efdaa61d73 drivers/xen/xenbus: remove quirk for Xen 3.x
The kernel is not supported to run as a Xen guest on Xen versions
older than 4.0.

Remove xen_strict_xenbus_quirk() which is testing the Xen version to be
at least 4.0.

8151320c74 ACPI: pfr_update: Fix the driver update version check
The security-version-number check should be used rather
than the runtime version check for driver updates.

Otherwise, the firmware update would fail when the update binary had
a lower runtime version number than the current one.

edede7a6dc trace/fgraph: Fix the warning caused by missing unregister notifier
This warning was triggered during testing on v6.16:

When writing to the function_profile_enabled interface, the notifier was
not unregistered after start_graph_tracing failed, causing a warning the

Fixed by adding unregister_pm_notifier in the exception path.

6a909ea83f tracing: Limit access to parser->buffer when trace_get_user failed
When the length of the string written to set_ftrace_filter exceeds
FTRACE_BUFF_MAX, the following KASAN alarm will be triggered:

BUG: KASAN: slab-out-of-bounds in strsep+0x18c/0x1b0

The reason is that trace_get_user will fail when processing a string
longer than FTRACE_BUFF_MAX, but not set the end of parser->buffer to 0.
Then an OOB access will be triggered in ftrace_regex_release->
ftrace_process_regex->strsep->strpbrk. We can solve this problem by
limiting access to parser->buffer when trace_get_user failed.

b5bbbb70e5 s390/bpf: Use direct calls and jumps where possible
After the V!=R rework (commit c98d2ecae0 ("s390/mm: Uncouple physical
vs virtual address spaces")), all kernel code and related data are
allocated within a 4G region, making it possible to use relative
addressing in BPF code more extensively.

Convert as many indirect calls and jumps to direct calls as possible,
namely:

* BPF_CALL
* __bpf_tramp_enter()
* __bpf_tramp_exit()
* __bpf_prog_enter()
* __bpf_prog_exit()
* fentry
* fmod_ret
* fexit
* BPF_TRAMP_F_CALL_ORIG without BPF_TRAMP_F_ORIG_STACK
* Trampoline returns without BPF_TRAMP_F_SKIP_FRAME and
  BPF_TRAMP_F_ORIG_STACK

The following indirect calls and jumps remain:

* Prog returns
* Trampoline returns with BPF_TRAMP_F_SKIP_FRAME or
  BPF_TRAMP_F_ORIG_STACK
* BPF_TAIL_CALL
* BPF_TRAMP_F_CALL_ORIG with BPF_TRAMP_F_ORIG_STACK

As a result, only one usage of call_r1() remains, so inline it.

456010c8b9 netfilter: nft_set_pipapo: Use nested-BH locking for nft_pipapo_scratch
nft_pipapo_scratch is a per-CPU variable and relies on disabled BH for
its locking. Without per-CPU locking in local_bh_disable() on PREEMPT_RT
this data structure requires explicit locking.

Add a local_lock_t to the data structure and use local_lock_nested_bh() for
locking. This change adds only lockdep coverage and does not alter the
functional behaviour for !PREEMPT_RT.

6aa67d5706 netfilter: nft_set_pipapo: Store real pointer, adjust later.
The struct nft_pipapo_scratch is allocated, then aligned to the required
alignment and difference (in bytes) is then saved in align_off. The
aligned pointer is used later.
While this works, it gets complicated with all the extra checks if
all member before map are larger than the required alignment.

Instead of saving the aligned pointer, just save the returned pointer
and align the map pointer in nft_pipapo_lookup() before using it. The
alignment later on shouldn't be that expensive. With this change, the
align_off can be removed and the pointer can be passed to kfree() as is.

84c1da7b38 netfilter: nft_set_pipapo: use avx2 algorithm for insertions too
Always prefer the avx2 implementation if its available.
This greatly improves insertion performance (each insertion
checks if the new element would overlap with an existing one):

time nft -f - <<EOF
table ip pipapo {
	set s {
		typeof ip saddr . tcp dport
		flags interval
		size 800000
		elements = { 10.1.1.1 - 10.1.1.4 . 3996,
[.. 800k entries elided .. ]

before:
real    1m55.993s
user    0m2.505s
sys     1m53.296s

after:
real    0m42.586s
user    0m2.554s
sys     0m39.811s

Fold patch from Sebastian:

kernel_fpu_begin_mask()/ _end() remains in pipapo_get_avx2() where it is
required.

A followup patch will add local_lock_t to struct nft_pipapo_scratch in
order to protect the map pointer. The lock can not be acquired in
preemption disabled context which is what kernel_fpu_begin*() does.

block: don't silently ignore metadata for sync read/write
The block fops don't try to handle metadata for synchronous requests,
probably because the completion handler looks at dio->iocb which is not
valid for synchronous requests.

But silently ignoring metadata (or warning in case of
__blkdev_direct_IO_simple) is a really bad idea as that can cause
silent data corruption if a user ever shows up.

Instead simply handle metadata for synchronous requests as the completion
handler can simply check for bio_integrity() as the block layer default
integrity will already be freed at this point, and thus bio_integrity()
will only return true for user mapped integrity.

arch/powerpc/kernel/kvm.c:646:9: warning: switch with no cases

Currently #ifdef were added after the switch case which are specific
for BOOKE and PPC_BOOK3S_32. These are not enabled in pseries/powernv
defconfig. Fix it by moving the #ifdef before switch(){}

6a859f1a19 powerpc: unify two CONFIG_POWERPC64_CPU entries in the same choice block
There are two CONFIG_POWERPC64_CPU entries in the "CPU selection"
choice block.

I guess the intent is to display a different prompt depending on
CPU_LITTLE_ENDIAN: "Generic (POWER5 and PowerPC 970 and above)" for big
endian, and "Generic (POWER8 and above)" for little endian.

I stumbled on this tricky use case, and worked around it on Kconfig with
commit 4d46b5b623 ("kconfig: fix infinite loop in sym_calc_choice()").
However, I doubt that supporting multiple entries with the same symbol
in a choice block is worth the complexity - this is the only such case
in the kernel tree.

This commit merges the two entries. Once this cleanup is accepted in
the powerpc subsystem, I will proceed to refactor the Kconfig parser.

eb59d4c594 powerpc: use always-y instead of extra-y in Makefiles
The extra-y syntax is planned for deprecation because it is similar
to always-y.

When building the boot wrapper, always-y and extra-y are equivalent.
Use always-y instead.

In arch/powerpc/kernel/Makefile, I added ifdef KBUILD_BUILTIN to
keep the current behavior: prom_init_check is skipped when building
only modular objects.

Until commit 6c85f52b10 ("kvm/ppc: IRQ disabling cleanup"),
kvmppc_prepare_to_enter() was called with interrupts already disabled by
the caller, which was documented in the comment above the function.

Post-cleanup, the function is now called with interrupts enabled, and
disables interrupts itself.

Fix the comment to reflect the current behaviour.
