They all share the same struct io_sync, convert them to use the
io_cmd_type approach instead.

This converts accept, connect, send/recv, sendmsg/recvmsg, shutdown, and
socket to use io_cmd_type.
Signed-off-by: Jens Axboe <axboe@kernel.dk>

There's a special case for recvmsg with MSG_ERRQUEUE set. This is
problematic as it means the core needs to know about this special
request type.

For now, just add a generic flag for it.

Remove struct io_poll_update from io_kiocb, and convert the poll path to

Signed-off-by: Jens Axboe <axboe@kernel.dk>

Remove struct io_poll_iocb from io_kiocb, and convert the poll path to
use the io_cmd_type approach instead.

While at it, rename io_poll_iocb to io_poll which is consistent with the
other request type private structures.

Remove struct io_rw from io_kiocb, and convert the read/write path to
use the io_cmd_type approach instead.
Signed-off-by: Jens Axboe <axboe@kernel.dk>

Each opcode generally has a command structure in io_kiocb which it can
use to store data associated with that request.

In preparation for having the core layer not know about what's inside
these fields, add a generic io_cmd_data type and put in the union as
well.

Define an io_op_def->prep_async() handler and push the async preparation
to there. Since we now have that, we can drop ->needs_async_setup, as
they mean the same thing.
Signed-off-by: Jens Axboe <axboe@kernel.dk>

In preparation for splitting io_uring up a bit, move it into its own
top level directory. It didn't really belong in fs/ anyway, as it's
not a file system only API.

This adds io_uring/ and moves the core files in there, and updates the
MAINTAINERS file for the new location.
Signed-off-by: Jens Axboe <axboe@kernel.dk>

Rather than have two giant switches for doing request preparation and
then for doing request issue, add a prep and issue handler for each
of them in the io_op_defs[] request definition.

 "A couple more retbleed fallout fixes.

  It looks like their urgency is decreasing so it seems like we've
  managed to catch whatever snafus the limited -rc testing has exposed.
  Maybe we're getting ready... :)

   - Make retbleed mitigations 64-bit only (32-bit will need a bit more
     work if even needed, at all).

   - Prevent return thunks patching of the LKDTM modules as it is not
     needed there

   - Avoid writing the SPEC_CTRL MSR on every kernel entry on eIBRS
     parts

   - Enhance error output of apply_returns() when it fails to patch a
     return thunk

   - A sparse fix to the sev-guest module

The mitigations for RETBleed are currently ineffective on x86_32 since
entry_32.S does not use the required macros.  However, for an x86_32
target, the kconfig symbols for them are still enabled by default and
/sys/devices/system/cpu/vulnerabilities/retbleed will wrongly report
that mitigations are in place.

Make all of these symbols depend on X86_64, and only enable RETHUNK by
default on X86_64.
