44b0dfebbd f2fs: reflow prepare_write_begin
Reflow prepare_write_begin so that it reads more straight forward,
and so that there is one place that does an extent cache lookup
instead of three, two of which are hidden in f2fs_get_block calls.

da8c7fecc9 f2fs: rename F2FS_MAP_UNWRITTEN to F2FS_MAP_DELALLOC
NEW_ADDR blocks are purely in-memory preallocated blocks, and thus
equivalent to what the core FS code calls delayed allocations, and not
unwritten extents which do have on-disk blocks allocated from which
reads always return zeroes until they are converted to written status.

8d3c1fa3fa f2fs: don't rely on F2FS_MAP_* in f2fs_iomap_begin
When testing with a mixed zoned / convention device combination, there
are regular but not 100% reproducible failures in xfstests generic/113
where the __is_valid_data_blkaddr assert hits due to finding a hole.

This seems to be because f2fs_map_blocks can set this flag on a hole
when it was found in the extent cache.

Rework f2fs_iomap_begin to just check the special block numbers directly.
This has the added benefits of the WARN_ON showing which invalid block
address we found, and being properly error out on delalloc blocks that
are confusingly called unwritten but not actually suitable for direct
I/O.

1382999aa0 tpm: Allow system suspend to continue when TPM suspend fails
TPM 1 is sometimes broken across system suspends, due to races or
locking issues or something else that haven't been diagnosed or fixed
yet, most likely having to do with concurrent reads from the TPM's
hardware random number generator driver. These issues prevent the system
from actually suspending, with errors like:

  tpm tpm0: A TPM error (28) occurred continue selftest
  ...
  tpm tpm0: A TPM error (28) occurred attempting get random
  ...
  tpm tpm0: Error (28) sending savestate before suspend
  tpm_tis 00:08: PM: __pnp_bus_suspend(): tpm_pm_suspend+0x0/0x80 returns 28
  tpm_tis 00:08: PM: dpm_run_callback(): pnp_bus_suspend+0x0/0x10 returns 28
  tpm_tis 00:08: PM: failed to suspend: error 28
  PM: Some devices failed to suspend, or early wake event detected

This issue was partially fixed by 23393c6461 ("char: tpm: Protect
tpm_pm_suspend with locks"), in a last minute 6.1 commit that Linus took
directly because the TPM maintainers weren't available. However, it
seems like this just addresses the most common cases of the bug, rather
than addressing it entirely. So there are more things to fix still,
apparently.

In lieu of actually fixing the underlying bug, just allow system suspend
to continue, so that laptops still go to sleep fine. Later, this can be
reverted when the real bug is fixed.

cb7a95af78 hfs/hfsplus: avoid WARN_ON() for sanity check, use proper error handling
Commit 55d1cbbbb2 ("hfs/hfsplus: use WARN_ON for sanity check") fixed
a build warning by turning a comment into a WARN_ON(), but it turns out
that syzbot then complains because it can trigger said warning with a
corrupted hfs image.

The warning actually does warn about a bad situation, but we are much
better off just handling it as the error it is.  So rather than warn
about us doing bad things, stop doing the bad things and return -EIO.

While at it, also fix a memory leak that was introduced by an earlier
fix for a similar syzbot warning situation, and add a check for one case
that historically wasn't handled at all (ie neither comment nor
subsequent WARN_ON).

The following kernel panic can be triggered when a task with pid=1 attaches

31abfdda65 docs: Deprecate use of Sphinx < 2.4.x
The Sphinx 2.4 release is three years old, and it is becoming increasingly
difficult to even find a system with an sufficiently archaic Python
installation that can run versions older than that.  I can no longer test
changes against anything prior to 2.4.x.

Move toward raising our minimum Sphinx requirement to 2.4.x so we can
delete some older support code and claim to support a range of versions
that we can actually test.

In the absence of screams, the actual removal of support can happen later
in 2023.

Sphinx 6.0 removed the execfile_() function, which we use as part of the
configuration process.  They *did* warn us...  Just open-code the
functionality as is done in Sphinx itself.

Tested (using SPHINX_CONF, since this code is only executed with an
alternative config file) on various Sphinx versions from 2.5 through 6.0.

56f8145839 perf tools fixes for v6.2: 1st batch
- Fix segfault when trying to process tracepoints present in a perf.data file
   and not linked with libtraceevent.
 
 - Fix build on uClibc systems by adding missing sys/types.h include, that was
   being obtained indirectly which stopped being the case when tools/lib/traceevent
   was removed.
 
 - Don't show commands in 'perf help' that depend on linking with libtraceevent
   when not building with that library, which is now a possibility since we
   no longer ship a copy in tools/lib/traceevent.
 
 - Fix failure in 'perf test' entry testing the combination of 'perf probe' user
   space function + 'perf record' + 'perf script' where it expects a backtrace
   leading to glibc's inet_pton() from 'ping' that now happens more than once with
   glibc 2.35 for IPv6 addreses.
 
 - Fix for the inet_pton perf test on s/390 where 'text_to_binary_address' now
   appears on the backtrace.
 
 - Fix build error on riscv due to missing header for 'struct perf_sample'.
 
 - Fix 'make -C tools perf_install' install variant by not propagating the 'subdir'
   to submakes for the 'install_headers' targets.
 
 - Fix handling of unsupported cgroup events when using BPF counters in 'perf stat'.
 
 - Count all cgroups, not just the last one when using 'perf stat
   --for-each-cgroup' with --bpf-counters. This makes the output using BPF
   counters match the output without using it, which was the intention all along,
   the output should be the same using --bpf-counters or not.
 
 - Fix 'perf lock contention' core dump related to not finding the

 - Fix build failure when HEAD is signed: exclude the signature from the version
   string.
 
 - Add missing closedir() calls to in perf_data__open_dir(), plugging a fd leak.

From: Conor Dooley <conor.dooley@microchip.com>

I noticed ~today~ while looking at the isa manual that I had not
accounted for another couple of edge cases with my regex. As before, I
think attempting to validate the canonical order for multiletter stuff
makes no sense - but we should totally try to avoid false-positives for
combinations that are known to be valid.

dt-bindings: riscv: fix single letter canonical order
I used the wikipedia table for ordering extensions when updating the
pattern here in commit 299824e68b ("dt-bindings: riscv: add new
riscv,isa strings for emulators").

Unfortunately that table did not match canonical order, as defined by
the RISC-V ISA Manual, which defines extension ordering in (what is
currently) Table 41, "Standard ISA extension names". Fix things up by
re-sorting v (vector) and adding p (packed-simd) & j (dynamic
languages). The e (reduced integer) and g (general) extensions are still
intentionally left out.

dt-bindings: riscv: fix underscore requirement for multi-letter extensions
The RISC-V ISA Manual allows the first multi-letter extension to avoid
a leading underscore. Underscores are only required between multi-letter
extensions.

The dt-binding does not validate that a multi-letter extension is
canonically ordered, as that'd need an even worse regex than is here,
but it should not fail validation for valid ISA strings.

Allow the first multi-letter extension to appear immediately after
the single-letter extensions.

0b3a551fa5 nfsd: fix handling of cached open files in nfsd4_open codepath
Commit fb70bf124b ("NFSD: Instantiate a struct file when creating a
regular NFSv4 file") added the ability to cache an open fd over a
compound. There are a couple of problems with the way this currently
works:

It's racy, as a newly-created nfsd_file can end up with its PENDING bit
cleared while the nf is hashed, and the nf_file pointer is still zeroed
out. Other tasks can find it in this state and they expect to see a
valid nf_file, and can oops if nf_file is NULL.

Also, there is no guarantee that we'll end up creating a new nfsd_file
if one is already in the hash. If an extant entry is in the hash with a
valid nf_file, nfs4_get_vfs_file will clobber its nf_file pointer with
the value of op_file and the old nf_file will leak.

Fix both issues by making a new nfsd_file_acquirei_opened variant that
takes an optional file pointer. If one is present when this is called,
we'll take a new reference to it instead of trying to open the file. If
the nfsd_file already has a valid nf_file, we'll just ignore the
optional file and pass the nfsd_file back as-is.

Also rework the tracepoints a bit to allow for an "opened" variant and
don't try to avoid counting acquisitions in the case where we already
have a cached open file.

shared schema") made the "qcom,protection-domain" required but it
should remain optional to avoid dtbs_check warnings on older platforms,
e.g.:

arch/arm64/boot/dts/qcom/apq8096-db820c.dtb:
  apr: service@3: 'qcom,protection-domain' is a required property
  From schema: Documentation/devicetree/bindings/soc/qcom/qcom,apr.yaml

33ae3d0955 soc: qcom: apr: make remove callback of apr driver void returned
Since commit fc7a6209d5 ("bus: Make remove callback return void")
forces bus_type::remove be void-returned, it doesn't make much sense
for any bus based driver implementing remove callbalk to return
non-void to its caller.

As such, change the remove function for apr bus based drivers to
return void.

spi: spidev: remove debug messages that access spidev->spi without locking
The two debug messages in spidev_open() dereference spidev->spi without
taking the lock and without checking if it's not null. This can lead to
a crash. Drop the messages as they're not needed - the user-space will
get informed about ENOMEM with the syscall return value.

spi: spidev: fix a race condition when accessing spidev->spi
There's a spinlock in place that is taken in file_operations callbacks
whenever we check if spidev->spi is still alive (not null). It's also
taken when spidev->spi is set to NULL in remove().

This however doesn't protect the code against driver unbind event while
one of the syscalls is still in progress. To that end we need a lock taken
continuously as long as we may still access spidev->spi. As both the file
ops and the remove callback are never called from interrupt context, we
can replace the spinlock with a mutex.

5db568e748 arm64: errata: Workaround possible Cortex-A715 [ESR|FAR]_ELx corruption
If a Cortex-A715 cpu sees a page mapping permissions change from executable
to non-executable, it may corrupt the ESR_ELx and FAR_ELx registers, on the
next instruction abort caused by permission fault.

Only user-space does executable to non-executable permission transition via
mprotect() system call which calls ptep_modify_prot_start() and ptep_modify
_prot_commit() helpers, while changing the page mapping. The platform code
can override these helpers via __HAVE_ARCH_PTEP_MODIFY_PROT_TRANSACTION.

Work around the problem via doing a break-before-make TLB invalidation, for
all executable user space mappings, that go through mprotect() system call.
This overrides ptep_modify_prot_start() and ptep_modify_prot_commit(), via
defining HAVE_ARCH_PTEP_MODIFY_PROT_TRANSACTION on the platform thus giving
an opportunity to intercept user space exec mappings, and do the necessary
TLB invalidation. Similar interceptions are also implemented for HugeTLB.

cef139299f firmware/psci: Don't register with debugfs if PSCI isn't available
Contrary to popular belief, PSCI is not a universal property of an
ARM/arm64 system. There is a garden variety of systems out there
that don't (or even cannot) implement it.

I'm the first one deplore such a situation, but hey...

On such systems, a "cat /sys/kernel/debug/psci" results in
fireworks, as no invocation callback is registered.

Check for the invoke_psci_fn and psci_ops.get_version pointers
before registering with the debugfs subsystem, avoiding the
issue altogether.
