Hi Dave

A bunch of updates to the prctl(2) man page to fill in missing
prctls (mostly) up to Linux 5.6 (along with a few other tweaks and
fixes).

Patches from the v1 series [1] that have been applied or rejected
already have been dropped.

People not Cc'd on the whole series can find the whole series at
https://lore.kernel.org/linux-man/ .

Patches:

 * Patch 1 is a new (but trivial) formatting fix, unrelated to the new
   prctls.

Applied.

 * Patches 2-3 relate to the speculation control prctls.  These are
   unmodified from v1, but need review.

Applied, and pushed (since there were no review comments from last version).

 * Patches 4-5 relate to the arm64 prctls from v1, with reviewer
   feedback incorporated.  (See notes in the patches.)

I'll hold off on these patches, to see if review comments come in.

 * Patch 6 is *draft* wording for the arm64 address tagging prctls.
   The semantics of address tagging is particularly slippery, so
   this needs discussion before merging.

Okay -- I'll hold off with that patch too.

Cheers,

Michael
