- A fix for fanotify_mark() missing the conversion of x86_32 native
syscalls which take 64-bit arguments to the compat handlers due to
former having a general compat handler. (Brian Gerst)
- Add a forgotten pmd page destructor call to pud_free_pmd_page() where
a pmd page is freed. (Dan Williams)
- Make IN/OUT insns with an u8 immediate port operand handling for
SEV-ES guests more precise by using only the single port byte and not
the whole s32 value of the insn decoder. (Peter Gonda)
- Correct a straddling end range check before returning the proper MTRR
type, when the end address is the same as top of memory. (Ying-Tsun
Huang)
- Change PQR_ASSOC MSR update scheme when moving a task to a resctrl
resource group to avoid significant performance overhead with some
resctrl workloads. (Fenghua Yu)
- Avoid the actual task move overhead when the task is already in the

Some day I may get used to having to email being sequestered behind both claret and cerulean oath2+sms 2fa layers, but for now I'll stick with keying in one password to receive an email vs. the required four.

io_uring: stop SQPOLL submit on creator's death
When the creator of SQPOLL io_uring dies (i.e. sqo_task), we don't want
its internals like ->files and ->mm to be poked by the SQPOLL task, it
have never been nice and recently got racy. That can happen when the
owner undergoes destruction and SQPOLL tasks tries to submit new
requests in parallel, and so calls io_sq_thread_acquire*().
That patch halts SQPOLL submissions when sqo_task dies by introducing
sqo_dead flag. Once set, the SQPOLL task must not do any submission,
which is synchronised by uring_lock as well as the new flag.
The tricky part is to make sure that disabling always happens, that
means either the ring is discovered by creator's do_exit() -> cancel,
or if the final close() happens before it's done by the creator. The
last is guaranteed by the fact that for SQPOLL the creator task and only
it holds exactly one file note, so either it pins up to do_exit() or
removed by the creator on the final put in flush. (see comments in
uring_flush() around file->f_count == 2).
One more place that can trigger io_sq_thread_acquire_*() is
__io_req_task_submit(). Shoot off requests on sqo_dead there, even
though actually we don't need to. That's because cancellation of
sqo_task should wait for the request before going any further.
note 1: io_disable_sqo_submit() does io_ring_set_wakeup_flag() so the
caller would enter the ring to get an error, but it still doesn't
guarantee that the flag won't be cleared.
note 2: if final __userspace__ close happens not from the creator
task, the file note will pin the ring until the task dies.
Fixed:

bcache: set bcache device into read-only mode for BCH_FEATURE_INCOMPAT_OBSO_LARGE_BUCKET
If BCH_FEATURE_INCOMPAT_OBSO_LARGE_BUCKET is set in incompat feature
set, it means the cache device is created with obsoleted layout with
obso_bucket_site_hi. Now bcache does not support this feature bit, a new
BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE incompat feature bit is added
for a better layout to support large bucket size.
For the legacy compatibility purpose, if a cache device created with
obsoleted BCH_FEATURE_INCOMPAT_OBSO_LARGE_BUCKET feature bit, all bcache
devices attached to this cache set should be set to read-only. Then the
dirty data can be written back to backing device before re-create the
cache device with BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE feature bit
by the latest bcache-tools.
This patch checks BCH_FEATURE_INCOMPAT_OBSO_LARGE_BUCKET feature bit
when running a cache set and attach a bcache device to the cache set. If
this bit is set,
- When run a cache set, print an error kernel message to indicate all
following attached bcache device will be read-only.
- When attach a bcache device, print an error kernel message to indicate
the attached bcache device will be read-only, and ask users to update
to latest bcache-tools.
Such change is only for cache device whose bucket size >= 32MB, this is
for the zoned SSD and almost nobody uses such large bucket size at this
moment. If you don't explicit set a large bucket size for a zoned SSD,
such change is totally transparent to your bcache device.

bcache: introduce BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE for large bucket
When large bucket feature was added, BCH_FEATURE_INCOMPAT_LARGE_BUCKET
was introduced into the incompat feature set. It used bucket_size_hi
(which was added at the tail of struct cache_sb_disk) to extend current
16bit bucket size to 32bit with existing bucket_size in struct
cache_sb_disk.
This is not a good idea, there are two obvious problems,
- Bucket size is always value power of 2, if store log2(bucket size) in
existing bucket_size of struct cache_sb_disk, it is unnecessary to add
bucket_size_hi.
- Macro csum_set() assumes d[SB_JOURNAL_BUCKETS] is the last member in
struct cache_sb_disk, bucket_size_hi was added after d[] which makes
csum_set calculate an unexpected super block checksum.
To fix the above problems, this patch introduces a new incompat feature
bit BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE, when this bit is set, it
means bucket_size in struct cache_sb_disk stores the order of power-of-2
bucket size value. When user specifies a bucket size larger than 32768
sectors, BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE will be set to
incompat feature set, and bucket_size stores log2(bucket size) more
than store the real bucket size value.
The obsoleted BCH_FEATURE_INCOMPAT_LARGE_BUCKET won't be used anymore,
it is renamed to BCH_FEATURE_INCOMPAT_OBSO_LARGE_BUCKET and still only
recognized by kernel driver for legacy compatible purpose. The previous
bucket_size_hi is renmaed to obso_bucket_size_hi in struct cache_sb_disk
and not used in bcache-tools anymore.
For cache device created with BCH_FEATURE_INCOMPAT_LARGE_BUCKET feature,
bcache-tools and kernel driver still recognize the feature string and
display it as "obso_large_bucket".
With this change, the unnecessary extra space extend of bcache on-disk
super block can be avoided, and csum_set() may generate expected check
sum as well.

bcache: check unsupported feature sets for bcache register
This patch adds the check for features which is incompatible for current supported feature sets. Now if the bcache device created by bcache-tools has features that current kernel doesn't support, read_super() will fail with error messoage. E.g. if an unsupported incompatible feature detected, bcache register will fail with dmesg "bcache: register_bcache() error : Unsupported incompatible feature found". Fixes: |

ARM: SoC fixes for v5.11
These are a small number of bug fixes that all came in before or during
the merge window, most for the omap platform:
- One boot regression fix for Nokia N9 (OMAP3).
- Two small defconfig changes for omap2, to reflect changes in drivers
- Warning fixes for DT issues on omap2, picoxcell and bitmap SoCs.
The picoxcell platform will be removed in v5.12, but fixing it
first makes it easier to backport to the fix to stable kernels
and get a clean build with new dtc versions

hwmon: (amd_energy) fix allocation of hwmon_channel_info config
hwmon, specifically hwmon_num_channel_attrs, expects the config
array in the hwmon_channel_info structure to be terminated by
a zero entry. amd_energy does not honor this convention. As
result, a KASAN warning is possible. Fix this by adding an
additional entry and setting it to zero.

blk-mq-debugfs: Add decode for BLK_MQ_F_TAG_HCTX_SHARED
Showing the hctx flags for when BLK_MQ_F_TAG_HCTX_SHARED is set gives
something like:
root@debian:/home/john# more /sys/kernel/debug/block/sda/hctx0/flags
alloc_policy=FIFO SHOULD_MERGE|TAG_QUEUE_SHARED|3
Add the decoding for that flag.

The problem is both code path try to close same session, which lead to
panic.
To fix it, just skip the sess if the refcount already drop to 0.

block/rnbd-clt: Fix sg table use after free
Since dynamically allocate sglist is used for rnbd_iu, we can't free sg
table after send_usr_msg since the callback function (cqe.done) could
still access the sglist.
Otherwise KASAN reports UAF issue:

The solution is to free iu's sgtable after the iu is not used anymore.
And also move sg_alloc_table into rnbd_get_iu accordingly.

The problem is in the sess_dev release function we call
rnbd_destroy_sess_dev, and could free the sess_dev already, but we still
set the keep_id in rnbd_srv_sess_dev_force_close, which lead to use
after free.
To fix it, move the keep_id before the sysfs removal, and cache the
rnbd_srv_session for lock accessing,
