While Kepler does technically support 256x256 cursors, it turns out that
Kepler actually has some additional requirements for scanout surfaces that
we're not enforcing correctly, which aren't present on Maxwell and later.
Cursor surfaces must always use small pages (4K), and overlay surfaces must
always use large pages (128K).
Fixing this correctly though will take a bit more work: as we'll need to
add some code in prepare_fb() to move cursor FBs in large pages to small
pages, and vice-versa for overlay FBs. So until we have the time to do
that, just limit cursor surfaces to 128x128 - a size small enough to always
default to small pages.
This means small ovlys are still broken on Kepler, but it is extremely
unlikely anyone cares about those anyway :).

To optimize some task deferring it until runtime resume unless someone
holds a runtime PM reference (because in this case the task can be done
w/o the overhead of runtime resume), we have to use the runtime PM
get-if-active logic: If the runtime PM usage count is 0 (and so
get-if-in-use would return false) the runtime suspend handler is not
necessarily called yet (it could be just pending), so the device is not
necessarily powered down, and so the runtime resume handler is not
guaranteed to be called.
The fence revocation depends on the above deferral, so add a
get-if-active helper and use it during fence revocation.
v2:
- Add code comment explaining the fence reg programming deferral logic
to i915_vma_revoke_fence(). (Chris)

The enabled_planes bitmask was supposed to track logically enabled
planes (ie. fb!=NULL and crtc!=NULL), but instead we end up putting
even disabled planes into the bitmask since
intel_plane_atomic_check_with_state() only takes the early exit
if the plane was disabled and stays disabled. I think I misread
the early said codepath to exit whenever the plane is logically
disabled, which is not true.
So let's fix this up properly and set the bit only when the plane
actually is logically enabled.

The spec requires to use at least 3.2ms for the AUX timeout period if
there are LT-tunable PHY Repeaters on the link (2.11.2). An upcoming
spec update makes this more specific, by requiring a 3.2ms minimum
timeout period for the LTTPR detection reading the 0xF0000-0xF0007
range (3.6.5.1).
Accordingly disable LTTPR detection until GLK, where the maximum timeout
we can set is only 1.6ms.
Link training in the non-transparent mode is known to fail at least on
some SKL systems with a WD19 dock on the link, which exposes an LTTPR
(see the References below). While this could have different reasons
besides the too short AUX timeout used, not detecting LTTPRs (and so not
using the non-transparent LT mode) fixes link training on these systems.
While at it add a code comment about the platform specific maximum
timeout values.
v2: Add a comment about the g4x maximum timeout as well. (Ville)

- Fix a possible stack corruption and subsequent DLPAR failure in the
rpadlpar_io PCI hotplug driver
- Two build fixes for uncommon configurations
Thanks to Christophe Leroy and Tyrel Datwyler.
* tag 'powerpc-5.12-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux:
PCI: rpadlpar: Fix potential drc_name corruption in store functions
powerpc: Force inlining of cpu_has_feature() to avoid build failure
powerpc/vdso32: Add missing _restgpr_31_x to fix build failure
Without that it's not safe to use them in a linked combination with
others.
Now combinations like IORING_OP_SENDMSG followed by IORING_OP_SPLICE
should be possible.
We already handle short reads and writes for the following opcodes:
- IORING_OP_READV
- IORING_OP_READ_FIXED
- IORING_OP_READ
- IORING_OP_WRITEV
- IORING_OP_WRITE_FIXED
- IORING_OP_WRITE
- IORING_OP_SPLICE
- IORING_OP_TEE
Now we have it for these as well:
- IORING_OP_SENDMSG
- IORING_OP_SEND
- IORING_OP_RECVMSG
- IORING_OP_RECV
For IORING_OP_RECVMSG we also check for the MSG_TRUNC and MSG_CTRUNC
flags in order to call req_set_fail_links().
There might be applications arround depending on the behavior
that even short send[msg]()/recv[msg]() retuns continue an
IOSQE_IO_LINK chain.
It's very unlikely that such applications pass in MSG_WAITALL,
which is only defined in 'man 2 recvmsg', but not in 'man 2 sendmsg'.
It's expected that the low level sock_sendmsg() call just ignores
MSG_WAITALL, as MSG_ZEROCOPY is also ignored without explicitly set
SO_ZEROCOPY.
We also expect the caller to know about the implicit truncation to
MAX_RW_COUNT, which we don't detect.

Mark the current task as running if we need to run task_work from the
io-wq threads as part of work handling. If that is the case, then return
as such so that the caller can appropriately loop back and reset if it
was part of a going-to-sleep flush.

Just like we don't allow normal signals to IO threads, don't deliver a
STOP to a task that has PF_IO_WORKER set. The IO threads don't take
signals in general, and have no means of flushing out a stop either.
Longer term, we may want to look into allowing stop of these threads,
as it relates to eg process freezing. For now, this prevents a spin
issue if a SIGSTOP is delivered to the parent task.

They don't take signals individually, and even if they share signals with
the parent task, don't allow them to be delivered through the worker
thread. Linux does allow this kind of behavior for regular threads, but
it's really a compatability thing that we need not care about for the IO
threads.

This patch adds rename whiteout support in fast commits. Note that the
whiteout object that gets created is actually char device. Which
imples, the function ext4_inode_journal_mode(struct inode *inode)
would return "JOURNAL_DATA" for this inode. This has a consequence in
fast commit code that it will make creation of the whiteout object a
fast-commit ineligible behavior and thus will fall back to full
commits. With this patch, this can be observed by running fast commits
with rename whiteout and seeing the stats generated by ext4_fc_stats
tracepoint as follows:
ext4_fc_stats: dev 254:32 fc ineligible reasons:
XATTR:0, CROSS_RENAME:0, JOURNAL_FLAG_CHANGE:0, NO_MEM:0, SWAP_BOOT:0,
RESIZE:0, RENAME_DIR:0, FALLOC_RANGE:0, INODE_JOURNAL_DATA:16;
num_commits:6, ineligible: 6, numblks: 3
So in short, this patch guarantees that in case of rename whiteout, we
fall back to full commits.
Amir mentioned that instead of creating a new whiteout object for
every rename, we can create a static whiteout object with irrelevant
nlink. That will make fast commits to not fall back to full
commit. But until this happens, this patch will ensure correctness by
falling back to full commits.
