Merge v6.2-rc6 into drm-next

Due to holidays we started -next with more -fixes in-flight than
usual, and people have been asking where they are. Backmerge to get
things better in sync.

Conflicts:
- Tiny conflict in drm_fbdev_generic.c between variable rename and
missing error handling that got added.
- Conflict in drm_fb_helper.c between the added call to vgaswitcheroo
in drm_fb_helper_single_fb_probe and a refactor patch that extracted
lots of helpers and incidentally removed the dev local variable.
Readd it to make things compile.

io_uring/msg-ring: ensure flags passing works for task_work completions

If the target ring is using IORING_SETUP_SINGLE_ISSUER and we're posting
a message from a different thread, then we need to ensure that the
fallback task_work that posts the CQE knwos about the flags passing as
well. If not we'll always be posting 0 as the flags.

io_uring/msg_ring: Pass custom flags to the cqe

This patch adds a new flag (IORING_MSG_RING_FLAGS_PASS) in the message
ring operations (IORING_OP_MSG_RING). This new flag enables the sender
to specify custom flags, which will be copied over to cqe->flags in the
receiving ring. These custom flags should be specified using the
sqe->file_index field.

This mechanism provides additional flexibility when sending messages
between rings.

"Fixes for the MSG_RING opcode. Nothing really major:

- Fix an overflow missing serialization around posting CQEs to the
target ring (me)

- Disable MSG_RING on a ring that isn't enabled yet. There's nothing
really wrong with allowing it, but 1) it's somewhat odd as nobody
can receive them yet, and 2) it means that using the right delivery
mechanism might change. As nobody should be sending CQEs to a ring
that isn't enabled yet, let's just disable it (Pavel)

io_uring/msg_ring: fix flagging remote execution

There is a couple of problems with queueing a tw in io_msg_ring_data()
for remote execution. First, once we queue it the target ring can
go away and so setting IORING_SQ_TASKRUN there is not safe. Secondly,
the userspace might not expect IORING_SQ_TASKRUN.

Extract a helper and uniformly use TWA_SIGNAL without TWA_SIGNAL_NO_IPI
tricks for now, just as it was done in the original patch.

io_uring/msg_ring: fix missing lock on overflow for IOPOLL

If the target ring is configured with IOPOLL, then we always need to hold

unconditionally, but since we don't expect many target rings to be of this
type, make grabbing the uring_lock conditional on the ring type.
