Add omap_gem_unpin_locked() which is a version of omap_gem_unpin() that
expects the caller to hold the omap_obj lock.

Add an optional CRTC gamma LUT support, and enable it on RK3288.
This is currently enabled via a separate address resource,
which needs to be specified in the devicetree.
The address resource is required because on some SoCs, such as
RK3288, the LUT address is after the MMU address, and the latter
is supported by a different driver. This prevents the DRM driver
from requesting an entire register space.
The current implementation works for RGB 10-bit tables, as that
is what seems to work on RK3288.

Depending on inlining decisions by the compiler, __get/put_user_fn
might become out of line. Then the compiler is no longer able to tell
that size can only be 1,2,4 or 8 due to the check in __get/put_user
resulting in false positives like
./arch/s390/include/asm/uaccess.h: In function ‘__put_user_fn’:
./arch/s390/include/asm/uaccess.h:113:9: warning: ‘rc’ may be used uninitialized in this function [-Wmaybe-uninitialized]

Commit 4b708b7b1a2c ("firmware: google: check if size is valid when
decoding VPD data") adds length checks, but the new vpd_decode_entry()
function botched the logic -- it adds the key length twice, instead of
adding the key and value lengths separately.
On my local system, this means vpd.c's vpd_section_create_attribs() hits
an error case after the first attribute it parses, since it's no longer
looking at the correct offset. With this patch, I'm back to seeing all
the correct attributes in /sys/firmware/vpd/...

We have two ways a request can be deferred:
1) It's a regular request that depends on another one
2) It's a timeout that tracks completions
We have a shared helper to determine whether to defer, and that
attempts to make the right decision based on the request. But we
only have some of this information in the caller. Un-share the
two timeout/defer helpers so the caller can use the right one.

smc_rx_recvmsg() first checks if data is available, and then if
RCV_SHUTDOWN is set. There is a race when smc_cdc_msg_recv_action() runs
in between these 2 checks, receives data and sets RCV_SHUTDOWN.
In that case smc_rx_recvmsg() would return from receive without to
process the available data.
Fix that with a final check for data available if RCV_SHUTDOWN is set.
Move the check for data into a function and call it twice.
And use the existing helper smc_rx_data_available().

smc_cdc_rxed_any_close_or_senddone() is used as an end condition for the
receive loop. This conflicts with smc_cdc_msg_recv_action() which could
run in parallel and set the bits checked by
smc_cdc_rxed_any_close_or_senddone() before the receive is processed.
In that case we could return from receive with no data, although data is
available. The same applies to smc_rx_wait().
Fix this by checking for RCV_SHUTDOWN only, which is set in
smc_cdc_msg_recv_action() after the receive was actually processed.

Mariusz reported that invalid packets are sent after resume from
suspend if jumbo packets are active. It turned out that his BIOS
resets chip settings to non-jumbo on resume. Most chip settings are
re-initialized on resume from suspend by calling rtl_hw_start(),
so let's add configuring jumbo to this function.
There's nothing wrong with the commit marked as fixed, it's just
the first one where the patch applies cleanly.

Since commit 4f8943f80883 ("SUNRPC: Replace direct task wakeups from
softirq context") there has been a race to the value of the sk_err if both
XPRT_SOCK_WAKE_ERROR and XPRT_SOCK_WAKE_DISCONNECT are set. In that case,
we may end up losing the sk_err value that existed when xs_error_report was
called.
Fix this by reverting to the previous behavior: instead of using SO_ERROR
to retrieve the value at a later time (which might also return sk_err_soft),
copy the sk_err value onto struct sock_xprt, and use that value to wake
pending tasks.

In prep for newer platforms having more complicated ways to determine
the SAGV block time, move the variable to dev_priv, and extract the
setting to an initial setup function. While we're at it, update the if
ladder to follow the new gen -> old gen order preference, and warn on
any non-specified gen.
v2: Shorten the function name (Ville), return directly (Ville), move
sagv_block_time_us value to dev_priv (Ville)
v3: Change sagv_block_time_us to u32 (Lucas), Change fallback value to
-1 (Lucas), use intel_has_sagv for setup check rather than hand-rolling
(Lucas)

Now that we have the engine stored in i915_perf, we have a means of
accessing intel_gt should we require it. However, we are currently only
using the intel_gt to find the right intel_uncore, so replace our
i915_perf.gt pointer with the more useful i915_perf.uncore.

1. nbd_put takes the mutex and drops nbd->ref to 0. It then does
idr_remove and drops the mutex.
2. nbd_genl_connect takes the mutex. idr_find/idr_for_each fails
to find an existing device, so it does nbd_dev_add.
3. just before the nbd_put could call nbd_dev_remove or not finished
totally, but if nbd_dev_add try to add_disk, we can hit:
debugfs: Directory 'nbd1' with parent 'block' already present!
This patch will make sure all the disk add/remove stuff are done
by holding the nbd_index_mutex lock.

As the removed comments say, these aren't DT based devices.
of_dma_configure() is going to stop allowing a NULL DT node and calling
it will no longer work.
The comment is also now out of date as of commit 9ab91e7c5c51 ("arm64:
default to the direct mapping in get_arch_dma_ops"). Direct mapping
is now the default rather than dma_dummy_ops.
According to Stefano and Oleksandr, the only other part needed is
setting the DMA masks and there's no reason to restrict the masks to
32-bits. So set the masks to 64 bits.

We have a src and dect rectangle, use it instead of relying on
the core drm properties.
Because the core by default clips the src/dst properties, after
the drm_atomic_helper_check_plane_state() we manually set the
unclipped src/dst rectangles. We still need the call for
visibility checks, but this way we are able to use the src/dst
rects in the check/commit code.
This removes the special case in the watermark code for cursor w/h.

Pull in all the changes done during fastset as well. It makes no sense

Commit 721b1d98fb517a ("dm snapshot: Fix excessive memory usage and
workqueue stalls") introduced a semaphore to limit the maximum number of
in-flight kcopyd (COW) jobs.
The implementation of this throttling mechanism is prone to a deadlock:
1. One or more threads write to the origin device causing COW, which is
performed by kcopyd.
2. At some point some of these threads might reach the s->cow_count
semaphore limit and block in down(&s->cow_count), holding a read lock
on _origins_lock.
3. Someone tries to acquire a write lock on _origins_lock, e.g.,
snapshot_ctr(), which blocks because the threads at step (2) already
hold a read lock on it.
4. A COW operation completes and kcopyd runs dm-snapshot's completion
callback, which ends up calling pending_complete().
pending_complete() tries to resubmit any deferred origin bios. This
requires acquiring a read lock on _origins_lock, which blocks.
This happens because the read-write semaphore implementation gives
priority to writers, meaning that as soon as a writer tries to enter
the critical section, no readers will be allowed in, until all
writers have completed their work.
So, pending_complete() waits for the writer at step (3) to acquire
and release the lock. This writer waits for the readers at step (2)
to release the read lock and those readers wait for
pending_complete() (the kcopyd thread) to signal the s->cow_count
semaphore: DEADLOCK.
The above was thoroughly analyzed and documented by Nikos Tsironis as
part of his initial proposal for fixing this deadlock, see:
https://www.redhat.com/archives/dm-devel/2019-October/msg00001.html
Fix this deadlock by reworking COW throttling so that it waits without
holding any locks. Add a variable 'in_progress' that counts how many
kcopyd jobs are running. A function wait_for_in_progress() will sleep if
'in_progress' is over the limit. It drops _origins_lock in order to
avoid the deadlock.
