kmemleak reported some memory leak on reading proc files. After adding
some debug lines, find that proc_seq_fops is using seq_release as
release handler, which won't handle the free of 'private' field of
seq_file, while in fact the open handler proc_seq_open could create
the private data with __seq_open_private when state_size is greater
than zero. So after reading files created with proc_create_seq_private,
such as /proc/timer_list and /proc/vmallocinfo, the private mem of a
seq_file is not freed. Fix it by adding the paired proc_seq_release
as the default release handler of proc_seq_ops instead of seq_release.

For now this is purely cosmetic since the (out-of-tree) lima driver for

Then the only solution to restore the communication with the card is an

This adds a new driver for display panels that use the Ilitek ILI9341
controller. It currently supports a single display panel, namely
the YX240QV29-T (e.g. Adafruit 2.4" TFT).
The init sequence is from the Adafruit Python library for the ILI9341
controller. https://github.com/adafruit/Adafruit_Python_ILI9341

Commit 7f0b1bf045 ("arm64: Fix barriers used for page table modifications")
fixed a reported issue with fixmap page-table entries not being visible
to the walker due to a missing DSB instruction. At the same time, it added
ISB instructions to the arm64 set_{pte,pmd,pud} functions, which are not
required by the architecture and make little sense in isolation.
Remove the redundant ISBs.

The implementation of flush_icache_range() includes instruction sequences
which are themselves patched at runtime, so it is not safe to call from
the patching framework.
This patch reworks the alternatives cache-flushing code so that it rolls
its own internal D-cache maintenance using DC CIVAC before invalidating
the entire I-cache after all alternatives have been applied at boot.
Modules don't cause any issues, since flush_icache_range() is safe to
call by the time they are loaded.

A handful of fixes, nothing really concerning and most touching devicetree
files for various platforms.
I also regenerated the shared multiplatform defconfigs; they have drifted
quite a bit due to Kconfig changes and reordering, and several platform
maintainers tried doing the same which resulted in a lot of conflict pain
-- this way we get everybody onto the same base for next merge window.

It may not be the actual real stable mailing list address, but the
stable scripts to actually pick up on the traditional way to mark stable
patches.
There are also reasons to explicitly avoid using the actual mailing list
address, since security patches with embargo dates generally do want the
stable marking, but don't want tools etc to mistakenly send the patch
out to the mailing list early.
So don't warn for things that are still actively used and explicitly
supported.

This patch fixes wrong name of headphone widget for receiving events
of insert/remove headphone plug from simple-card or audio-graph-card.
If we use wrong widget name then we get warning messages such as
"asoc-audio-graph-card sound: ASoC: DAPM unknown pin Headphones"
when the plug is inserted or removed from headphone jack.

Discards issued to a DM thin device can complete to userspace (via
fstrim) _before_ the metadata changes associated with the discards is
reflected in the thinp superblock (e.g. free blocks). As such, if a
user constructs a test that loops repeatedly over these steps, block
allocation can fail due to discards not having completed yet:
1) fill thin device via filesystem file
2) remove file
3) fstrim
From initial report, here:
https://www.redhat.com/archives/dm-devel/2018-April/msg00022.html
"The root cause of this issue is that dm-thin will first remove
mapping and increase corresponding blocks' reference count to prevent
them from being reused before DISCARD bios get processed by the
underlying layers. However. increasing blocks' reference count could
also increase the nr_allocated_this_transaction in struct sm_disk
which makes smd->old_ll.nr_allocated +
smd->nr_allocated_this_transaction bigger than smd->old_ll.nr_blocks.
In this case, alloc_data_block() will never commit metadata to reset
the begin pointer of struct sm_disk, because sm_disk_get_nr_free()
always return an underflow value."
While there is room for improvement to the space-map accounting that
thinp is making use of: the reality is this test is inherently racey and
will result in the previous iteration's fstrim's discard(s) completing
vs concurrent block allocation, via dd, in the next iteration of the
loop.
No amount of space map accounting improvements will be able to allow
user's to use a block before a discard of that block has completed.
So the best we can really do is allow DM thinp to gracefully handle such
aggressive use of all the pool's data by degrading the pool into
out-of-data-space (OODS) mode. We _should_ get that behaviour already
(if space map accounting didn't falsely cause alloc_data_block() to
believe free space was available).. but short of that we handle the
current reality that dm_pool_alloc_data_block() can return -ENOSPC.
