drm_gem_cma_prime_import_sg_table() will fail if the number of entries
in the sg_table > 1. However, you can have a device that uses an IOMMU
engine and can map a discontiguous buffer with multiple entries that
have consecutive sg_dma_addresses, effectively making it contiguous.
Allow for that scenario by testing the entries in the sg_table for
contiguous coverage.

The 'struct key_preparsed_payload' will use 'time_t' which we will
try to remove in the kernel, since 'time_t' is not year 2038 safe on
32bits systems.
Thus this patch replaces 'time_t' with 'time64_t' which is year 2038
safe on 32 bits system for 'struct key_preparsed_payload', moreover
we should use the 'TIME64_MAX' macro to initialize the 'time64_t'
type variable.

The 'struct key' will use 'time_t' which we try to remove in the
kernel, since 'time_t' is not year 2038 safe on 32bit systems.
Also the 'struct keyring_search_context' will use 'timespec' type
to record current time, which is also not year 2038 safe on 32bit
systems.
Thus this patch replaces 'time_t' with 'time64_t' which is year 2038
safe for 'struct key', and replace 'timespec' with 'time64_t' for the
'struct keyring_search_context', since we only look at the the seconds
part of 'timespec' variable. Moreover we also change the codes where
using the 'time_t' and 'timespec', and we can get current time by
ktime_get_real_seconds() instead of current_kernel_time(), and use
'TIME64_MAX' macro to initialize the 'time64_t' type variable.
Especially in proc.c file, we have replaced 'unsigned long' and 'timespec'
type with 'u64' and 'time64_t' type to save the timeout value, which means
user will get one 'u64' type timeout value by issuing proc_keys_show()
function.

Apparently some sinks look at the YQ bits even when receiving RGB,
and they get somehow confused when they see a non-zero YQ value.
So we can't just blindly follow CEA-861-F and set YQ to match the
RGB range.
Unfortunately there is no good way to tell whether the sink
designer claims to have read CEA-861-F. The CEA extension block
revision number has generally been stuck at 3 since forever,
and even a very recently manufactured sink might be based on
an old design so the manufacturing date doesn't seem like
something we can use. In lieu of better information let's
follow CEA-861-F only for HDMI 2.0 sinks, since HDMI 2.0 is
based on CEA-861-F. For HDMI 1.x sinks we'll always set YQ=0.
The alternative would of course be to always set YQ=0. And if
we ever encounter a HDMI 2.0+ sink with this bug that's what
we'll probably have to do.

syzbot easily found a regression added in our latest patches [1]
No longer set tp->highest_sack to the head of the send queue since
this is not logical and error prone.
Only sack processing should maintain the pointer to an skb from rtx queue.
We might in the future only remember the sequence instead of a pointer to skb,
since rb-tree should allow a fast lookup.

"There are no big surprising changes in this cycle, yet not too boring,

As new features in ASoC side, there are two things: a new AC97 bus
implementation and AMD Stony platform support. Both include the
relevant changes shared with other subsystems, e.g. AC97 MFD changes
and DRM AMD changes.
Some other highlighted topics are:
- A bunch of USB-audio drivers got the hardening against the
malicious device accesses with a new helper code for endpoint
sanity check
- Lots of cleanups for ASoC Intel platform code, including support
for their open source audio firmware

semantics as before, but also no open draining, and allow the raw
operations to affect lines used for interrupts as the caller
supposedly knows what they are doing if they are getting the big
hammer.
- Rewrote the __inner_function() notation calls to names that make
more sense. I just find this kind of code disturbing.
- Drop the .irq_base() field from the gpiochip since now all IRQs are
mapped dynamically. This is nice.
- Support for .get_multiple() in the core driver API. This allows us
to read several GPIO lines with a single register read. This has
high value for some usecases: it can be used to create
oscilloscopes and signal analyzers and other things that rely on
reading several lines at exactly the same instant. Also a generally
nice optimization. This uses the new assign_bit() macro from the
bitops lib that was ACKed by Andrew Morton and is implemented for
two drivers, one of them being the generic MMIO driver so everyone
using that will be able to benefit from this.
- Do not allow requests of Open Drain and Open Source setting of a
GPIO line simultaneously. If the hardware actually supports
enabling both at the same time the electrical result would be
disastrous.
- A new interrupt chip core helper. This will be helpful to deal with
"banked" GPIOs, which means GPIO controllers with several logical
blocks of GPIO inside them. This is several gpiochips per device in
the device model, in contrast to the case when there is a 1-to-1
relationship between a device and a gpiochip.
New drivers:
- Maxim MAX3191x industrial serializer, a very interesting piece of
professional I/O hardware.
- Uniphier GPIO driver. This is the GPIO block from the recent
Socionext (ex Fujitsu and Panasonic) platform.
- Tegra 186 driver. This is based on the new banked GPIO
infrastructure.
Other improvements:
- Some documentation improvements.
- Wakeup support for the DesignWare DWAPB GPIO controller.
- Reset line support on the DesignWare DWAPB GPIO controller.
- Several non-critical bug fixes and improvements for the Broadcom
BRCMSTB driver.
- Misc non-critical bug fixes like exotic errorpaths, removal of dead
code etc.
- Explicit comments on fall-through switch() statements"

fill_balloon doing memory allocations under balloon_lock
can cause a deadlock when leak_balloon is called from
virtballoon_oom_notify and tries to take same lock.
To fix, split page allocation and enqueue and do allocations outside the lock.
Here's a detailed analysis of the deadlock by Tetsuo Handa:
In leak_balloon(), mutex_lock(&vb->balloon_lock) is called in order to
serialize against fill_balloon(). But in fill_balloon(),
alloc_page(GFP_HIGHUSER[_MOVABLE] | __GFP_NOMEMALLOC | __GFP_NORETRY) is
called with vb->balloon_lock mutex held. Since GFP_HIGHUSER[_MOVABLE]
implies __GFP_DIRECT_RECLAIM | __GFP_IO | __GFP_FS, despite __GFP_NORETRY
is specified, this allocation attempt might indirectly depend on somebody
else's __GFP_DIRECT_RECLAIM memory allocation. And such indirect
__GFP_DIRECT_RECLAIM memory allocation might call leak_balloon() via
virtballoon_oom_notify() via blocking_notifier_call_chain() callback via
out_of_memory() when it reached __alloc_pages_may_oom() and held oom_lock
mutex. Since vb->balloon_lock mutex is already held by fill_balloon(), it
will cause OOM lockup.
Thread1 Thread2
fill_balloon()
takes a balloon_lock
balloon_page_enqueue()
alloc_page(GFP_HIGHUSER_MOVABLE)
direct reclaim (__GFP_FS context) takes a fs lock
waits for that fs lock alloc_page(GFP_NOFS)
__alloc_pages_may_oom()
takes the oom_lock
out_of_memory()
blocking_notifier_call_chain()
leak_balloon()
tries to take that balloon_lock and deadlocks

Pull gfs2 updates from Bob Peterson:
"We've got a total of 17 GFS2 patches for this merge window. The
patches are basically in three categories: (1) patches related to
broken xfstest cases, (2) patches related to improving iomap and start
using it in GFS2, and (3) general typos and clarifications.
Please note that one of the iomap patches extends beyond GFS2 and
affects other file systems, but it was publically reviewed by a
variety of file system people in the community.
From Andreas Gruenbacher:
- rename variable 'bsize' to 'factor' to clarify the logic related to
gfs2_block_map.
- correctly set ctime in the setflags ioctl, which fixes broken
xfstests test 277.
- fix broken xfstest 258, due to an atime initialization problem.
- fix broken xfstest 307, in which GFS2 was not setting ctime when
setting acls.
- switch general iomap code from blkno to disk offset for a variety
of file systems.
- add a new IOMAP_F_DATA_INLINE flag for iomap to indicate blocks
that have data mixed with metadata.
- implement SEEK_HOLE and SEEK_DATA via iomap in GFS2.
- fix failing xfstest case 066, which was due to not properly syncing
dirty inodes when changing extended attributes.
- fix a minor typo in a comment.
- partially fix xfstest 424, which involved GET_FLAGS and SET_FLAGS
ioctl. This is also a cleanup and simplification of the translation
of flags from fs flags to gfs2 flags.
- add support for STATX_ATTR_ in statx, which fixed broken xfstest
424.
- fix for failing xfstest 093 which fixes a recursive glock problem
with gfs2_xattr_get and _set
From me:
- make inode height info part of the 'metapath' data structure to
facilitate using iomap in GFS2.
- start using iomap inside GFS2 and switch GFS2's block_map functions
to use iomap under the covers.
- switch GFS2's fiemap implementation from using block_map to using
iomap under the covers.
- fix journaled data pages not being properly synced to media when
writing inodes. This was caught with xfstests.
- fix another failing xfstest case in which switching a file from
ordered_write to journaled data via set_flags caused a deadlock"

Pull btrfs updates from David Sterba:
"There are some new user features and the usual load of invisible
enhancements or cleanups.
New features:
- extend mount options to specify zlib compression level, -o
compress=zlib:9
- v2 of ioctl "extent to inode mapping", addressing a usecase where
we want to retrieve more but inaccurate results and do the
postprocessing in userspace, aiding defragmentation or
deduplication tools
- populate compression heuristics logic, do data sampling and try to
guess compressibility by: looking for repeated patterns, counting
unique byte values and distribution, calculating Shannon entropy;
this will need more benchmarking and possibly fine tuning, but the
base should be good enough
- enable indexing for btrfs as lower filesystem in overlayfs
- speedup page cache readahead during send on large files
Internal enhancements:
- more sanity checks of b-tree items when reading them from disk
- more EINVAL/EUCLEAN fixups, missing BLK_STS_* conversion, other
errno or error handling fixes
- remove some homegrown IO-related logic, that's been obsoleted by
core block layer changes (batching, plug/unplug, own counters)
- add ref-verify, optional debugging feature to verify extent
reference accounting
- simplify code handling outstanding extents, make it more clear
where and how the accounting is done
- make delalloc reservations per-inode, simplify the code and make
the logic more straightforward
- extensive cleanup of delayed refs code
Notable fixes:
- fix send ioctl on 32bit with 64bit kernel"
