Hi Linus,

Nothing really major in here, and finally nothing really related to
signals. A few minor fixups related to the threading changes, and some
general fixes, that's it.

There's the pending gdb-get-confused-about-arch, but that's more of a
cosmetic issue, nothing that hinder use of it. And given that other
archs will likely be affected by that oddity too, better to postpone any
changes there until 5.13 imho.

This pull request contains:

- Combine signal checking for SQPOLL with parking, as we need to have
  the sqd lock dropped for both cases.

- S_ISBLK read/writes are bounded work, they were mistakenly bundled as
  unbounded.

- Move IO reissue for reg/blk into the read/write part itself, making it
  just be like -EAGAIN retries.

- Cancelation tightening

- Fix for a silly issue introduced with a prior fix this merge window,
  where a failed ring setup could lead to a crash.

- Ensure that we don't overflow ->comm with 10 billion PIDs

- Fix for an iov_iter revert issue earlier in this release.

Please pull!
