8f69cba096 x86: Rename __{start,end}_init_task to __{start,end}_init_stack 
The stack of a task has been separated from the memory of a task_struct
struture for a long time on x86, as a result __{start,end}_init_task no
longer mark the start and end of the init_task structure, but its stack
only.

Rename __{start,end}_init_task to __{start,end}_init_stack.

Note other architectures are not affected because __{start,end}_init_task
are used on x86 only.

f8a6fc99c2 wifi: rtlwifi: drop WMM stubs from rtl8192cu 
Since WMM support was never actually implemented and related TODO is
more than 13 years old, it might be reasonable to remove all of the
WMM stubs from rtl8192cu and simplify related code. Minor comment
style adjustments suggested by checkpatch.pl, compile tested only.

5248f40973 binfmt: replace deprecated strncpy 
strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.

There is a _nearly_ identical implementation of fill_psinfo present in
binfmt_elf.c -- except that one uses get_task_comm over strncpy(). Let's
mirror that in binfmt_elf_fdpic.c

4962e19496 perf beauty: Move uapi/linux/vhost.h copy out of the directory used to build perf 
It is only used to generate string tables, not to build perf, so move it
to the tools/perf/trace/beauty/include/ hierarchy, that is used just for
scraping.

This is a something that should've have happened, as happened with the
linux/socket.h scrapper, do it now as Ian suggested while doing an
audit/refactor session in the headers used by perf.

No other tools/ living code uses it, just <linux/vhost.h> coming from
either 'make install_headers' or from the system /usr/include/
directory.

b3ad832d8d perf dso: Reorder members to save space in 'struct dso' 
Save 40 bytes and move from 8 to 7 cache lines. Make member dwfl
dependent on being a powerpc build. Squeeze bits of int/enum types
when appropriate. Remove holes/padding by reordering variables.

2a5049b75d perf lock contention: Trim backtrace by skipping traceiter functions 
The 'perf lock contention' program currently shows the caller of the locks
as __traceiter_contention_begin+0x??. This caller can be ignored, as it is
from the traceiter itself. Instead, it should show the real callers for
the locks.

When fiddling with the --stack-skip parameter, the actual callers for
the locks start to show up. However, just ignore the
__traceiter_contention_begin and the __traceiter_contention_end symbols
so the actual callers will show up.

Before this patch is applied:

sudo perf lock con -a -b -- sleep 3
 contended   total wait     max wait     avg wait         type   caller

         8      2.33 s       2.28 s     291.18 ms     rwlock:W   __traceiter_contention_begin+0x44

dfbc411e0a perf/x86/rapl: Prefer struct_size() over open coded arithmetic 
This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows:

  https://www.kernel.org/doc/html/latest/process/deprecated.html#open-coded-arithmetic-in-allocator-arguments
  https://github.com/KSPP/linux/issues/160

As the "rapl_pmus" variable is a pointer to "struct rapl_pmus" and
this structure ends in a flexible array:

  struct rapl_pmus {
	[...]
	struct rapl_pmu *pmus[] __counted_by(maxdie);
  };

the preferred way in the kernel is to use the struct_size() helper to
do the arithmetic instead of the calculation "size + count * size" in
the kzalloc() function.

This way, the code is more readable and safer.

3774b28d8f locking/qspinlock: Always evaluate lockevent* non-event parameter once 
The 'inc' parameter of lockevent_add() and the cond parameter of
lockevent_cond_inc() are only evaluated when CONFIG_LOCK_EVENT_COUNTS
is on. That can cause problem if those parameters are expressions
with side effect like a "++". Fix this by evaluating those non-event
parameters once even if CONFIG_LOCK_EVENT_COUNTS is off. This will also
eliminate the need of the __maybe_unused attribute to the wait_early
local variable in pv_wait_node().

a26979377b sched/doc: Update documentation for base_slice_ns and CONFIG_HZ relation 
The tunable base_slice_ns is dependent on CONFIG_HZ (i.e. TICK_NSEC)
for any significant performance improvement. The reason being the
scheduler tick is not frequent enough to force preemption when
base_slice expires in case of:

           base_slice_ns < TICK_NSEC

The below data is of stress-ng:

	Number of CPU: 1
	Stressor threads: 4
	Time: 30sec

	On CONFIG_HZ=1000

	| base_slice | avg-run (msec) | context-switches |

b4d78cfeb3 dm-integrity: align the outgoing bio in integrity_recheck 
It is possible to set up dm-integrity with smaller sector size than
the logical sector size of the underlying device. In this situation,
dm-integrity guarantees that the outgoing bios have the same alignment as
incoming bios (so, if you create a filesystem with 4k block size,
dm-integrity would send 4k-aligned bios to the underlying device).

This guarantee was broken when integrity_recheck was implemented.
integrity_recheck sends bio that is aligned to ic->sectors_per_block. So
if we set up integrity with 512-byte sector size on a device with logical
block size 4k, we would be sending unaligned bio. This triggered a bug in
one of our internal tests.

This commit fixes it by determining the actual alignment of the
incoming bio and then makes sure that the outgoing bio in
integrity_recheck has the same alignment.

Merge tag 'sh-for-v6.9-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux

Pull sh updates from John Paul Adrian Glaubitz:
 "Two patches by Ricardo B. Marliere make two instances of struct
  bus_type in the interrupt controller driver and the DMA sysfs
  interface const since the driver core in the kernel is now able to
  handle that.

  A third patch by Artur Rojek enforces internal linkage for the
  function setup_hd64461() in order to fix the build of hp6xx_defconfig
  with -Werror=missing-prototypes"

2aea94ac14 exec: Fix NOMMU linux_binprm::exec in transfer_args_to_stack() 
In NOMMU kernel the value of linux_binprm::p is the offset inside the
temporary program arguments array maintained in separate pages in the
linux_binprm::page. linux_binprm::exec being a copy of linux_binprm::p
thus must be adjusted when that array is copied to the user stack.
Without that adjustment the value passed by the NOMMU kernel to the ELF
program in the AT_EXECFN entry of the aux array doesn't make any sense
and it may break programs that try to access memory pointed to by that
entry.

Adjust linux_binprm::exec before the successful return from the
transfer_args_to_stack().
