The memset() in hid_report_raw_event() has the good intention of
clearing out bogus data by zeroing the area from the end of the incoming
data string to the assumed end of the buffer. However, as we have
previously seen, doing so can easily result in OOB reads and writes in
the subsequent thread of execution.
The current suggestion from one of the HID maintainers is to remove the
memset() and simply return if the incoming event buffer size is not
large enough to fill the associated report.

The comparison of an __s8 value against DTPAGEMAXSLOT is still trivially
true, causing a harmless (default disabled) warning with clang:

I previously worked around two of these in commit 7833570dae ("jfs: avoid

come up, so address the same way by dropping the redundant range check.

The "keep-power-in-suspend", "wakeup-source" and "enable-sdio-wakeup"
properties are already parsed in mmc_of_parse(). All sdhci drivers that
call sdhci_get_property() also call mmc_of_parse(). The only exception
is sdhci-of-hlwd, which does not call mmc_of_parse(), but its devicetree

When 1-bit bus width is used with HS200/HS400 capabilities set,
mmc_select_hs200() returns 0 without actually switching. This
causes mmc_select_timing() to skip mmc_select_hs(), leaving eMMC
in legacy mode (26MHz) instead of High Speed SDR (52MHz).
Per JEDEC eMMC spec section 5.3.2, 1-bit mode supports High Speed
SDR. Drop incompatible HS200/HS400/UHS/DDR caps early so timing
selection falls through to mmc_select_hs() correctly.

The bus width support for UHS mode is now validated in mmc_validate_host_caps().
Therefore, we can safely remove the explicit MMC_CAP_4_BIT_DATA check from
mmc_host_can_uhs(). As part of this cleanup, simplify the condition by using
the consolidated MMC_CAP_UHS flag.

UHS/DDR/HS200 modes require at least 4-bit bus support. Host controllers
that lack relevant capability registers rely on paring properties provided
by firmware, which may incorrectly set these modes. Now that mmc_validate_host_caps()
has been introduced to validate such configuration violations, let's also
add checks for UHS/DDR/HS200 modes.
This fixes an issue where, if the HS200/HS400 property is set while only
a 1-bit bus width is used, mmc_select_hs200() returns 0 without actually
performing the mode switch. Consequently, mmc_select_timing() proceeds
without falling back to mmc_select_hs(), leaving the eMMC device operating
in legacy mode (26 MHz) instead of switching to High Speed mode (52 MHz).

setup_fifo_params computes mode_changed from spi->mode flags but tests
it against SE_SPI_CPHA and SE_SPI_CPOL, which are register offsets,
not SPI mode bits. This causes CPHA and CPOL updates to be skipped
on mode switches, leaving the controller with stale clock phase
and polarity settings.
Fix this by using SPI_CPHA and SPI_CPOL to detect mode changes before
updating the corresponding registers.

Because old pcm_new()/pcm_free() didn't care about parameter component,
to avoid name collisions, we have added pcm_construct()/pcm_destruct() by
commit c64bfc9066 ("ASoC: soc-core: add new pcm_construct/pcm_destruct")
Because all driver switch to new pcm_construct()/pcm_destruct(), old
pcm_new()/pcm_free() were remoted by commit e9067bb502 ("ASoC:

But naming of pcm_construct()/pcm_destruct() are not goot. re-add
pcm_new()/pcm_free(), and switch to use it, again.
Because it has no functional significance, 1 patch is for 1 vender.

We have been used pcm_new()/pcm_free(), but switched to
pcm_construct()/pcm_destruct() to use extra parameters [1].
pcm_new()/free() had been removed [2], but each drivers are still
using such function naming. Let's name back to pcm_new()/pcm_free()
again.

Because old pcm_new()/pcm_free() didn't care about parameter component,
to avoid name collisions, we have added pcm_construct()/pcm_destruct() by
commit c64bfc9066 ("ASoC: soc-core: add new pcm_construct/pcm_destruct")
Because all driver switch to new pcm_construct()/pcm_destruct(), old
pcm_new()/pcm_free() were remoted by commit e9067bb502 ("ASoC:
soc-component: remove snd_pcm_ops from component driver")
But naming of pcm_construct()/pcm_destruct() are not goot. re-add
pcm_new()/pcm_free(), and switch to use it, again.

The function allocates and then refills and empty sheaf. It's only
called from __pcs_replace_empty_main(), which can also in some cases
refill an empty sheaf. We can therefore consolidate this code.
Remove alloc_full_sheaf() and refactor __pcs_replace_empty_main() so it
will call alloc_empty_sheaf() when necessary, and then use the
pre-existing refill_sheaf(). The result should be simpler to follow and
less duplicated code.
Also adjust the comment about returning sheaves to barn, the part about
where the empty sheaf we'd be returning comes from is incorrect.
No functional change intended.

This converts the Arizona driver to use GPIO descriptors
exclusively, deletes the legacy code path an updates the
in-tree user of legacy GPIO.
The GPIO lines for mic detect polarity and headphone ID
detection are made exclusively descriptor-oriented. The
headphone ID detection could actually only be used by
the legacy GPIO code, but I converted it to use a
descriptor if someone would actually need it so we don't
just drop useful code.
The compatible "wlf,hpdet-id-gpio" is not in the device
tree bindings and only intended to be used by software
nodes if any. If someone insists I can try to add a
binding for it, but I doubt there is any real user so
it seems pointless.

The current clang thin-lto build often produces lots of symbols with
suffix. The following is a partial list of such function call symbols:
...
ethnl_module_fw_flash_ntf.llvm.7631589765585346066
__nf_conntrack_alloc.llvm.6438426151906658917
tcp_can_early_drop.llvm.11937612064648250727
tcp_print_conntrack.llvm.11937612064648250727
...
In my particular build with current bpf-next, the number of '*.llvm.<hash>'
function calls is 1212. As the side effect of cross-file inlining,
some static variables may be promoted with '*.llvm.<hash>' as well.
In my same setup, the number of variables with such suffixes is 9.
Such symbols make kernel live patching difficult since
- a minor code change will change the hash and then the '*.llvm.<hash>'
symbol becomes another one with a different hash. Sometimes, maybe
the suffix is gone.
- a previous source-level symbol may become a one with suffix after live
patching code.
In [1], Song Liu suggested to reduce the number of '*.llvm.<hash>' functions
to make live patch easier. In respond of this, I implemented this
in llvm ([2]). The same thin-lto build with [2] only has two symbols with
suffix:
m_stop.llvm.14460341347352036579
m_next.llvm.14460341347352036579
This should make live patch much easier.
To support suffix symbol reduction, two lld flags are necessary to enable
this feature in kernel:
- Flag '--lto-whole-program-visibility' is needed as it ensures that all
non-assembly files are available in the same thin-lto lld, which is true
for kernel.
- Flag '-mllvm -always-rename-promoted-locals=false' is needed to enable
suffix reduction. Currently in llvm [1], only process mode is supported.
There is another distributed mode (across different processes or even
different machines) which is not supported yet ([2]). The kernel uses
process mode so it should work.
The assembly files may have some global functions/data which may potentially
conflict with thin-lto global symbols after the above two flags. But such assembly
global symbols are limited and tend to be uniquely named for its context.
Hence the conflict with globals in non-assembly codes is rare. If indeed the
conflict happens, we can rename either of them to avoid conflicts.
Nathan Chancellor suggested the following under thin-lto:
KBUILD_LDFLAGS += $(call ld-option,--lto-whole-program-visibility -mllvm -always-rename-promoted-locals=false)
The '-mllvm -always-rename-promoted-locals=false' flag is only available for llvm23.
So for llvm22 or earlier, the above KBUILD_LDFLAGS will ignore those two flags.
For llvm23 and later, two flags will be added to KBUILD_LDFLAGS.
