bw_report is always set to "reads" and bm_type is set to "fill_buf" but
is never used.
Set bw_report directly to "reads" in MBA/MBM test and remove bm_type.

Benchmark command must be the last argument because it consumes all the
remaining arguments but help misleadingly shows it as the first
argument. The benchmark command is also shown in quotes but it does not
match with the code.
Correct -b argument place in the help message and remove the quotes.
Tweak also how the options are presented by using ... notation.

Benchmark command is copied into an array in the stack. The array is
BENCHMARK_ARGS items long but the command line could try to provide a
longer command. Argument size is also fixed by BENCHMARK_ARG_SIZE (63
bytes of space after fitting the terminating \0 character) and user
could have inputted argument longer than that.
Return error in case the benchmark command does not fit to the space
allocated for it.

Kselftest header defines multiple variadic functions that use printf
along with other logic.
There is no format checking for the variadic functions that use
printing inside kselftest.h. Because of this the compiler won't
be able to catch instances of mismatched printf formats and debugging
tests might be more difficult.
Add the common __printf() attribute macro to kselftest.h.
Add __printf() attribute to every function using formatted printing
with variadic arguments.
Adding the attribute and compiling all selftests exposes a number of
-Wformat warnings which were previously unnoticed due to a lack of
format specifiers checking by the compiler.

Currently the bpf selftests are skipped by default, so is someone would
like to run the tests one would need to run:
$ make TARGETS=bpf SKIP_TARGETS="" kselftest
To overwrite the SKIP_TARGETS that defines bpf by default. Also,
following the BPF instructions[1], to run the bpf selftests one would
need to enter in the tools/testing/selftests/bpf/ directory, and then
run make, which is not the standard way to run selftests per it's
documentation.
For the reasons above stop mentioning bpf in the kselftests as examples
of how to run a test suite.

The ret variable is used to check function return values and assigning
values to it on error has no effect as it is an unused value.
The current implementation uses an additional variable (fret) to return
the error value, which in this case is unnecessary and lead to the above
described misuse. There is no restriction in the current implementation
to always return -1 on error and the actual negative error value can be
returned safely without storing -1 in a specific variable.
Simplify the error checking by using a single variable which always
holds the returned value.

The kselftest-merge target walks all kselftests configs, and merges
them. However, builtin does not have precedence over modules. This
breaks some of the tests, e.g.:
$ grep CONFIG_NF_NAT tools/testing/selftests/{bpf,net}/config
tools/testing/selftests/bpf/config:CONFIG_NF_NAT=y
tools/testing/selftests/net/config:CONFIG_NF_NAT=m
Here, the net config will set NF_NAT to module, which makes it clunky
to run the BPF tests.
Add '-y' to scripts/kconfig/merge_config.sh.

When building with Clang, I am getting many warnings from the selftests/rseq tree.
Here's one such example from rseq tree:
| param_test.c:1234:10: error: address argument to atomic operation must be a pointer to _Atomic type ('intptr_t *' (aka 'long *') invalid)
| 1234 | while (!atomic_load(&args->percpu_list_ptr)) {}
| | ^ ~~~~~~~~~~~~~~~~~~~~~~
| /usr/local/google/home/justinstitt/repos/tc-build/build/llvm/final/lib/clang/18/include/stdatomic.h:140:29: note: expanded from macro 'atomic_load'
| 140 | #define atomic_load(object) __c11_atomic_load(object, __ATOMIC_SEQ_CST)
| | ^ ~~~~~~
Use compiler builtins `__atomic_load_n()` and `__atomic_store_n()` with
accompanying __ATOMIC_ACQUIRE and __ATOMIC_RELEASE, respectively. This
will fix the warnings because the compiler builtins do not expect their
arguments to have _Atomic type. This should also make TSAN happier.

The choose_32_64() macros were added to deal with an odd inconsistency
between the 32-bit and 64-bit layout of 'struct stat' way back when in
commit a52dd971f947 ("vfs: de-crapify "cp_new_stat()" function").
Then a decade later Mikulas noticed that said inconsistency had been a
mistake in the early x86-64 port, and shouldn't have existed in the
first place. So commit 932aba1e1690 ("stat: fix inconsistency between
struct stat and struct compat_stat") removed the uses of the helpers.
But the helpers remained around, unused.

The decompressor has a hard limit on the number of page tables it can
allocate. This limit is defined at compile-time and will cause boot
failure if it is reached.
The kernel is very strict and calculates the limit precisely for the
worst-case scenario based on the current configuration. However, it is
easy to forget to adjust the limit when a new use-case arises. The
worst-case scenario is rarely encountered during sanity checks.
In the case of enabling 5-level paging, a use-case was overlooked. The
limit needs to be increased by one to accommodate the additional level.
This oversight went unnoticed until Aaron attempted to run the kernel
via kexec with 5-level paging and unaccepted memory enabled.
Update wost-case calculations to include 5-level paging.
To address this issue, let's allocate some extra space for page tables.
128K should be sufficient for any use-case. The logic can be simplified
by using a single value for all kernel configurations.
[ Also add a warning, should this memory run low - by Dave Hansen. ]

Commit 408579cd627a ("mm: Update do_vmi_align_munmap() return
semantics") seems to have updated one of the callers of do_vmi_munmap()
incorrectly: it used to check for the error case (which didn't
change: negative means error).
That commit changed the check to the success case (which did change:
before that commit, 0 was success, and 1 was "success and lock
downgraded". After the change, it's always 0 for success, and the lock
will have been released if requested).
This didn't change any actual VM behavior _except_ for memory accounting
when 'VM_ACCOUNT' was set on the vma. Which made the wrong return value
test fairly subtle, since everything continues to work.
Or rather - it continues to work but the "Committed memory" accounting
goes all wonky (Committed_AS value in /proc/meminfo), and depending on
settings that then causes problems much much later as the VM relies on
bogus statistics for its heuristics.
Revert that one line of the change back to the original logic.

Pull ata fixes from Damien Le Moal:
- Fix link power management transitions to disallow unsupported states
(Niklas)
- A small string handling fix for the sata_mv driver (Christophe)
- Clear port pending interrupts before reset, as per AHCI
specifications (Szuying).
Followup fixes for this one are to not clear ATA_PFLAG_EH_PENDING in
ata_eh_reset() to allow EH to continue on with other actions recorded
with error interrupts triggered before EH completes. And an
additional fix to avoid thawing a port twice in EH (Niklas)
- Small code style fixes in the pata_parport driver to silence the
build bot as it keeps complaining about bad indentation (me)
- A fix for the recent CDL code to avoid fetching sense data for
successful commands when not necessary for correct operation (Niklas)

Currently, we fetch sense data for a _successful_ command if 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.
This means that case 2) will trigger for a non-NCQ command which has
ATA_SENSE bit set, regardless if CDL is enabled or not.
This decision was by design. If the device reports that it has sense data
available, it makes sense to fetch that sense data, since the sk/asc/ascq
could be important information regardless if CDL is enabled or not.
However, the fetching of sense data for a successful command is done via
ATA EH. Considering how intricate the ATA EH is, we really do not want to
invoke ATA EH unless absolutely needed.
Before commit 18bd7718b5c4 ("scsi: ata: libata: Handle completion of CDL
commands using policy 0xD") we never fetched sense data for successful
commands.
In order to not invoke the ATA EH unless absolutely necessary, even if the
device claims support for sense data reporting, only fetch sense data for
successful (NCQ and non-NCQ commands) commands that are using CDL.
[Damien] Modified the check to test the qc flag ATA_QCFLAG_HAS_CDL
instead of the device support for CDL, which is implied for commands
using CDL.

commit 1e641060c4b5 ("libata: clear eh_info on reset completion") added
a workaround that broke the retry mechanism in ATA EH.
Tejun himself suggested to remove this workaround when it was identified
to cause additional problems:
https://lore.kernel.org/linux-ide/20110426135027.GI878@htj.dyndns.org/
He even said:
"Hmm... it seems I wasn't thinking straight when I added that work around."
https://lore.kernel.org/linux-ide/20110426155229.GM878@htj.dyndns.org/
While removing the workaround solved the issue, however, the workaround was
kept to avoid "spurious hotplug events during reset", and instead another
workaround was added on top of the existing workaround in commit
8c56cacc724c ("libata: fix unexpectedly frozen port after ata_eh_reset()").
Because these IRQs happened when the port was frozen, we know that they
were actually a side effect of PxIS and IS.IPS(x) not being cleared before
the COMRESET. This is now done in commit 94152042eaa9 ("ata: libahci: clear
pending interrupt status"), so these workarounds can now be removed.
Since commit 1e641060c4b5 ("libata: clear eh_info on reset completion") has
now been reverted, the ATA EH retry mechanism is functional again, so there
is once again no need to thaw the port more than once in ata_eh_reset().
This reverts "the workaround on top of the workaround" introduced in commit
8c56cacc724c ("libata: fix unexpectedly frozen port after ata_eh_reset()").
