[RESEND v4 0/3] mm/pkey: Add PKEY_UNRESTRICTED macro

[Yury Khrustalev]

Add PKEY_UNRESTRICTED macro to mman.h and use it in selftests.

For context, this change will also allow for more consistent update of the
Glibc manual which in turn will help with introducing memory protection
keys on AArch64 targets.

Applies to fac04efc5c79 (tag: v6.13-rc2).

Note that I couldn't build ppc tests so I would appreciate if someone
could check the 3rd patch. Thank you!
