Add a basic config to run kunit tests on LoongArch.
This requires QEMU 9.1.0 or later for the necessary direct kernel boot
support.

The alloc_string_stream() function only returns ERR_PTR(-ENOMEM) on
failure and never returns NULL. Therefore, switching the error check in
the caller from IS_ERR_OR_NULL to IS_ERR improves clarity, indicating
that this function will return an error pointer (not NULL) when an
error occurs. This change avoids any ambiguity regarding the function's
return behavior.

kunit_kzalloc() may return a NULL pointer, dereferencing it without
NULL check may lead to NULL dereference.
Add a NULL check for test_state.

In kunit_debugfs_create_suite(), if alloc_string_stream() fails in the
kunit_suite_for_each_test_case() loop, the "suite->log = stream"
has assigned before, and the error path only free the suite->log's stream
memory but not set it to NULL, so the later string_stream_clear() of
suite->log in kunit_init_suite() will cause below UAF bug.
Set stream pointer to NULL after free to fix it.

Currently if an fopen fails the error exit path is via code that
checks if fp is not null and closes the file, however, fp is null
so this check and close is redundant. Since the only use of the
err exit label is on the fopen check, remove it and replace the
code with a simple return of errno. Also remove variable rc since
it's no longer required.

Add flag --failed to kunit.py to print only failed tests. This printing
is done after running is over.
This patch also adds the method print_test() that will also print your
Test object. Before, all printing of tests occurred during parsing. This
method could be useful in the future when converting to/from KTAP to this
pretty-print output.

After a previous change, cpuidle_play_dead(), which is the only caller
of idle state :enter_dead() callbacks, ignores their return values, so
they may as well be void.

If the :enter_dead() idle state callback fails for a certain state,
there may be still a shallower state for which it will work.
Because the only caller of cpuidle_play_dead(), native_play_dead(),
falls back to hlt_play_dead() if it returns an error, it should
better try all of the idle states for which :enter_dead() is present
before failing, so change it accordingly.
Also notice that the :enter_dead() state callback is not expected
to return on success (the CPU should be "dead" then), so make
cpuidle_play_dead() ignore its return value.

Pull x86 SEV updates from Borislav Petkov:
- Do the proper memory conversion of guest memory in order to be able
to kexec kernels in SNP guests along with other adjustments and
cleanups to that effect
- Start converting and moving functionality from the sev-guest driver
into core code with the purpose of supporting the secure TSC SNP
feature where the hypervisor cannot influence the TSC exposed to the
guest anymore
- Add a "nosnp" cmdline option in order to be able to disable SNP
support in the hypervisor and thus free-up resources which are not
going to be used
- Cleanups

Pull RCU updates from Frederic Weisbecker:
"SRCU:
- Introduction of the new SRCU-lite flavour with a new pair of
srcu_read_[un]lock_lite() APIs. In practice the read side using
this flavour becomes lighter by removing a full memory barrier on
LOCK and a full memory barrier on UNLOCK. This comes at the expense
of a higher latency write side with two (in the best case of a
snaphot of unused read-sides) or more RCU grace periods on the
update side which now assumes by itself the whole full ordering
guarantee against the LOCK/UNLOCK counters on both indexes, along
with the accesses performed inside.
Uretprobes is a known potential user.
Note this doesn't replace the default normal flavour of SRCU which
still behaves the same as usual.
- Add testing of SRCU-lite through rcutorture and rcuscale
- Various cleanups on the way.
Fixes:
- Allow short-circuiting RCU-TASKS-RUDE grace periods on
architectures that have sane noinstr boundaries forbidding tracing
on low-level idle and kernel entry code. RCU-TASKS is enough on
such configurations because it involves an RCU grace period that
waits for all idle tasks to either schedule out voluntarily or
enter into RCU unwatched noinstr code.
- Allow and test start_poll_synchronize_rcu() with IRQs disabled.
- Mention rcuog kthreads in relevant documentation and Kconfig help
- Various fixes and consolidations
rcutorture:
- Add --no-affinity on tools to leave the affinity setting of guests
up to the user.
- Add guest_os_delay parameter to rcuscale for better warm-up
control.
- Fix and improve some rcuscale error handling.
- Various cleanups and fixes
stall:
- Remove dead code
- Stop dumping tasks if a stalled grace period eventually ended
midway as that only produces confusing output.
- Optimize detection of stalling CPUs and avoid useless node locking
otherwise.
NOCB:
- Fix rcu_barrier() hang due to a race against callbacks
deoffloading. This is not yet used, except by rcutorture, and waits
for its promised cpusets interface.
- Remove leftover function declaration"

Pull power management updates from Rafael Wysocki:
"The amd-pstate cpufreq driver gets the majority of changes this time.
They are mostly fixes and cleanups, but one of them causes it to
become the default cpufreq driver on some AMD server platforms.
Apart from that, the menu cpuidle governor is modified to not use
iowait any more, the intel_idle gets a custom C-states table for
Granite Rapids Xeon D, and the intel_pstate driver will use a more
aggressive Balance- performance default EPP value on Granite Rapids
now.

Specifics:
- Update the amd-pstate driver to set the initial scaling frequency
policy lower bound to be the lowest non-linear frequency (Dhananjay
Ugwekar)
- Enable amd-pstate by default on servers starting with newer AMD
Epyc processors (Swapnil Sapkal)

succeeds to always enforce sched domains rebuild in case EAS needs
to be enabled (Christian Loehle)
- Switch cpufreq back to platform_driver::remove() (Uwe Kleine-König)
- Use proper frequency unit names in cpufreq (Marcin Juszkiewicz)
- Add a built-in idle states table for Granite Rapids Xeon D to the
intel_idle driver (Artem Bityutskiy)
- Fix some typos in comments in the cpuidle core and drivers (Shen
Lichuan)
- Remove iowait influence from the menu cpuidle governor (Christian
Loehle)
- Add min/max available performance state limits to the Energy Model

This patch makes the dot parser used by dot2c and dot2k slightly more
robust, namely:
* allows parsing files with the gv extension (GraphViz)
* correctly parses edges with any indentation
* used to work only with a single character (e.g. '\t')
Additionally it fixes a couple of warnings reported by pylint such as
wrong indentation and comparison to False instead of `not ...`

The enhancements made to timerlat_load.py are intended to improve the script's exception handling.
Summary of the changes:
- Specific exceptions are now caught for CPU affinity and priority
settings, with clearer error messages provided.
- The timerlat file descriptor opening now includes handling for
PermissionError and OSError, with informative messages.
- In the infinite loop, generic exceptions have been replaced with
specific types like KeyboardInterrupt and IOError, improving feedback.
Before:
$ sudo python timerlat_load.py 122

The enhancements made to timerlat_load.py are aimed at improving the clarity of argument parsing.
Summary of Changes:
- The cpu argument is now specified as an integer type in the argument
parser to enforce input validation, and the construction of affinity_mask
has been simplified to directly use the integer value of args.cpu.
- The prio argument is similarly updated to be of integer type for
consistency and validation, eliminating the need for the conversion of
args.prio to an integer, as this is now handled by the argument parser.

Since commit fb9e90a67ee9 ("rtla/timerlat: Make user-space threads
the default"), rtla-timerlat has been defaulting to
params->user_workload if neither that or params->kernel_workload is set.
This has unintentionally made -U, which sets only params->user_hist/top
but not params->user_workload, to behave like -u unless -k is set,
preventing the user from running a custom workload.
Example:
$ rtla timerlat hist -U -c 0 &
[1] 7413
$ python sample/timerlat_load.py 0
Error opening timerlat fd, did you run timerlat -U?
$ ps | grep timerlatu
7415 pts/4 00:00:00 timerlatu/0
Fix the issue by checking for params->user_top/hist instead of
params->user_workload when setting default thread mode.

page_frag test module is an out of tree module, but built
using KDIR as the main kernel tree, the mm test suite is
just getting skipped if newly added page_frag test module
fails to compile due to kernel not yet compiled.
Fix the above problem by ensuring both kernel is built first
and a newer kernel which has page_frag_cache.h is used.

git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux into mtd/next
SPI NOR introduces byte swap support for 8D-8D-8D mode and a user for
it: macronix. SPI NOR flashes may swap the bytes on a 16-bit boundary
when configured in Octal DTR mode. For such cases the byte order is
propagated through SPI MEM to the SPI controllers so that the controllers
swap the bytes back at runtime. This avoids breaking the boot sequence
because of the endianness problems that appear when the bootloaders use
1-1-1 and the kernel uses 8D-8D-8D with byte swap support. Along with the
SPI MEM byte swap support we queue a patch for the SPI MXIC controller
that swaps the bytes back at runtime.
