PPC_RAW_TW() is erroneously defined with base code 0x7f000008
instead of 0x7c000008.

That's invisible because its only user is PPC_RAW_TRAP() which is
0x7fe00008, but fix it anyway to avoid any risk of future bug.

Just like the first patch of this series, define a local 'eh' in order
to make the code clearer.

And IS_ENABLED() returns either 1 or 0 so no need to do
IS_ENABLED(CONFIG_PPC64) ? 1 : 0.

The eh field must remain 0 for PPC32 and is only used
by PPC64.

Don't hide that behind a macro, just leave the responsibility
to the user.

At the time being, the only users of PPC_RAW_L{WDQ}ARX are
setting the eh field to 0, so the special handling of __PPC_EH
is useless. Just take the value given by the caller.

Same for DEFINE_TESTOP(), don't do special handling in that
macro, ensure the caller hands over the proper eh value.

Commit 9401f4e4 ("powerpc: Use lwarx/ldarx directly instead of
PPC_LWARX/LDARX macros") properly handled the eh field of lwarx
in asm/bitops.h but failed to clear it for PPC32 in
asm/simple_spinlock.h

So, do as in arch_atomic_try_cmpxchg_lock(), set it to 1 if PPC64
but set it to 0 if PPC32. For that use IS_ENABLED(CONFIG_PPC64) which
returns 1 when CONFIG_PPC64 is set and 0 otherwise.

This reverts commit 4bf7fda4.

It turns out that it was hopelessly naive to think that this would work,
considering that we've always done this.  The first machine I actually
tested this on broke at bootup, getting to

    Reached target cryptsetup.target - Local Encrypted Volumes.

and then hanging.  It's unclear what actually fails, since there's a lot
else going on around that time (eg amdgpu probing also happens around
that same time, but it could be some other random init thing that didn't
complete earlier and just caused the boot to hang at that point).

The expectations that we should default to some unsafe and untested mode
seems entirely unfounded, and the belief that this wouldn't affect
modern systems is clearly entirely false.  The machine in question is
about two years old, so it's not exactly shiny, but it's also not some
dusty old museum piece PDP-11 in a closet.

Pull more device mapper updates from Mike Snitzer:

 - Add flags argument to dm_bufio_client_create and introduce
   DM_BUFIO_CLIENT_NO_SLEEP flag to have dm-bufio use spinlock rather
   than mutex for its locking.

 - Add optional "try_verify_in_tasklet" feature to DM verity target.
   This feature gives users the option to improve IO latency by using a
   tasklet to verify, using hashes in bufio's cache, rather than wait to
   schedule a work item via workqueue. But if there is a bufio cache
   miss, or an error, then the tasklet will fallback to using workqueue.

 - Incremental changes to both dm-bufio and the DM verity target to use
   jump_label to minimize cost of branching associated with the niche
   "try_verify_in_tasklet" feature. DM-bufio in particular is used by
   quite a few other DM targets so it doesn't make sense to incur
   additional bufio cost in those targets purely for the benefit of this
   niche verity feature if the feature isn't ever used.

 - Optimize verity_verify_io, which is used by both workqueue and
   tasklet based verification, if FEC is not configured or tasklet based
   verification isn't used.

 - Remove DM verity target's verify_wq's use of the WQ_CPU_INTENSIVE
   flag since it uses WQ_UNBOUND. Also, use the WQ_HIGHPRI flag if
   "try_verify_in_tasklet" is specified.

Pull iommu updates from Joerg Roedel:

 - The most intrusive patch is small and changes the default allocation
   policy for DMA addresses.

   Before the change the allocator tried its best to find an address in
   the first 4GB. But that lead to performance problems when that space
   gets exhaused, and since most devices are capable of 64-bit DMA these
   days, we changed it to search in the full DMA-mask range from the
   beginning.

   This change has the potential to uncover bugs elsewhere, in the
   kernel or the hardware. There is a Kconfig option and a command line
   option to restore the old behavior, but none of them is enabled by
   default.

Pull sound updates from Takashi Iwai:
 "As the diffstat shows, we've had lots of developments in a wide range
  at this time; the majority of changes are about ASoC, including
  subsystem-wide cleanups, continued SOF / Intel updates and a bunch of
  new drivers (as usual), while there have been some significant (but
  almost invisible) improvements in ALSA core side, too.

  Below are some highlights:

  Core:

   - Faster lookups of control elements with Xarray; normal user won't
     notice, but on the devices with tons of control elements, it can be
     visibly faster

   - Support for input validation for controls; this will harden for
     badly written drivers in general with a slight overhead

   - Deferred async signal handling for working around the potential
     deadlocks

   - Cleanup / refactoring raw MIDI locking code

  ASoC:

   - Restructing of the set_fmt() callbacks for making things clearer in
     situations like CODEC to CODEC links

   - Clean up and modernizing the DAI naming scheme setups

   - Merge of more of the Intel AVS driver stack, including some board
     integrations

   - New version 4 mechanism for communication with SOF DSPs

   - Suppoort for dynamically selecting the PLL to use at runtime on
     i.MX platforms

   - Improvements for CODEC to CODEC support in the generic cards

Pull perf tools updates from Arnaldo Carvalho de Melo:

 - Introduce 'perf lock contention' subtool, using new lock contention
   tracepoints and using BPF for in kernel aggregation and then
   userspace processing using the perf tooling infrastructure for
   resolving symbols, target specification, etc.

   Since the new lock contention tracepoints don't provide lock names,
   get up to 8 stack traces and display the first non-lock function
   symbol name as a caller:

    $ perf lock report -F acquired,contended,avg_wait,wait_total

 - Add support for new AMD IBS (Instruction Based Sampling) features:

   With the DataSrc extensions, the source of data can be decoded among:
     - Local L3 or other L1/L2 in CCX.
     - A peer cache in a near CCX.
     - Data returned from DRAM.
     - A peer cache in a far CCX.
     - DRAM address map with "long latency" bit set.
     - Data returned from MMIO/Config/PCI/APIC.

   the traces with the ones in the host machine.

 - Add a "-m" option to 'perf buildid-list' to show kernel and modules
   build-ids, to display all of the information needed to do external
   symbolization of kernel stack traces, such as those collected by
   bpf_get_stackid().

 - Add arch TSC frequency information to perf.data file headers.

 - Handle changes in the binutils disassembler function signatures in
   perf, bpftool and bpf_jit_disasm (Acked by the bpftool maintainer).

 "Most of the MM queue. A few things are still pending.

  Liam's maple tree rework didn't make it. This has resulted in a few

  Multi-gen LRU still isn't merged as we were waiting for mapletree to
  stabilize. The current plan is to merge MGLRU into -mm soon and to
  later reintroduce mapletree, with a view to hopefully getting both
  into 6.1-rc1.

  SPI NOR core changes:

   - move SECT_4K_PMC flag out of the core as it's a vendor specific
     flag

   - s/addr_width/addr_nbytes/g: address width means the number of IO
     lines used for the address, whereas in the code it is used as the
     number of address bytes.

   - do not change nor->addr_nbytes at SFDP parsing time. At the SFDP
     parsing time we should not change members of struct spi_nor, but
     instead fill members of struct spi_nor_flash_parameters which could
     later on be used by the callers.

   - track flash's internal address mode so that we can use 4B opcodes
     together with opcodes that don't have a 4B opcode correspondent.

   - esmt: Rename "f25l32qa" flash name to "f25l32qa-2s".

     of the MMIO accessors, which is intended to help understand
     problems with device drivers and has been part of Qualcomm's vendor
     kernels for many years

   - A patch from Sebastian Siewior to rework the handling of IRQ stacks
     in softirqs across architectures, which is needed for enabling
     PREEMPT_RT

   - The last patch to remove the CONFIG_VIRT_TO_BUS option and some of

   - The reset controller tree adds one new driver for the TI TPS380x
     power management chip and a few minor changes in other drivers

   - Apple M1 now has a DT entry for the NVMe controller after the
     driver was merged, and has a new mailing list in the MAINTAINERS

Pull tracing updates from Steven Rostedt:

 - Runtime verification infrastructure

   This is the biggest change here. It introduces the runtime
   verification that is necessary for running Linux on safety critical
   systems.

   It allows for deterministic automata models to be inserted into the
   kernel that will attach to tracepoints, where the information on
   these tracepoints will move the model from state to state.

   If a state is encountered that does not belong to the model, it will
   then activate a given reactor, that could just inform the user or
   even panic the kernel (for which safety critical systems will detect
   and can recover from).

 - Two monitor models are also added: Wakeup In Preemptive (WIP - not to
   be confused with "work in progress"), and Wakeup While Not Running
   (WWNR).

 - Added __vstring() helper to the TRACE_EVENT() macro to replace
   several vsnprintf() usages that were all doing it wrong.

 - eprobes now can have their event autogenerated when the event name is
   left off.

 - The rest is various cleanups and fixes.

Pull xfs updates from Darrick Wong:
 "The biggest changes for this release are the log scalability
  improvements, lockless lookups for the buffer cache, and making the
  attr fork a permanent part of the incore inode in preparation for
  directory parent pointers.

  There's also a bunch of bug fixes that have accumulated since -rc5. I
  might send you a second pull request with some more bug fixes that I'm
  still working on.

  Once the merge window ends, I will hand maintainership back to Dave
  Chinner until the 6.1-rc1 release so that I can conduct the design
  review for the online fsck feature, and try to get it merged.

  Summary:

   - Improve scalability of the XFS log by removing spinlocks and global
     synchronization points.

   - Add security labels to whiteout inodes to match the other
     filesystems.

   - Clean up per-ag pointer passing to simplify call sites.

   - Reduce verifier overhead by precalculating more AG geometry.

   - Implement fast-path lockless lookups in the buffer cache to reduce
     spinlock hammering.

   - Make attr forks a permanent part of the inode structure to fix a
     UAF bug and because most files these days tend to have security
     labels and soon will have parent pointers too.

   - Clean up XFS_IFORK_Q usage and give it a better name.

   - Fix more UAF bugs in the xattr code.

   - SOB my tags.

   - Fix some typos in the timestamp range documentation.

   - Fix a few more memory leaks.

   - Code cleanups and typo fixes.

   - Fix an unlocked inode fork pointer access in getbmap"
