In function device_init_td0_ring, memory is allocated for member
td_info of priv->apTD0Rings[i], with i increasing from 0. In case of
allocation failure, the memory is freed in reversed order, with i
decreasing to 0. However, the case i=0 is left out and thus memory is

very real potential for this code to remove ALL debugfs entries from the
system, and it seems like this is what will really happen if this code
ever runs.  This all is very wrong as the greybus audio driver did not
create this debugfs file, the sound core did and controls the lifespan
of it.

So remove all of the debugfs logic from the audio_helper code as there's
no way it could be correct.  If this really is needed, it can come back

Makefile.extrawarn: re-enable -Wformat for clang; take 2

-Wformat was recently re-enabled for builds with clang, then quickly
re-disabled, due to concerns stemming from the frequency of default
argument promotion related warning instances.

commit 258fafcd0683 ("Makefile.extrawarn: re-enable -Wformat for clang")
commit 21f9c8a13bb2 ("Revert "Makefile.extrawarn: re-enable -Wformat for clang"")

ISO WG14 has ratified N2562 to address default argument promotion
explicitly for printf, as part of the upcoming ISO C2X standard.

The behavior of clang was changed in clang-16 to not warn for the cited
cases in all language modes.

Add a version check, so that users of clang-16 now get the full effect
of -Wformat. For older clang versions, re-enable flags under the
-Wformat group that way users still get some useful checks related to
format strings, without noisy default argument promotion warnings. I
intentionally omitted -Wformat-y2k and -Wformat-security from being
re-enabled, which are also part of -Wformat in clang-16.

22 months agomm: pagewalk: Fix race between unmap and page walker
Steven Price [Fri, 2 Sep 2022 11:26:12 +0000 (12:26 +0100)]
mm: pagewalk: Fix race between unmap and page walker

The mmap lock protects the page walker from changes to the page tables
during the walk.  However a read lock is insufficient to protect those
areas which don't have a VMA as munmap() detaches the VMAs before
downgrading to a read lock and actually tearing down PTEs/page tables.

For users of walk_page_range() the solution is to simply call pte_hole()
immediately without checking the actual page tables when a VMA is not
present. We now never call __walk_page_range() without a valid vma.

For walk_page_range_novma() the locking requirements are tightened to
require the mmap write lock to be taken, and then walking the pgd
directly with 'no_vma' set.

This in turn means that all page walkers either have a valid vma, or
it's that special 'novma' case for page table debugging.  As a result,
all the odd '(!walk->vma && !walk->no_vma)' tests can be removed.

LoongArch: Fix section mismatch due to acpi_os_ioremap()

Now acpi_os_ioremap() is marked with __init because it calls memblock_
is_memory() which is also marked with __init in the !ARCH_KEEP_MEMBLOCK

as acpi_os_{read, write}_memory() and causes section mismatch warnings:

WARNING: modpost: vmlinux.o: section mismatch in reference: acpi_os_read_memory (section: .text) -> acpi_os_ioremap (section: .init.text)

removing the __init modifier of acpi_os_ioremap(). This can also give a

 "It's a lot smaller than last week, with the star of the show being a
  couple of fixes to head.S addressing a boot regression introduced by
  the recent overhaul of that code in non-default configurations (i.e.
  KASLR disabled).

  The first of those two resolves the issue reported (and bisected) by
  Mikulus in the wait_on_bit() thread.

  Summary:

   - Fix two boot issues caused by the recent head.S rework when !KASLR

   - Fix calculation of crashkernel memory reservation

   - Fix bogus error check in PMU IRQ probing code"
