Merge drm/drm-next into drm-intel-next

Sync drm-intel-next with v6.0-rc as well as recent drm-intel-gt-next.

Since drm-next does not have commit f0c70d41e4e8 ("drm/i915/guc: remove
runtime info printing from time stamp logging") yet, only
drm-intel-gt-next, will need to do that as part of the merge here to
build.

Merge tag 'for-5.20/io_uring-2022-07-29' of git://git.kernel.dk/linux-block

Pull io_uring updates from Jens Axboe:

- As per (valid) complaint in the last merge window, fs/io_uring.c has
grown quite large these days. io_uring isn't really tied to fs
either, as it supports a wide variety of functionality outside of
that.

Move the code to io_uring/ and split it into files that either
implement a specific request type, and split some code into helpers
as well. The code is organized a lot better like this, and io_uring.c
is now < 4K LOC (me).

- Deprecate the epoll_ctl opcode. It'll still work, just trigger a
warning once if used. If we don't get any complaints on this, and I
don't expect any, then we can fully remove it in a future release
(me).

- Improve the cancel hash locking (Hao)

- kbuf cleanups (Hao)

- Efficiency improvements to the task_work handling (Dylan, Pavel)

- Provided buffer improvements (Dylan)

- Add support for recv/recvmsg multishot support. This is similar to
the accept (or poll) support for have for multishot, where a single
SQE can trigger everytime data is received. For applications that
expect to do more than a few receives on an instantiated socket, this
greatly improves efficiency (Dylan).

- Efficiency improvements for poll handling (Pavel)

- Poll cancelation improvements (Pavel)

- Allow specifiying a range for direct descriptor allocations (Pavel)

- Cleanup the cqe32 handling (Pavel)

- Move io_uring types to greatly cleanup the tracing (Pavel)

- Tons of great code cleanups and improvements (Pavel)

- Add a way to do sync cancelations rather than through the sqe -> cqe
interface, as that's a lot easier to use for some use cases (me).

- Add support to IORING_OP_MSG_RING for sending direct descriptors to a
different ring. This avoids the usually problematic SCM case, as we
disallow those. (me)

- Make the per-command alloc cache we use for apoll generic, place
limits on it, and use it for netmsg as well (me).

- Various cleanups (me, Michal, Gustavo, Uros)
