Prior to this, commit 4cd12c6065df ("bpf, sockmap: Fix NULL pointer
dereference in sk_psock_verdict_data_ready()") fixed one NULL pointer
similarly due to no protection of saved_data_ready. Here is another
different caller causing the same issue because of the same reason. So
we should protect it with sk_callback_lock read lock because the writer
side in the sk_psock_drop() uses "write_lock_bh(&sk->sk_callback_lock);".
To avoid errors that could happen in future, I move those two pairs of
lock into the sk_psock_data_ready(), which is suggested by John Fastabend.

Turns out that due to CONFIG_DEBUG_INFO_BTF_MODULES not having an
explicitly specified "menu item name" in Kconfig, it's basically
impossible to turn it off (see [0]).
This patch fixes the issue by defining menu name for
CONFIG_DEBUG_INFO_BTF_MODULES, which makes it actually adjustable
and independent of CONFIG_DEBUG_INFO_BTF, in the sense that one can
have DEBUG_INFO_BTF=y and DEBUG_INFO_BTF_MODULES=n.
We still keep it as defaulting to Y, of course.

The devm_regulator_get_enable_optional() should be a 'call and forget'
API, meaning, when it is used to enable the regulators, the API does not
provide a handle to do any further control of the regulators. It gives
no real benefit to return an error from the stub if CONFIG_REGULATOR is
not set.
On the contrary, returning an error is causing problems to drivers when
hardware is such it works out just fine with no regulator control.
Returning an error forces drivers to specifically handle the case where
CONFIG_REGULATOR is not set, making the mere existence of the stub
questionalble.
Change the stub implementation for the
devm_regulator_get_enable_optional() to return Ok so drivers do not
separately handle the case where the CONFIG_REGULATOR is not set.

The MT6360 regulator binding, the example in the MT6360 mfd binding, and
the devicetree users of those bindings are rightfully declaring MT6360
regulator subnodes with non-capital names, and luckily without using the
deprecated regulator-compatible property.
With this driver declaring capitalized BUCKx/LDOx as of_match string for
the node names, obviously no regulator gets probed: fix that by changing
the MT6360_REGULATOR_DESC macro to add a "match" parameter which gets
assigned to the of_match.

The of_match shall correspond to the name of the regulator subnode,
or the deprecated `regulator-compatible` property must be used:
failing to do so, the regulator won't probe (and the driver will
as well not probe).
Since the devicetree binding for this driver is actually correct
and wants DTs to use the "usb-otg-vbus-regulator" subnode name,
fix this driver by aligning the `of_match` string to what the DT
binding wants.

For all the "score" pin-groups all the intel_pingroup-s to select
the non GPIO function are re-used for byt_score_gpio_groups[].
But this is incorrect since a pin-group includes the mode setting,
which for the non GPIO functions generally is 1, where as to select
the GPIO function mode must be set to 0.
So the GPIO function needs separate intel_pingroup-s with their own mode
value of 0.
Add a new PIN_GROUP_GPIO macro which adds a foo_gpio entry to each
pin-group defined this way and update byt_score_gpio_groups[] to point
to the new foo_gpio entries.
The "sus" usb_oc_grp usb_ulpi_grp and pcu_spi_grp pin-groups are special
because these have a non 0 mode value to select the GPIO functions and
these already have matching foo_gpio pin-groups, leave these are unchanged.
The pmu_clk "sus" groups added in commit 2f46d7f7e959 ("pinctrl: baytrail:
Add pinconf group + function for the pmu_clk") do need to use the new
PIN_GROUP_GPIO macro.

There is a misinterpretation of some of the PIN_CONFIG_* options in this
driver library. PIN_CONFIG_OUTPUT_ENABLE should refer to a buffer or
switch in the output direction of the electrical path. The MediaTek
hardware does not have such a thing. The driver incorrectly maps this
option to the GPIO function's direction.
Likewise, PIN_CONFIG_INPUT_ENABLE should refer to a buffer or switch in
the input direction. The hardware does have such a mechanism, and is
mapped to the IES bit. The driver however sets the direction in addition
to the IES bit, which is incorrect. On readback, the IES bit isn't even
considered.
Ironically, the driver does not support readback for PIN_CONFIG_OUTPUT,
while its readback of PIN_CONFIG_{INPUT,OUTPUT}_ENABLE is what it should
be doing for PIN_CONFIG_OUTPUT.
Rework support for these three options, so that PIN_CONFIG_OUTPUT_ENABLE
is completely removed, PIN_CONFIG_INPUT_ENABLE is only linked to the IES
bit, and PIN_CONFIG_OUTPUT is linked to the GPIO function's direction
and output level.

not work well if the channels consume the requests at
different speeds, even if the advertised speeds are the
same.
This change will allow the client to pick the channel
with least number of requests currently in-flight. This
will disregard the link speed, and select a channel
based on the current load of the channels.
For cases when all the channels are equally loaded,
fall back to the old round robin method.

the same file, samples/rust/rust_minimal.d.
This does not happen when compiling C or assembly files because
-Wp,-MMD,$(depfile) explicitly specifies the dependency filepath.
$(depfile) is a unique path for each target.
Currently, rustc is only given --out-dir and --emit=<list-of-types>
So, all the rust build rules output the dep-info into the default
<CRATE_NAME>.d, which causes the path conflict.
Fortunately, the --emit option is able to specify the output path
individually, with the form --emit=<type>=<path>.
Add --emit=dep-info=$(depfile) to the common part. Also, remove the
redundant --out-dir because the output path is specified for each type.
The code gets much cleaner because we do not need to rename *.d files.

There is a recent report on UFFDIO_COPY over hugetlb:
https://lore.kernel.org/all/000000000000ee06de0616177560@google.com/
350: lockdep_assert_held(&hugetlb_lock);
Should be an issue in hugetlb but triggered in an userfault context, where
it goes into the unlikely path where two threads modifying the resv map
together. Mike has a fix in that path for resv uncharge but it looks like
the locking criteria was overlooked: hugetlb_cgroup_uncharge_folio_rsvd()
will update the cgroup pointer, so it requires to be called with the lock
held.

Patch series "convert hugetlb_cgroup helper functions to folios", v2.
This patch series continues the conversion of hugetlb code from being
managed in pages to folios by converting many of the hugetlb_cgroup helper
functions to use folios. This allows the core hugetlb functions to pass
in a folio to these helper functions.
This patch (of 9);
Change __set_hugetlb_cgroup() to use folios so it is explicit that the
function operates on a head page.

Patch series "begin converting hugetlb code to folios", v4.
This patch series starts the conversion of the hugetlb code to operate on
struct folios rather than struct pages. This removes the ambiguitiy of
whether functions are operating on head pages, tail pages of compound
pages, or base pages.
This series passes the linux test project hugetlb test cases.
Patch 1 adds hugeltb specific page macros that can operate on folios.
Patch 2 adds the private field of the first tail page to struct page. For
32-bit, _private_1 alinging with page[1].private was confirmed by using
pahole.
Patch 3 introduces hugetlb subpool helper functions which operate on
struct folios. These patches were tested using the hugepage-mmap.c
selftest along with the migratepages command.
Patch 4 converts hugetlb_delete_from_page_cache() to use folios.
Patch 5 adds a folio_hstate() function to get hstate information from a
folio and adds a user of folio_hstate().
Bpftrace was used to track time spent in the free_huge_pages function
during the ltp test cases as it is a caller of the hugetlb subpool
functions. From the histogram, the performance is similar before and
after the patch series.
Time spent in 'free_huge_page'

The DDR3 SPD data structure advertises the presence of a thermal
sensor on a DDR3 module in byte 32, bit 7. Let's use this information
to explicitly instantiate the thermal sensor I2C client instead of
having to rely on class-based I2C probing.
The temp sensor i2c address can be derived from the SPD i2c address,
so we can directly instantiate the device and don't have to probe
for it. If the temp sensor has been instantiated already by other
means (e.g. class-based auto-detection), then the busy-check in
i2c_new_client_device will detect this.
Note: Thermal sensors on DDR4 DIMM's are instantiated from the
ee1004 driver.

Can now correctly identify where the packets should be delivered by using
md_dst or its absence on devices that provide it.
This detection is not possible without device drivers that update md_dst. A
fallback pattern should be used for supporting such device drivers. This
fallback mode causes multicast messages to be cloned to both the non-macsec
and macsec ports, independent of whether the multicast message received was
encrypted over MACsec or not. Other non-macsec traffic may also fail to be
handled correctly for devices in promiscuous mode.

The power_supply frame-work is not really designed for there to be
long living in kernel references to power_supply devices.
Specifically unregistering a power_supply while some other code has
a reference to it triggers a WARN in power_supply_unregister():
WARN_ON(atomic_dec_return(&psy->use_cnt));
Folllowed by the power_supply still getting removed and the
backing data freed anyway, leaving the tusb1210 charger-detect code
with a dangling reference, resulting in a crash the next time
tusb1210_get_online() is called.
Fix this by only holding the reference in tusb1210_get_online()
freeing it at the end of the function. Note this still leaves
a theoretical race window, but it avoids the issue when manually
