Commit a2225d93 ("autofs: remove left-over autofs4 stubs")
promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS
within a couple of releases, but five years later this still has not
happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs.

Get rid of it mechanically:

   git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' |
       xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/'

Also just remove the AUTOFS4_FS config option stub.  Anybody who hasn't
regenerated their config file in the last five years will need to just
get the new name right when they do.

recv_data either returns the number of received bytes, or a negative value
representing an error code. Adding the return value directly to the total
number of received bytes therefore looks a little weird, since it might add
a negative error code to a sum of bytes.

The following check for size < expected usually makes the function return
ETIME in that case, so it does not cause too many problems in practice. But
to make the code look cleaner and because the caller might still be
interested in the original error code, explicitly check for the presence of
an error code and pass that through.

Doing the full reset will remove the false positives, but will allow
late use of memblock_free() to go unnoticed, so it is better to revert

mbind() calls down into vma_replace_policy() without taking the per-VMA
locks, replaces the VMA's vma->vm_policy pointer, and frees the old
policy.  That's bad; a concurrent page fault might still be using the
old policy (in vma_alloc_folio()), resulting in use-after-free.

Normally this will manifest as a use-after-free read first, but it can
result in memory corruption, including because vma_alloc_folio() can
call mpol_cond_put() on the freed policy, which conditionally changes
the policy's refcount member.

This bug is specific to CONFIG_NUMA, but it does also affect non-NUMA
systems as long as the kernel was built with CONFIG_NUMA.

According to the ARM IORT specifications DEN 0049 issue E,
the "Number of IDs" field in the ID mapping format reports
the number of IDs in the mapping range minus one.

In iort_node_get_rmr_info(), we erroneously skip ID mappings
whose "Number of IDs" equal to 0, resulting in valid mapping
nodes with a single ID to map being skipped, which is wrong.

Fix iort_node_get_rmr_info() by removing the bogus id_count
check.

This patch fixes an underflow issue in the return value within the
exception path, specifically at .Llt8 when the remaining length is less
than 8 bytes.

On FDT systems these command line processing are already taken care of
by early_init_dt_scan_chosen(). Add similar handling to the ACPI (non-
FDT) code path to allow these config options to work for ACPI (non-FDT)
systems too.

Binutils 2.41 enables linker relaxation by default, but the kernel
module loader doesn't support that, so just disable it. Otherwise we
get such an error when loading modules:

"Unknown relocation type 102"

As an alternative, we could add linker relaxation support in the kernel
module loader. But it is relatively large complexity that may or may not
bring a similar gain, and we don't really want to include this linker
pass in the kernel.

This is a port of commit 4fe4a637 ("MIPS: Only fiddle with
CHECKFLAGS if `need-compiler'") to LoongArch.

We have originally guarded fiddling with CHECKFLAGS in our arch Makefile
by checking for the CONFIG_LOONGARCH variable, not set for targets such
as `distclean', etc. that neither include `.config' nor use the compiler.

Starting from commit 805b2e1d ("kbuild: include Makefile.compiler
only when compiler is needed") we have had a generic `need-compiler'
variable explicitly telling us if the compiler will be used and thus its
capabilities need to be checked and expressed in the form of compilation
flags.  If this variable is not set, then `make' functions such as
`cc-option' are undefined, causing all kinds of weirdness to happen if
we expect specific results to be returned.

It doesn't cause problems on LoongArch now. But as a guard we replace
the check for CONFIG_LOONGARCH with one for `need-compiler' instead, so
as to prevent the compiler from being ever called for CHECKFLAGS when
not needed.

The condition to fetch sense data was supposed to be:
ATA_SENSE set AND either
1) Command was NCQ and ATA_DFLAG_CDL_ENABLED flag set (flag
   ATA_DFLAG_CDL_ENABLED will only be set if the Successful NCQ command
   sense data supported bit is set); or
2) Command was non-NCQ and regular sense data reporting is enabled.

However the check in 2) accidentally had the negation at the wrong place,
causing it to try to fetch sense data if it was a non-NCQ command _or_
if regular sense data reporting was _not_ enabled.

Fix this by removing the extra parentheses that should not be there,
such that only the correct return (ata_is_ncq()) is negated.

It was pointed out[1] that using folio_test_hwpoison() is wrong as we need
to check the indiviual page that has poison.  folio_test_hwpoison() only
checks the head page so go back to using PageHWPoison().

User-visible effects include existing hwpoison-inject tests possibly
failing as unpoisoning a single subpage could lead to unpoisoning an
entire folio.  Memory unpoisoning could also not work as expected as
the function will break early due to only checking the head page and
not the actually poisoned subpage.
