This document is used by multiple architectures:

Indeed it is...

    $ echo $(git grep -l  pkey_mprotect arch|cut -d'/' -f 2|sort|uniq)
    alpha arm arm64 ia64 m68k microblaze mips parisc powerpc s390 sh sparc x86 xtensa

... but not because we now have a unified space for new syscall numbers ;-)

$ git grep -w ARCH_HAS_PKEYS -- "*Kconf*" arch/powerpc/Kconfig: select ARCH_HAS_PKEYS arch/x86/Kconfig: select ARCH_HAS_PKEYS mm/Kconfig:config ARCH_HAS_PKEYS

I.e. limited to x86 and powerpc.
