[GIT PULL] io_uring fixes for 6.6-rc5

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

A few fixes for the 6.6 kernel release:

- syzbot report on a crash on 32-bit arm with highmem, and went digging
  to check for potentially similar issues and found one more (me)

- Fix a syzbot report with PROVE_LOCKING=y and setting up the ring in a
  disabled state (me)

- Fix for race with CPU hotplut and io-wq init (Jeff)

Please pull!
