The core function maintains the instance of fw_device structure by IDR.
The concurrent access to IDR is protected by static read/write semaphore.
The semaphore is also utilized to protect concurrent access to the
content of configuration ROM cached to the instance so that the cache is
swapped to the latest one.

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

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.

This name is aligned with other Arm boards (those didn't have a known

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.

KVM/riscv fixes for 6.11, take #1

- Fix compile error in get-reg-list selftests

Pull s390 fixes from Vasily Gorbik:

 - remove unused empty CPU alternatives header file

 - fix recently and erroneously removed exception handling when loading
   an invalid floating point register

 - ptdump fixes to reflect the recent changes due to the uncoupling of
   physical vs virtual kernel address spaces

 - changes to avoid the unnecessary splitting of large pages in kernel
   mappings

 - add the missing MODULE_DESCRIPTION for the CIO modules
