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

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

Patches:

 * Patches 1-6 and 8-9 are rather trivial optional tweaks and fixes
   that don't make substantive changes.  I can live with some of these
   being dropped.

 * Patch 7 (removal of the MPX prctls) could use an Ack, but should be
   uncontroversial.

 * Patches 10-11 cover recent extensions to the speculation control
   prctls.

 * Patch 12 adds one particular case Errors for EINVAL, applicable to
   all arch-specific prctls.  I've not tried too hard to be 100%
   comprehensive with the error conditions, since the list in its
   current form looks in need of a major overhaul.

 * Patches 13-14 add the new arm64-specific prctls.
   (PR_SET_TAGGED_ADDR_CTRL requires a bit more discussion and will be
   posted separately.)

Maintainer notes:

 * I'm *asssuming* that the datestamps in .TH are automatically
   updated by maintainer scripts, since maintaining them by hand would
   interact very badly with rebase.  If needed I can go update them by
   hand though.

 * Similarly, in the days of git (and because I see no recent entries)
   I'm assuming that in-file changelogs no longer need to be updated.
   Again, I'm happy to do that if needed.
