clk: renesas: r9a09g011: Add PWM clock and reset entries

Add PWM{8..14} clock and reset entries to CPG driver.

The PWM IP on the RZ/V2M comes with 16 channels, but the ISP has
full control of channels 0 to 7, and channel 15, therefore Linux
is only allowed to use channels 8 to 14.

The PWM channel 15 shares apb clock and reset with PWM{8..14}.
The reset is deasserted by the bootloader/ISP.

Add PWM{8..14} clocks to CPG driver and mark apb clock as
critical clock, so that the apb clock will be always on.

treewide: Convert del_timer*() to timer_shutdown*()

Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown".  After a timer is set to this state, then it can no
longer be re-armed.

The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed.  It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.

This was created by using a coccinelle script and the following
commands:

    $ cat timer.cocci
    @@
    expression ptr, slab;
    identifier timer, rfield;
    @@
    (
    -       del_timer(&ptr->timer);
    +       timer_shutdown(&ptr->timer);
    |
    -       del_timer_sync(&ptr->timer);
    +       timer_shutdown_sync(&ptr->timer);
    )
      ... when strict
          when != ptr->timer
    (
            kfree_rcu(ptr, rfield);
    |
            kmem_cache_free(slab, ptr);
    |
            kfree(ptr);
    )

If mem-type is specified in the device tree
it would end up overriding the record_size

As record_size is currently parsed after the

continued to work as expected regardless of the

Simply changing the target field of the struct

cfi: Fix CFI failure with KASAN

When CFI_CLANG and KASAN are both enabled, LLVM doesn't generate a
CFI type hash for asan.module_ctor functions in translation units
where CFI is disabled, which leads to a CFI failure during boot when
do_ctors calls the affected constructors:

  CFI failure at do_basic_setup+0x64/0x90 (target:
  asan.module_ctor+0x0/0x28; expected type: 0xa540670c)

Specifically, this happens because CFI is disabled for
kernel/cfi.c. There's no reason to keep CFI disabled here anymore, so
fix the failure by not filtering out CC_FLAGS_CFI for the file.

Note that https://reviews.llvm.org/rG3b14862f0a96 fixed the issue
where LLVM didn't emit CFI type hashes for any sanitizer constructors,
but now type hashes are emitted correctly for TUs that use CFI.

perf python: Fix splitting CC into compiler and options

Noticed this build failure on archlinux:base when building with clang:

  clang-14: error: optimization flag '-ffat-lto-objects' is not supported [-Werror,-Wignored-optimization-argument]

In tools/perf/util/setup.py we check if clang supports that option, but
since commit 3cad53a6f9cdbafa ("perf python: Account for multiple words
in CC") this got broken as in the common case where CC="clang":

  >>> cc="clang"
  >>> print(cc.split()[0])
  clang
  >>> option="-ffat-lto-objects"
  >>> print(str(cc.split()[1:]) + option)
  []-ffat-lto-objects
  >>>

And then the Popen will call clang with that bogus option name that in
turn will not produce the b"unknown argument" or b"is not supported"
that this function uses to detect if the option is not available and
thus later on clang will be called with an unknown/unsupported option.

Fix it by looking if really there are options in the provided CC
variable, and if so override 'cc' with the first token and append the
options to the 'option' variable.

afs: Stop implementing ->writepage()

We're trying to get rid of the ->writepage() hook[1].  Stop afs from using
it by unlocking the page and calling afs_writepages_region() rather than
folio_write_one().

A flag is passed to afs_writepages_region() to indicate that it should only
write a single region so that we don't flush the entire file in
->write_begin(), but do add other dirty data to the region being written to
try and reduce the number of RPC ops.

This requires ->migrate_folio() to be implemented, so point that at
filemap_migrate_folio() for files and also for symlinks and directories.

This can be tested by turning on the afs_folio_dirty tracepoint and then
doing something like:

   xfs_io -c "w 2223 7000" -c "w 15000 22222" -c "w 23 7" /afs/my/test/foo

and then looking in the trace to see if the write at position 15000 gets
stored before page 0 gets dirtied for the write at position 23.

afs: Fix lost servers_outstanding count

The afs_fs_probe_dispatcher() work function is passed a count on
net->servers_outstanding when it is scheduled (which may come via its
timer).  This is passed back to the work_item, passed to the timer or
dropped at the end of the dispatcher function.

But, at the top of the dispatcher function, there are two checks which
skip the rest of the function: if the network namespace is being destroyed
or if there are no fileservers to probe.  These two return paths, however,
do not drop the count passed to the dispatcher, and so, sometimes, the
destruction of a network namespace, such as induced by rmmod of the kafs
module, may get stuck in afs_purge_servers(), waiting for
net->servers_outstanding to become zero.

Fix this by adding the missing decrements in afs_fs_probe_dispatcher().

hugetlb: really allocate vma lock for all sharable vmas

Commit bbff39cc6cbc ("hugetlb: allocate vma lock for all sharable vmas")
removed the pmd sharable checks in the vma lock helper routines.  However,
it left the functional version of helper routines behind #ifdef
CONFIG_ARCH_WANT_HUGE_PMD_SHARE.  Therefore, the vma lock is not being
used for sharable vmas on architectures that do not support pmd sharing.
On these architectures, a potential fault/truncation race is exposed that
could leave pages in a hugetlb file past i_size until the file is removed.

Move the functional vma lock helpers outside the ifdef, and remove the
non-functional stubs.  Since the vma lock is not just for pmd sharing,
rename the routine __vma_shareable_flags_pmd.

mm, mremap: fix mremap() expanding vma with addr inside vma

Since 6.1 we have noticed random rpm install failures that were tracked to
mremap() returning -ENOMEM and to commit ca3d76b0aa80 ("mm: add merging
after mremap resize").

The problem occurs when mremap() expands a VMA in place, but using an
starting address that's not vma->vm_start, but somewhere in the middle.
The extension_pgoff calculation introduced by the commit is wrong in that
case, so vma_merge() fails due to pgoffs not being compatible.  Fix the
calculation.

By the way it seems that the situations, where rpm now expands a vma from
the middle, were made possible also due to that commit, thanks to the
improved vma merging.  Yet it should work just fine, except for the buggy
calculation.

perf arm64: Simplify mksyscalltbl

This patch isn't intended to have any effect on the compiled code.  It
just removes one level of indirection: calling the *host* compiler to
build and then run a program that just printf:s the numerical entries of
the syscall-table.  In other words, the generated syscalls.c changes
from:

[46] = "ftruncate",
to:
[__NR3264_ftruncate] = "ftruncate",

The latter is as good as the former to the user of perf, and this can be
done directly by the shell-script.  The syscalls defined as non-literal
values (like "#define __NR_ftruncate __NR3264_ftruncate") are trivially
resolved at compile-time without namespace-leaking and/or collision for
its sole user, perf/util/syscalltbl.c, that just #includes the generated
file.  A future "-mabi=32" support would probably have to handle this
differently, but that is a pre-existing problem not affected by this
simplification.

Calling the *host* compiler only complicates things and accidentally can
get a completely wrong set of files and syscall numbers, see earlier
commits.  Note that the script parameter hostcc is now unused.

At the time of this patch, powerpc (the origin, see comments), and also
e.g. x86 has moved on, from filtering "gcc -dM -E" output to reading
separate specific text-file, a table of syscall numbers.  IMHO should
arm64 consider adopting this.

     incorrect state

     STATUS_OBJECT_NAME_INVALID to query info requests on DFS links in a
     namespace that contained non-ASCII characters, reducing number of
     wasted roundtrips.

   - fix for leaked -ENOMEM to userspace when cifs.ko couldn't perform
     I/O due to a disconnected server, expired or deleted session.

   - removal of all unneeded DFS related mount option string parsing
     (now using fs_context for automounts)

   - improve clarity/readability, moving various DFS related functions
     out of fs/cifs/connect.c (which was getting too big to be readable)
     to new file.

   - Fix problem when large number of DFS connections. Allow sharing of
     DFS connections and fix how the referral paths are matched

   - Referral caching fix: Instead of looking up ipc connections to
     refresh cached referrals, store direct dfs root server's IPC
     pointer in new sessions so it can simply be accessed to either
     refresh or create a new referral that such connections belong to.

   - Fix to allow dfs root server's connections to also failover

   - Optimized reconnect of nested DFS links

   - Set correct status of IPC connections marked for reconnect"

perf hist: Improve srcline sort key performance

The sort_entry->cmp() will be called for eventy sample data to find a
matching entry.  When it has 'srcline' sort key, that means it needs to
call addr2line or libbfd everytime.

This is not optimal because many samples will have same address and it
just can call addr2line once.  So postpone the actual srcline check to
the sort_entry->collpase() and compare addresses in ->cmp().

Also it needs to add ->init() callback to make sure it has srcline info.
If a sample has a unique data, chances are the entry can be sorted out
by other (previous) keys and callbacks in sort_srcline never called.

Parametrized events are not only a powerpc domain. They occur on other
platforms too (e.g. aarch64). They should be ignored in this testcase,
since proper setup of the parameters is out of scope of this script.

Let's not filter them out by PMU name, but rather based on the fact that
they expect a parameter.

Fixes: 451ed8058c69a3fe ("perf test: Fix "all PMU test" to skip hv_24x7/hv_gpci tests on powerpc")

perf tools: Add .DELETE_ON_ERROR special Makefile target to clean up partially updated files on error.

As kbuild, this adds .DELETE_ON_ERROR special target to clean up
partially updated files on error. A known issue is the empty vmlinux.h
generted by bpftool if it failed to dump btf info.
