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.
