1a4a993cc2 media: mmc: siano: simplify module initialization
This driver's initialization functions do not perform any custom code,
except printing messages.  Printing messages on modules
loading/unloading is discouraged because it pollutes the dmesg
regardless whether user actually has this device.  Core kernel code
already gives tools to investigate whether module was loaded or not.

Drop the printing messages which allows to replace open-coded
module_sdio_driver().

b1f3677aeb media: staging: media: starfive: camss: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

3c2ea5ec1d media: anysee: accept read buffers of length 1 in anysee_master_xfer
anysee_master_xfer currently accepts read messages of length 2 only.
However, several frontends, e.g. tda10023 send buffers of length 1,
containing an 8-bit register number (see tda10023_readreg).
These buffers are rejected currently, making many Anysee variants
to not work. In these cases the "Unsupported Anysee version"
message is logged.

This patch alters the function to accept buffers of a length of 1 too.

commit 691632f0e8 ("Merge tag 's390-6.9-1' of
git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux"), s390 can be
built with LLVM=1 when using LLVM 18.1.0, which is the first version
that has SystemZ support implemented in ld.lld and llvm-objcopy.

Update the supported architectures table in the Kbuild LLVM
documentation to note this explicitly to make it more discoverable by
users and other developers. Additionally, this brings s390 in line with
the rest of the architectures in the table, which all support LLVM=1.

54babdc034 kbuild: Disable KCSAN for autogenerated *.mod.c intermediaries
When KCSAN and CONSTRUCTORS are enabled, one can trigger the

  "Unpatched return thunk in use. This should not happen!"

catch-all warning.

Usually, when objtool runs on the .o objects, it does generate a section
.return_sites which contains all offsets in the objects to the return
thunks of the functions present there. Those return thunks then get
patched at runtime by the alternatives.

KCSAN and CONSTRUCTORS add this to the object file's .text.startup
section:

  -------------------
  Disassembly of section .text.startup:

  ...

  0000000000000010 <_sub_I_00099_0>:
    10:   f3 0f 1e fa             endbr64
    14:   e8 00 00 00 00          call   19 <_sub_I_00099_0+0x9>
                          15: R_X86_64_PLT32      __tsan_init-0x4

  -------------------

which, if it is built as a module goes through the intermediary stage of
creating a <module>.mod.c file which, when translated, receives a second
constructor:

  -------------------
  Disassembly of section .text.startup:

  0000000000000010 <_sub_I_00099_0>:
    10:   f3 0f 1e fa             endbr64

                          1a: R_X86_64_PLT32      __x86_return_thunk-0x4

  ...

  0000000000000030 <_sub_I_00099_0>:
    30:   f3 0f 1e fa             endbr64

                          3a: R_X86_64_PLT32      __x86_return_thunk-0x4
  -------------------

in the .ko file.

Objtool has run already so that second constructor's return thunk cannot
be added to the .return_sites section and thus the return thunk remains
unpatched and the warning rightfully fires.

Drop KCSAN flags from the mod.c generation stage as those constructors
do not contain data races one would be interested about.

c40845e319 kbuild: make -Woverride-init warnings more consistent
The -Woverride-init warn about code that may be intentional or not,
but the inintentional ones tend to be real bugs, so there is a bit of
disagreement on whether this warning option should be enabled by default
and we have multiple settings in scripts/Makefile.extrawarn as well as
individual subsystems.

Older versions of clang only supported -Wno-initializer-overrides with
the same meaning as gcc's -Woverride-init, though all supported versions
now work with both. Because of this difference, an earlier cleanup of
mine accidentally turned the clang warning off for W=1 builds and only
left it on for W=2, while it's still enabled for gcc with W=1.

There is also one driver that only turns the warning off for newer
versions of gcc but not other compilers, and some but not all the
Makefiles still use a cc-disable-warning conditional that is no
longer needed with supported compilers here.

Address all of the above by removing the special cases for clang
and always turning the warning off unconditionally where it got
in the way, using the syntax that is supported by both compilers.

fe764a75cf SCSI fixes on 20240330
Fully half this pull is updates to lpfc and qla2xxx which got
 committed just as the merge window opened.  A sizeable fraction of the
 driver updates are simple bug fixes (and lock reworks for bug fixes in
 the case of lpfc), so rather than splitting the few actual
 enhancements out, we're just adding the drivers to the -rc1 pull.  The
 enhancements for lpfc are log message removals, copyright updates and
 three patches redefining types.  For qla2xxx it's just removing a
 debug message on module removal and the manufacturer detail update.
 
 The two major fixes are the sg teardown race and a core error leg
 problem with the procfs directory not being removed if we destroy a
 created host that never got to the running state.  The rest are minor
 fixes and constifications.

3f1a9bc5d8 x86/build: Use obj-y to descend into arch/x86/virt/
Commit c33621b4c5 ("x86/virt/tdx: Wire up basic SEAMCALL functions")
introduced a new instance of core-y instead of the standardized obj-y
syntax.

X86 Makefiles descend into subdirectories of arch/x86/virt inconsistently;
into arch/x86/virt/ via core-y defined in arch/x86/Makefile, but into
arch/x86/virt/svm/ via obj-y defined in arch/x86/Kbuild.

This is problematic when you build a single object in parallel because
multiple threads attempt to build the same file.

  $ make -j$(nproc) arch/x86/virt/vmx/tdx/seamcall.o
    [ snip ]
    AS      arch/x86/virt/vmx/tdx/seamcall.o
    AS      arch/x86/virt/vmx/tdx/seamcall.o
  fixdep: error opening file: arch/x86/virt/vmx/tdx/.seamcall.o.d: No such file or directory
  make[4]: *** [scripts/Makefile.build:362: arch/x86/virt/vmx/tdx/seamcall.o] Error 2

Use the obj-y syntax, as it works correctly.

7155cc4544 selftests/seccomp: Try to fit runtime of benchmark into timeout
The seccomp benchmark runs five scenarios, one calibration run with no
seccomp filters enabled then four further runs each adding a filter. The
calibration run times itself for 15s and then each additional run executes
for the same number of times.

Currently the seccomp tests, including the benchmark, run with an extended
120s timeout but this is not sufficient to robustly run the tests on a lot
of platforms. Sample timings from some recent runs:

   Platform          Run 1  Run 2  Run 3  Run 4
   ---------         -----  -----  -----  -----
   PowerEdge R200    16.6s  16.6s  31.6s  37.4s
   BBB (arm)         20.4s  20.4s  54.5s
   Synquacer (arm64) 20.7s  23.7s  40.3s

The x86 runs from the PowerEdge are quite marginal and routinely fail, for
the successful run reported here the timed portions of the run are at
117.2s leaving less than 3s of margin which is frequently breached. The
added overhead of adding filters on the other platforms is such that there
is no prospect of their runs fitting into the 120s timeout, especially
on 32 bit arm where there is no BPF JIT.

While we could lower the time we calibrate for I'm also already seeing the
currently completing runs reporting issues with the per filter overheads
not matching expectations:

Let's instead raise the timeout to 180s which is only a 50% increase on the
current timeout which is itself not *too* large given that there's only two
tests in this suite.

8ecab2e645 selftests/ftrace: Fix event filter target_func selection
The event filter function test has been failing in our internal test
farm:

| # not ok 33 event filter function - test event filtering on functions

Running the test in verbose mode indicates that this is because the test
erroneously determines that kmem_cache_free() is the most common caller
of kmem_cache_free():

  # # + cut -d: -f3 trace
  # # + sed s/call_site=([^+]*)+0x.*/1/
  # # + sort
  # # + uniq -c
  # # + sort
  # # + tail -n 1
  # # + sed s/^[ 0-9]*//
  # # + target_func=kmem_cache_free

... and as kmem_cache_free() doesn't call itself, setting this as the
filter function for kmem_cache_free() results in no hits, and
consequently the test fails:

  # # + grep kmem_cache_free trace
  # # + grep kmem_cache_free
  # # + wc -l
  # # + hitcnt=0
  # # + grep kmem_cache_free trace
  # # + grep -v kmem_cache_free
  # # + wc -l
  # # + misscnt=0
  # # + [ 0 -eq 0 ]
  # # + exit_fail

This seems to be because the system in question has tasks with ':' in
their name (which a number of kernel worker threads have). These show up
in the trace, e.g.

  test:.sh-1299    [004] .....  2886.040608: kmem_cache_free: call_site=putname+0xa4/0xc8 ptr=000000000f4d22f4 name=names_cache

... and so when we try to extact the call_site with:

  cut -d: -f3 trace | sed 's/call_site=\([^+]*\)+0x.*/\1/'

... the 'cut' command will extrace the column containing
'kmem_cache_free' rather than the column containing 'call_site=...', and
the 'sed' command will leave this unchanged. Consequently, the test will
decide to use 'kmem_cache_free' as the filter function, resulting in the
failure seen above.

Fix this by matching the 'call_site=<func>' part specifically to extract
the function name.

4535e1a417 x86/bugs: Fix the SRSO mitigation on Zen3/4
The original version of the mitigation would patch in the calls to the
untraining routines directly.  That is, the alternative() in UNTRAIN_RET
will patch in the CALL to srso_alias_untrain_ret() directly.

However, even if commit e7c25c441e ("x86/cpu: Cleanup the untrain
mess") meant well in trying to clean up the situation, due to micro-
architectural reasons, the untraining routine srso_alias_untrain_ret()
must be the target of a CALL instruction and not of a JMP instruction as
it is done now.

Reshuffle the alternative macros to accomplish that.
