The kernel sleep profile is no longer working due to a recursive locking
bug introduced by commit 42a20f86 ("sched: Add wrapper for get_wchan()
to keep task blocked")

Booting with the 'profile=sleep' kernel command line option added or
executing

  # echo -n sleep > /sys/kernel/profiling

after boot causes the system to lock up.

Lockdep reports

  kthreadd/3 is trying to acquire lock:
  ffff93ac82e08d58 (&p->pi_lock){....}-{2:2}, at: get_wchan+0x32/0x70

  but task is already holding lock:
  ffff93ac82e08d58 (&p->pi_lock){....}-{2:2}, at: try_to_wake_up+0x53/0x370

with the call trace being

   lock_acquire+0xc8/0x2f0
   get_wchan+0x32/0x70
   __update_stats_enqueue_sleeper+0x151/0x430
   enqueue_entity+0x4b0/0x520

   swake_up_locked+0x20/0x50
   complete+0x2f/0x40
   kthread+0xfb/0x180

However, since nobody noticed this regression for more than two years,
let's remove 'profile=sleep' support based on the assumption that nobody
needs this functionality.

Pull x86 fixes from Thomas Gleixner:

 - Prevent a deadlock on cpu_hotplug_lock in the aperf/mperf driver.

   A recent change in the ACPI code which consolidated code pathes moved
   the invocation of init_freq_invariance_cppc() to be moved to a CPU
   hotplug handler. The first invocation on AMD CPUs ends up enabling a
   static branch which dead locks because the static branch enable tries
   to acquire cpu_hotplug_lock but that lock is already held write by
   the hotplug machinery.

   Use static_branch_enable_cpuslocked() instead and take the hotplug
   lock read for the Intel code path which is invoked from the
   architecture code outside of the CPU hotplug operations.

 - Fix the number of reserved bits in the sev_config structure bit field
   so that the bitfield does not exceed 64 bit.

 - Add missing Zen5 model numbers

 - Fix the alignment assumptions of pti_clone_pgtable() and
   clone_entry_text() on 32-bit:

   The code assumes PMD aligned code sections, but on 32-bit the kernel
   entry text is not PMD aligned. So depending on the code size and
   location, which is configuration and compiler dependent, entry text
   can cross a PMD boundary. As the start is not PMD aligned adding PMD
   size to the start address is larger than the end address which
   results in partially mapped entry code for user space. That causes
   endless recursion on the first entry from userspace (usually #PF).

   Cure this by aligning the start address in the addition so it ends up
   at the next PMD start address.

   clone_entry_text() enforces PMD mapping, but on 32-bit the tail might
   eventually be PTE mapped, which causes a map fail because the PMD for
   the tail is not a large page mapping. Use PTI_LEVEL_KERNEL_IMAGE for
   the clone() invocation which resolves to PTE on 32-bit and PMD on
   64-bit.

 - Zero the 8-byte case for get_user() on range check failure on 32-bit

   The recend consolidation of the 8-byte get_user() case broke the
   zeroing in the failure case again. Establish it by clearing ECX
   before the range check and not afterwards as that obvioulsy can't be
   reached when the range check fails

Pull timer fixes from Thomas Gleixner:
 "Two fixes for the timer/clocksource code:

   - The recent fix to make the take over of the broadcast timer more
     reliable retrieves a per CPU pointer in preemptible context.

     This went unnoticed in testing as some compilers hoist the access
     into the non-preemotible section where the pointer is actually
     used, but obviously compilers can rightfully invoke it where the
     code put it.

     Move it into the non-preemptible section right to the actual usage
     side to cure it.

   - The clocksource watchdog is supposed to emit a warning when the
     retry count is greater than one and the number of retries reaches
     the limit.

     The condition is backwards and warns always when the count is
     greater than one. Fixup the condition to prevent spamming dmesg"

Pull scheduler fixes from Thomas Gleixner:

 - When stime is larger than rtime due to accounting imprecision, then
   utime = rtime - stime becomes negative. As this is unsigned math, the
   result becomes a huge positive number.

   Cure it by resetting stime to rtime in that case, so utime becomes 0.

 - Restore consistent state when sched_cpu_deactivate() fails.

   When offlining a CPU fails in sched_cpu_deactivate() after the SMT
   present counter has been decremented, then the function aborts but
   fails to increment the SMT present counter and leaves it imbalanced.
   Consecutive operations cause it to underflow. Add the missing fixup
   for the error path.

   For SMT accounting the runqueue needs to marked online again in the
   error exit path to restore consistent state.

Commit 04f08ef2 ("arm/arm64: dts: arm: Use generic clock and

(at different paths).

The kernel can't handle these duplicate names even though they are at
different paths.  Fix this by renaming one of the nodes to "clock-pclk".

This name is aligned with other Arm boards (those didn't have a known
frequency to use in the node name).

The runtime constants linker script depended on documented linker
behavior [1]:

 "If an output section’s name is the same as the input section’s name
  and is representable as a C identifier, then the linker will
  automatically PROVIDE two symbols: __start_SECNAME and __stop_SECNAME,
  where SECNAME is the name of the section. These indicate the start
  address and end address of the output section respectively"

to just automatically define the symbol names for the bounds of the
runtime constant arrays.

It turns out that this isn't actually something we can rely on, with old
linkers not generating these automatic symbols.  It looks to have been
introduced in binutils-2.29 back in 2017, and we still support building
with versions all the way back to binutils-2.25 (from 2015).

And yes, Oleg actually seems to be using such ancient versions of
binutils.

So instead of depending on the implicit symbols from "section names
match and are representable C identifiers", just do this all manually.
It's not like it causes us any extra pain, we already have to do that
for all the other sections that we use that often have special
characters in them.

NetApp server requires the file to be open with FILE_READ_EA access in
order to support FSCTL_GET_REPARSE_POINT, otherwise it will return
STATUS_INVALID_DEVICE_REQUEST.  It doesn't make any sense because
there's no requirement for FILE_READ_EA bit to be set nor
STATUS_INVALID_DEVICE_REQUEST being used for something other than
"unsupported reparse points" in MS-FSA.

To fix it and improve compatibility, set FILE_READ_EA & SYNCHRONIZE
bits to match what Windows client currently does.

For debugging an umount failure in xfstests generic/043 generic/044 in some
configurations, we needed more information on the shutdown ioctl which
was suspected of being related to the cause, so tracepoints are added
in this patch e.g.

  "trace-cmd record -e smb3_shutdown_enter -e smb3_shutdown_done -e smb3_shutdown_err"

Sample output:
  godown-47084   [011] .....  3313.756965: smb3_shutdown_enter: flags=0x1 tid=0x733b3e75
  godown-47084   [011] .....  3313.756968: smb3_shutdown_done: flags=0x1 tid=0x733b3e75

As per MS-FSA 2.1.5.10.14, support for FSCTL_GET_REPARSE_POINT is
optional and if the server doesn't support it,
STATUS_INVALID_DEVICE_REQUEST must be returned for the operation.

If we find files with reparse points and we can't read them due to
lack of client or server support, just ignore it and then treat them
as regular files or junctions.

Although the Arm architecture permits concurrent modification and
execution of NOP and branch instructions, it still requires some
synchronisation to ensure that other CPUs consistently execute the newly
written instruction:

 >  When the modified instructions are observable, each PE that is
 >  executing the modified instructions must execute an ISB or perform a
 >  context synchronizing event to ensure execution of the modified
 >  instructions

Prior to commit f6cc0c50 ("arm64: Avoid calling stop_machine() when
patching jump labels"), the arm64 jump_label patching machinery
performed synchronisation using stop_machine() after each modification,
however this was problematic when flipping static keys from atomic
contexts (namely, the arm_arch_timer CPU hotplug startup notifier) and
so we switched to the _nosync() patching routines to avoid "scheduling
while atomic" BUG()s during boot.

In hindsight, the analysis of the issue in f6cc0c50 isn't quite
right: it cites the use of IPIs in the default patching routines as the
cause of the lockup, whereas stop_machine() does not rely on IPIs and
the I-cache invalidation is performed using __flush_icache_range(),
which elides the call to kick_all_cpus_sync(). In fact, the blocking
wait for other CPUs is what triggers the BUG() and the problem remains
even after f6cc0c50, for example because we could block on the
jump_label_mutex. Eventually, the arm_arch_timer driver was fixed to
avoid the static key entirely in commit a862fc22
("clocksource/arm_arch_timer: Remove use of workaround static key").

This all leaves the jump_label patching code in a funny situation on
arm64 as we do not synchronise with other CPUs to reduce the likelihood
of a bug which no longer exists. Consequently, toggling a static key on
one CPU cannot be assumed to take effect on other CPUs, leading to
potential issues, for example with missing preempt notifiers.

Rather than revert f6cc0c50 and go back to stop_machine() for each
patch site, implement arch_jump_label_transform_apply() and kick all
the other CPUs with an IPI at the end of patching.

The __NR_newfstat and __NR_newfstatat macros accidentally got renamed
in the conversion to the syscall.tbl format, dropping the 'new' portion
of the name.

In an unrelated change, the two syscalls are no longer architecture
specific but are once more defined on all 64-bit architectures, so the
'newstat' ABI keyword can be dropped from the table as a simplification.

Despite multiple attempts to get the syscall number assignment right
for the newly added uretprobe syscall, we ended up with a bit of a mess:

 - The number is defined as 467 based on the assumption that the
   xattrat family of syscalls would use 463 through 466, but those
   did not make it into 6.11.

 - The include/uapi/asm-generic/unistd.h file still lists the number
   463, but the new scripts/syscall.tbl that was supposed to have the
   same data lists 467 instead as the number for arc, arm64, csky,
   hexagon, loongarch, nios2, openrisc and riscv. None of these
   architectures actually provide a uretprobe syscall.

 - All the other architectures (powerpc, arm, mips, ...) don't list
   this syscall at all.

There are two ways to make it consistent again: either list it with
the same syscall number on all architectures, or only list it on x86
but not in scripts/syscall.tbl and asm-generic/unistd.h.

Based on the most recent discussion, it seems like we won't need it
anywhere else, so just remove the inconsistent assignment and instead
move the x86 number to the next available one in the architecture
specific range, which is 335.

The thermal sysfs API document is outdated.  One of the problems with
it is that is still documents thermal_zone_device_register() which
does not exit any more and it does not reflect the current thermal
zone operations definition.

Replace the thermal_zone_device_register() description in it with
a thermal_zone_device_register_with_trips() description, including
an update of the thermal zone operations list.
