The issue is that when we split a large ZONE_DEVICE folio to order-0 ones,
we don't reset the order/_nr_pages. As folio->_nr_pages overlays
page[1]->memcg_data, once page[1] is a folio, it suddenly looks like it
has folio->memcg_data set. And we never manually initialize
folio->memcg_data in fsdax code, because we never expect it to be set at
all.
When __lruvec_stat_mod_folio() then stumbles over such a folio, it tries
to use folio->memcg_data (because it's non-NULL) but it does not actually
point at a memcg, resulting in the problem.
Alison also observed that these folios sometimes have "locked" set, which
is rather concerning (folios locked from the beginning ...). The reason
is that the order for large folios is stored in page[1]->flags, which
become the folio->flags of a new small folio.
Let's fix it by adding a folio helper to clear order/_nr_pages for
splitting purposes.
Maybe we should reinitialize other large folio flags / folio members as
well when splitting, because they might similarly cause harm once page[1]
becomes a folio? At least other flags in PAGE_FLAGS_SECOND should not be
set for fsdax, so at least page[1]->flags might be as expected with this
fix.
From a quick glimpse, initializing ->mapping, ->pgmap and ->share should
re-initialize most things from a previous page[1] used by large folios
that fsdax cares about. For example folio->private might not get
reinitialized, but maybe that's not relevant -- no traces of it's use in
fsdax code. Needs a closer look.
Another thing that should be considered in the future is performing
similar checks as we perform in free_tail_page_prepare()
-- checking pincount etc.
-- when freeing a large fsdax folio.

When the last page in the zone is accepted, __accept_page() calls
static_branch_dec(). This function takes cpu_hotplug_lock, which can lead
to a deadlock if the allocation occurs during CPU bringup path as
_cpu_up() also takes the lock.
To prevent this deadlock, defer static_branch_dec() to a workqueue.
Call static_branch_dec() only when the workqueue is not yet initialized.
Workqueues are initialized before CPU bring up, so this will not conflict
with the first scenario.

The filter string testing uses strncpy_from_kernel/user_nofault() to
retrieve the string to test the filter against. The if() statement was
incorrect as it considered 0 as a fault, when it is only negative that it
faulted.
Running the following commands:
# cd /sys/kernel/tracing
# echo "filename.ustring ~ \"/proc*\"" > events/syscalls/sys_enter_openat/filter
# echo 1 > events/syscalls/sys_enter_openat/enable
# ls /proc/$$/maps
# cat trace
Would produce nothing, but with the fix it will produce something like:

The PXP terminate debugfs currently unconditionally simulates a
termination, no matter what the HW status is. This is unneeded if PXP is
not in use and can cause errors if the HW init hasn't completed yet.
To solve these issues, we can simply limit the terminations to the cases
where PXP is fully initialized and in use.

The is_vram() is checking the current placement, however if we consider
exported VRAM with dynamic dma-buf, it looks possible for the xe driver
to async evict the memory, notifying the importer, however importer does
not have to call unmap_attachment() immediately, but rather just as
"soon as possible", like when the dma-resv idles. Following from this we
would then pipeline the move, attaching the fence to the manager, and
then update the current placement. But when the unmap_attachment() runs
at some later point we might see that is_vram() is now false, and take
the complete wrong path when dma-unmapping the sg, leading to
explosions.
To fix this check if the sgl was mapping a struct page.
v2:
- The attachment can be mapped multiple times it seems, so we can't
really rely on encoding something in the attachment->priv. Instead
see if the page_link has an encoded struct page. For vram we expect
this to be NULL.

User is reporting what smells like notifier vs folio deadlock, where
migrate_pages_batch() on core kernel side is holding folio lock(s) and
then interacting with the mappings of it, however those mappings are
tied to some userptr, which means calling into the notifier callback and
grabbing the notifier lock. With perfect timing it looks possible that
the pages we pulled from the hmm fault can get sniped by
migrate_pages_batch() at the same time that we are holding the notifier
lock to mark the pages as accessed/dirty, but at this point we also want
to grab the folio locks(s) to mark them as dirty, but if they are
contended from notifier/migrate_pages_batch side then we deadlock since
folio lock won't be dropped until we drop the notifier lock.
Fortunately the mark_page_accessed/dirty is not really needed in the
first place it seems and should have already been done by hmm fault, so
just remove it.

The metadata saved in the ADS is read by GuC when it's initialized.
Saving the addresses to the LRCs when they are populated is too late as
GuC will keep using the old ones.
This was causing GuC to use the RCS LRC for any engine class. It's not a
big problem on a Linux-only scenario since the they are used by GuC only
on media engines when the watchdog is triggered. However, in a
virtualization scenario with Windows as the VF, it causes the wrong LRCs
to be loaded as the watchdog is used for all engines.
Fix it by letting guc_golden_lrc_init() initialize the metadata, like
other *_init() functions, and later guc_golden_lrc_populate() to copy
the LRCs to the right places. The former is called before the second GuC
load, while the latter is called after LRCs have been recorded.

In preparation for adding a driver for the new HDMIv2 IP, and
before splitting out the common bits from the HDMI driver, change
the mtk_cec driver from being registered from the mtk_hdmi driver
itself to be a module_platform_driver of its own.
Besides being a cleanup, this also allows build flexibility by
allowing to compile the CECv1 driver only when needed (for example,
this is not needed nor used in HDMIv2 configurations).

A few more device specific fixes plus one trivial quirk. There's a
couple of patches for Tegra which avoid some fairly spectacular log spam
if the hardware breaks in ways which were actually seen in production,
plus a fix for the i.MX driver to propagate errors properly when setting
up the hardware. We also have a trivial patch marking the sun4i driver
as being compatible with GPIO chip selects.

ftrace_graph_ent.depth is int, but ftrace_graph_ent_entry.depth is
unsigned long. This confuses trace-cmd on 64-bit big-endian systems and
makes it print a huge amount of spaces. Fix this by using unsigned int,
which has a matching size, instead.

Subvolume roots and the dirents that point to them are special; they
don't obey the normal snapshot versioning rules because they cross
snapshot boundaries.
We don't keep around older versions of subvolume dirents on rename - we
don't need to, because subvolume dirents are only visible in the parent
subvolume, and we wouldn't be able to match up the different dirent and
inode versions due to crossing the snapshot ID boundary.
That means that when we rename a subvolume, that's been snapshotted, the
older version of the subvolume root will become dangling - it won't have
a dirent that points to it.
That's expected, we just need to tell fsck that this is ok.

Android has mounted the v1 cpuset controller using filesystem type
"cpuset" (not "cgroup") since 2015 [1], and depends on the resulting
behavior where the controller name is not added as a prefix for cgroupfs
files. [2]
Later, a problem was discovered where cpu hotplug onlining did not
affect the cpuset/cpus files, which Android carried an out-of-tree patch
to address for a while. An attempt was made to upstream this patch, but
the recommendation was to use the "cpuset_v2_mode" mount option
instead. [3]
An effort was made to do so, but this fails with "cgroup: Unknown
parameter 'cpuset_v2_mode'" because commit e1cba4b85d ("cgroup: Add
mount flag to enable cpuset to use v2 behavior in v1 cgroup") did not
update the special cased cpuset_mount(), and only the cgroup (v1)
filesystem type was updated.
Add parameter parsing to the cpuset filesystem type so that
cpuset_v2_mode works like the cgroup filesystem type:
$ mkdir /dev/cpuset
$ mount -t cpuset -ocpuset_v2_mode none /dev/cpuset
$ mount|grep cpuset
none on /dev/cpuset type cgroup (rw,relatime,cpuset,noprefix,cpuset_v2_mode,release_agent=/sbin/cpuset_release_agent)

The PXP terminate debugfs currently unconditionally simulates a
termination, no matter what the HW status is. This is unneeded if PXP is
not in use and can cause errors if the HW init hasn't completed yet.
To solve these issues, we can simply limit the terminations to the cases

When adding folio_memcg function call in the zram module for
Android16-6.12, the following error occurs during compilation:
ERROR: modpost: "cgroup_mutex" [../soc-repo/zram.ko] undefined!
This error is caused by the indirect call to lockdep_is_held(&cgroup_mutex)
within folio_memcg. The export setting for cgroup_mutex is controlled by
the CONFIG_PROVE_RCU macro. If CONFIG_LOCKDEP is enabled while
CONFIG_PROVE_RCU is not, this compilation error will occur.
To resolve this issue, add a parallel macro CONFIG_LOCKDEP control to
ensure cgroup_mutex is properly exported when needed.

cpufreq/amd-pstate: Enable ITMT support after initializing core rankings
cpufreq/amd-pstate: Fix min_limit perf and freq updation for performance governor
Since cpufreq_driver_resolve_freq() can run in parallel with
cpufreq_set_policy() and there is no synchronization between them,
the former may access policy->min and policy->max while the latter
is updating them and it may see intermediate values of them due
to the way the update is carried out. Also the compiler is free
to apply any optimizations it wants both to the stores in
cpufreq_set_policy() and to the loads in cpufreq_driver_resolve_freq()
which may result in additional inconsistencies.
To address this, use WRITE_ONCE() when updating policy->min and
policy->max in cpufreq_set_policy() and use READ_ONCE() for reading
them in cpufreq_driver_resolve_freq(). Moreover, rearrange the update
in cpufreq_set_policy() to avoid storing intermediate values in
policy->min and policy->max with the help of the observation that
their new values are expected to be properly ordered upfront.
Also modify cpufreq_driver_resolve_freq() to take the possible reverse
ordering of policy->min and policy->max, which may happen depending on
the ordering of operations when this function and cpufreq_set_policy()
run concurrently, into account by always honoring the max when it
turns out to be less than the min (in case it comes from thermal
throttling or similar).

Notice that ignore_dl_rate_limit() need not piggy back on the
limits_changed handling to achieve its goal (which is to enforce a
frequency update before its due time).
Namely, if sugov_should_update_freq() is updated to check
sg_policy->need_freq_update and return 'true' if it is set when
sg_policy->limits_changed is not set, ignore_dl_rate_limit() may
set the former directly instead of setting the latter, so it can
avoid hitting the memory barrier in sugov_should_update_freq().
Update the code accordingly.

The handling of the limits_changed flag in struct sugov_policy needs to
be explicitly synchronized to ensure that cpufreq policy limits updates
will not be missed in some cases.
Without that synchronization it is theoretically possible that
the limits_changed update in sugov_should_update_freq() will be
reordered with respect to the reads of the policy limits in
cpufreq_driver_resolve_freq() and in that case, if the limits_changed
update in sugov_limits() clobbers the one in sugov_should_update_freq(),
the new policy limits may not take effect for a long time.
Likewise, the limits_changed update in sugov_limits() may theoretically
get reordered with respect to the updates of the policy limits in
cpufreq_set_policy() and if sugov_should_update_freq() runs between
them, the policy limits change may be missed.
To ensure that the above situations will not take place, add memory
barriers preventing the reordering in question from taking place and
add READ_ONCE() and WRITE_ONCE() annotations around all of the
limits_changed flag updates to prevent the compiler from messing up
with that code.

Commit 8e461a1cb4 ("cpufreq: schedutil: Fix superfluous updates caused
by need_freq_update") modified sugov_should_update_freq() to set the
need_freq_update flag only for drivers with CPUFREQ_NEED_UPDATE_LIMITS
set, but that flag generally needs to be set when the policy limits
change because the driver callback may need to be invoked for the new
limits to take effect.
However, if the return value of cpufreq_driver_resolve_freq() after
applying the new limits is still equal to the previously selected
frequency, the driver callback needs to be invoked only in the case
when CPUFREQ_NEED_UPDATE_LIMITS is set (which means that the driver
specifically wants its callback to be invoked every time the policy
limits change).
Update the code accordingly to avoid missing policy limits changes for
drivers without CPUFREQ_NEED_UPDATE_LIMITS.

Add a DT binding for the Visionox G2647FB105, a 6.47 inch 1080x2340
MIPI-DSI CMD mode AMOLED panel used in:

- Xiaomi Mi Note 10 Lite (sm7150-xiaomi-toco)
Xiaomi likes to use different panels in various revisions of the same
device. A factory panel even can be replaced with another model in a
service center.
So, the power configuration of this panel is similar to
some Samsung AMOLED panels, e.g. samsung,ams639rq08, which can be found on
other sm7150 Xiaomi devices. Even though Samsung panels weren't used
in sm7150-xiaomi-tucana and toco, the described voltage rails exist
