17eabd4256 afs: Fix infinite loop found by xfstest generic/676
In AFS, a directory is handled as a file that the client downloads and
parses locally for the purposes of performing lookup and getdents
operations.  The in-kernel afs filesystem has a number of functions that
do this.

A directory file is arranged as a series of 2K blocks divided into
32-byte slots, where a directory entry occupies one or more slots, plus
each block starts with one or more metadata blocks.

When parsing a block, if the last slots are occupied by a dirent that
occupies more than a single slot and the file position points at a slot
that's not the initial one, the logic in afs_dir_iterate_block() that
skips over it won't advance the file pointer to the end of it.  This
will cause an infinite loop in getdents() as it will keep retrying that
block and failing to advance beyond the final entry.

Fix this by advancing the file pointer if the next entry will be beyond
it when we skip a block.

This was found by the generic/676 xfstest but can also be triggered with
something like:

	~/xfstests-dev/src/t_readdir_3 /xfstest.test/z 4000 1

8eca6b0a64 pwm: Changes for v5.19-rc1
Quite a large number of conversions this time around, courtesy of Uwe
 who has been working tirelessly on these. No drivers of the legacy API
 are left at this point, so as a next step the old API can be removed.
 
 Support is added for a few new devices such as the Xilinx AXI timer-
 based PWMs and the PWM IP found on Sunplus SoCs.
 
 Other than that, there's a number of fixes, cleanups and optimizations.

Pull pwm updates from Thierry Reding:
 "Quite a large number of conversions this time around, courtesy of Uwe
  who has been working tirelessly on these. No drivers of the legacy API
  are left at this point, so as a next step the old API can be removed.

  Support is added for a few new devices such as the Xilinx AXI timer-
  based PWMs and the PWM IP found on Sunplus SoCs.

  Other than that, there's a number of fixes, cleanups and optimizations"

f634b63d43 remoteproc updates for v5.19
This fixes a race condition in the user space interface for starting and
 stopping remote processors, it makes the ELF loader properly skip zero
 memsz segments and it cleans up the debugfs tracefile code a bit by not
 checking for errors.
 
 It introduces support for controlling the audio DSP on Qualcomm MSM8226,
 as well as audio and compute DSPs on Qualcomm SC8280XP.
 
 It makes it possible to specify the firmware path for Mediatek's remote
 processors, fixes a double free in the SCP driver and addresses an issue
 with the SRAM initialization on MT8195.
 
 Lastly it deprecates the custom ELF loader in the iMX remoteproc driver,
 in favor of using the shared one.

1501f707d2 f2fs-for-5.19
In this round, we've refactored the existing atomic write support implemented
 by in-memory operations to have storing data in disk temporarily, which can give
 us a benefit to accept more atomic writes. At the same time, we removed the
 existing volatile write support. We've also revisited the file pinning and GC
 flows and found some corner cases which contributeed abnormal system behaviours.
 As usual, there're several minor code refactoring for readability, sanity check,
 and clean ups.
 
 Enhancement
  - allow compression for mmap files in compress_mode=user
  - kill volatile write support
  - change the current atomic write way
  - give priority to select unpinned section for foreground GC
  - introduce data read/write showing path info
  - remove unnecessary f2fs_lock_op in f2fs_new_inode
 
 Bug fix
  - fix the file pinning flow during checkpoint=disable and GCs
  - fix foreground and background GCs to select the right victims and get free
    sections on time
  - fix GC flags on defragmenting pages
  - avoid an infinite loop to flush node pages

4caae58406 dm verity: set DM_TARGET_IMMUTABLE feature flag
The device-mapper framework provides a mechanism to mark targets as
immutable (and hence fail table reloads that try to change the target
type). Add the DM_TARGET_IMMUTABLE flag to the dm-verity target's
feature flags to prevent switching the verity target with a different
target type.

9571f829f3 dm table: fix dm_table_supports_poll to return false if no data devices
It was reported that the "generic/250" test in xfstests (which uses
the dm-error target) demonstrates a regression where the kernel
crashes in bioset_exit().

Since commit cfc97abcbe ("dm: conditionally enable
BIOSET_PERCPU_CACHE for dm_io bioset") the bioset_init() for the dm_io
bioset will setup the bioset's per-cpu alloc cache if all devices have
QUEUE_FLAG_POLL set.

But there was an bug where a target that doesn't have any data devices
(and that doesn't even set the .iterate_devices dm target callback)
will incorrectly return true from dm_table_supports_poll().

Fix this by updating dm_table_supports_poll() to follow dm-table.c's
well-worn pattern for testing that _all_ targets in a DM table do in
fact have underlying devices that set QUEUE_FLAG_POLL.

NOTE: An additional block fix is still needed so that
bio_alloc_cache_destroy() clears the bioset's ->cache member.
Otherwise, a DM device's table reload that transitions the DM device's
bioset from using a per-cpu alloc cache to _not_ using one will result
in bioset_exit() crashing in bio_alloc_cache_destroy() because dm's
dm_io bioset ("io_bs") was left with a stale ->cache member.

Merge general ACPI cleanups and processor support updates for 5.19-rc1:

 - Rearrange find_child_checks() to simplify code (Rafael Wysocki).

 - Use memremap() to map the UCSI mailbox that is always in main memory
   and drop acpi_release_memory() that has no more users (Heikki
   Krogerus, Dan Carpenter).

 - Make max_cstate/nocst/bm_check_disable processor module parameters
   visible in sysfs (Yajun Deng).

 - Fix typo in the CPPC driver (Julia Lawall).

The devm_memremap() function never returns NULL.  It returns error
pointers.

Building the cppc_cpufreq driver with for arm64 with
CONFIG_ENERGY_MODEL=n triggers the following warnings:
 drivers/cpufreq/cppc_cpufreq.c:550:12: error: ‘cppc_get_cpu_cost’ defined but not used
[-Werror=unused-function]
   550 | static int cppc_get_cpu_cost(struct device *cpu_dev, unsigned long KHz,

   481 | static int cppc_get_cpu_power(struct device *cpu_dev,
       |            ^~~~~~~~~~~~~~~~~~

Move the Energy Model related functions into specific guards.
This allows to fix the warning and prevent doing extra work
when the Energy Model is not present.
