mmc: renesas_sdhi: Set the SDBUF after reset
For development purpose, renesas_sdhi_probe() could be called w/
dma_ops = NULL to force the usage of PIO mode. In this case the
renesas_sdhi_enable_dma() will not be called before transferring data.
If renesas_sdhi_enable_dma() is not called, renesas_sdhi_clk_enable()
call from renesas_sdhi_probe() will configure SDBUF by calling the
renesas_sdhi_sdbuf_width() function, but then SDBUF will be reset in
tmio_mmc_host_probe() when calling tmio_mmc_reset() though host->reset().
If SDBUF is zero the data transfer will not work in PIO mode for RZ/G3S.

renesas_sdhi_reset(). The call of renesas_sdhi_sdbuf_width() was not
removed from renesas_sdhi_clk_enable() as the host->reset() is optional.

mmc: sdhci-acpi: Add quirk to enable pull-up on the card-detect GPIO on Asus T100TA
The card-detect GPIO for the microSD slot on Asus T100TA / T100TAM models
stopped working under Linux after commit
6fd03f024828 ("gpiolib: acpi:
support bias pull disable").
The GPIO in question is connected to a mechanical switch in the slot
which shorts the pin to GND when a card is inserted.
The GPIO pin correctly gets configured with a 20K pull-up by the BIOS,
but there is a bug in the DSDT where the GpioInt for the card-detect is
configured with a PullNone setting:
GpioInt (Edge, ActiveBoth, SharedAndWake, PullNone, 0x2710,
"\\_SB.GPO0", 0x00, ResourceConsumer, ,
)
{ // Pin list
0x0026
}
Linux now actually honors the PullNone setting and disables the 20K pull-up
configured by the BIOS.
Add a new DMI_QUIRK_SD_CD_ENABLE_PULL_UP quirk which when set calls
mmc_gpiod_set_cd_config() to re-enable the pull-up and set this for
the Asus T100TA models to fix this.

memstick: rtsx_usb_ms: 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.

mmc: sdio: store owner from modules with sdio_register_driver()
Modules registering driver with sdio_register_driver() might
forget to set .owner field. The field is used by some of other kernel
parts for reference counting (try_module_get()), so it is expected that
drivers will set it.
Solve the problem by moving this task away from the drivers to the core
code, just like we did for platform_driver in
commit
9447057eaff8 ("platform_device: use a macro instead of
platform_driver_register").
Since many drivers forget to set the .owner, this effectively will fix
them. Examples of fixed drivers are: ath6kl, b43, btsdio.c, ks7010,
libertas, MediaTek WiFi drivers, Realtek WiFi drivers, rsi, siano,

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:
...

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.

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.

c33621b4c5ad ("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.

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.

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.

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
e7c25c441e9e ("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.

mm: clean up populate_vma_page_range() FOLL_* flag handling
The code wasn't exactly wrong, but it was very odd, and it used
FOLL_FORCE together with FOLL_WRITE when it really didn't need to (it
only set FOLL_WRITE for writable mappings, so then the FOLL_FORCE was
pointless).
It also pointlessly called __get_user_pages() even when it knew it
wouldn't populate anything because the vma wasn't accessible and it
explicitly tested for and did *not* set FOLL_FORCE for inaccessible
vma's.
This code does need to use FOLL_FORCE, because we want to do fault in
writable shared mappings, but then the mapping may not actually be
readable. And we don't want to use FOLL_WRITE (which would match the
permission of the vma), because that would also dirty the pages, which
we don't want to do.
For very similar reasons, FOLL_FORCE populates a executable-only mapping
with no read permissions. We don't have a FOLL_EXEC flag.
Yes, it would probably be cleaner to split FOLL_WRITE into two bits (for
separate permission and dirty bit handling), and add a FOLL_EXEC flag
for the "GUP executable page" case. That would allow us to avoid
FOLL_FORCE entirely here.
But that's not how our FOLL_xyz bits have traditionally worked, and that
would be a much bigger patch.
So this at least avoids the FOLL_FORCE | FOLL_WRITE combination that
made one of my experimental validation patches trigger a warning. That
warning was a false positive (and my experimental patch was incomplete
anyway), but it all made me look at this and decide to clean at least
this small case up.
