Similar with commit 8a49cd11e6 ("ASoC: SOF: ACPI: avoid reverse

link against a common "helper" framework.

sof-of-dev.c becomes a library with the interface defined in the newly

2f5b3514c3 x86/boot: Move EFI range reservation after cmdline parsing
The memory reservation in arch/x86/platform/efi/efi.c depends on at
least two command line parameters. Put it back later in the boot process
and move efi_memblock_x86_reserve_range() out of early_memory_reserve().

An attempt to fix this was done in

  8d48bf8206 ("x86/boot: Pull up cmdline preparation and early param parsing")

but that caused other troubles so it got reverted.

The bug this is addressing is:

Dan reports that Anjaneya Chagam can no longer use the efi=nosoftreserve
kernel command line parameter to suppress "soft reservation" behavior.

This is due to the fact that the following call-chain happens at boot:

  early_reserve_memory
  |-> efi_memblock_x86_reserve_range
      |-> efi_fake_memmap_early

which does

        if (!efi_soft_reserve_enabled())
                return;

and that would have set EFI_MEM_NO_SOFT_RESERVE after having parsed
"nosoftreserve".

However, parse_early_param() gets called *after* it, leading to the boot
cmdline not being taken into account.

e54183fa70 fsnotify: generate FS_RENAME event with rich information
The dnotify FS_DN_RENAME event is used to request notification about
a move within the same parent directory and was always coupled with
the FS_MOVED_FROM event.

Rename the FS_DN_RENAME event flag to FS_RENAME, decouple it from
FS_MOVED_FROM and report it with the moved dentry instead of the moved
inode, so it has the information about both old and new parent and name.

Generate the FS_RENAME event regardless of same parent dir and apply
the "same parent" rule in the generic fsnotify_handle_event() helper
that is used to call backends with ->handle_inode_event() method
(i.e. dnotify).  The ->handle_inode_event() method is not rich enough to
report both old and new parent and name anyway.

The enriched event is reported to fanotify over the ->handle_event()
method with the old and new dir inode marks in marks array slots for
ITER_TYPE_INODE and a new iter type slot ITER_TYPE_INODE2.

The enriched event will be used for reporting old and new parent+name to
fanotify groups with FAN_RENAME events.

d61fd650e9 fanotify: introduce group flag FAN_REPORT_TARGET_FID
FAN_REPORT_FID is ambiguous in that it reports the fid of the child for
some events and the fid of the parent for create/delete/move events.

The new FAN_REPORT_TARGET_FID flag is an implicit request to report
the fid of the target object of the operation (a.k.a the child inode)
also in create/delete/move events in addition to the fid of the parent
and the name of the child.

To reduce the test matrix for uninteresting use cases, the new
FAN_REPORT_TARGET_FID flag requires both FAN_REPORT_NAME and
FAN_REPORT_FID.  The convenience macro FAN_REPORT_DFID_NAME_TARGET
combines FAN_REPORT_TARGET_FID with all the required flags.

__pi_dcache_clean_poc() directly.

04e57a2d95 tomoyo: Check exceeded quota early in tomoyo_domain_quota_is_ok().
If tomoyo is used in a testing/fuzzing environment in learning mode,
for lots of domains the quota will be exceeded and stay exceeded
for prolonged periods of time. In such cases it's pointless (and slow)
to walk the whole acl list again and again just to rediscover that
the quota is exceeded. We already have the TOMOYO_DIF_QUOTA_WARNED flag
that notes the overflow condition. Check it early to avoid the slowdown.

[penguin-kernel]
This patch causes a user visible change that the learning mode will not be
automatically resumed after the quota is increased. To resume the learning
mode, administrator will need to explicitly clear TOMOYO_DIF_QUOTA_WARNED
flag after increasing the quota. But I think that this change is generally
preferable, for administrator likely wants to optimize the acl list for
that domain before increasing the quota, or that domain likely hits the
quota again. Therefore, don't try to care to clear TOMOYO_DIF_QUOTA_WARNED
flag automatically when the quota for that domain changed.

244a36e50d drm/vc4: kms: Wait for the commit before increasing our clock rate
Several DRM/KMS atomic commits can run in parallel if they affect
different CRTC. These commits share the global HVS state, so we have
some code to make sure we run commits in sequence. This synchronization
code is one of the first thing that runs in vc4_atomic_commit_tail().

Another constraints we have is that we need to make sure the HVS clock
gets a boost during the commit. That code relies on clk_set_min_rate and
will remove the old minimum and set a new one. We also need another,
temporary, minimum for the duration of the commit.

The algorithm is thus to set a temporary minimum, drop the previous
one, do the commit, and finally set the minimum for the current mode.

However, the part that sets the temporary minimum and drops the older
one runs before the commit synchronization code.

Thus, under the proper conditions, we can end up mixing up the minimums
and ending up with the wrong one for our current step.

To avoid it, let's move the clock setup in the protected section.

fbe6183998 Revert "x86/boot: Pull up cmdline preparation and early param parsing"
This reverts commit 8d48bf8206.

It turned out to be a bad idea as it broke supplying mem= cmdline
parameters due to parse_memopt() requiring preparatory work like setting
up the e820 table in e820__memory_setup() in order to be able to exclude
the range specified by mem=.

Pulling that up would've broken Xen PV again, see threads at

  https://lkml.kernel.org/r/20210920120421.29276-1-jgross@suse.com

due to xen_memory_setup() needing the first reservations in
early_reserve_memory() - kernel and initrd - to have happened already.

This could be fixed again by having Xen do those reservations itself...

Long story short, revert this and do a simpler fix in a later patch.

reference taken by ethnl_parse_header_dev_get().

92c959bae2 reset: renesas: Fix Runtime PM usage
If pm_runtime_resume_and_get() fails then it returns w/o the RPM usage
counter being incremented. In this case call pm_runtime_put() in
remove() will result in a usage counter imbalance. Therefore check the
return code of pm_runtime_resume_and_get() and bail out in case of error.

The commit f115f3c0d5 ("iommu/arm-smmu-v3: Decrease the queue size of
evtq and priq") decreases evtq and priq, which may lead evtq/priq to be
full with fault events, e.g HiSilicon ZIP/SEC/HPRE have maximum 1024 queues
in one device, every queue could be binded with one process and trigger a
fault event. So let's revert f115f3c0d5.

In fact, if an implementation of SMMU really does not need so long evtq
and priq, value of IDR1_EVTQS and IDR1_PRIQS can be set to proper ones.

d56a8e9c7a dt-bindings: soc: samsung: Fix I2C clocks order in USI binding example
Now that HSI2C binding [1] is converted to dt-schema format, it reveals
incorrect HSI2C clocks order in USI binding example:

    .../exynos-usi.example.dt.yaml:
    i2c@13820000: clock-names:0: 'hsi2c' was expected
    From schema: .../i2c-exynos5.yaml

    .../exynos-usi.example.dt.yaml:
    i2c@13820000: clock-names:1: 'hsi2c_pclk' was expected
    From schema: .../i2c-exynos5.yaml

Change HSI2C clock order in USI binding example to satisfy HSI2C binding
requirements and fix above warnings.

f97982398c libbpf: Avoid reading past ELF data section end when copying license
Fix possible read beyond ELF "license" data section if the license
string is not properly zero-terminated. Use the fact that libbpf_strlcpy
never accesses the (N-1)st byte of the source string because it's
replaced with '\0' anyways.

If this happens, it's a violation of contract between libbpf and a user,
but not handling this more robustly upsets CIFuzz, so given the fix is
trivial, let's fix the potential issue.
