Subject: [PATCH] x86, pkeys: remove cruft from never-merged syscalls
pkey_set() and pkey_get() were syscalls present in older versions
of the protection keys patches. The syscall number definitions
were inadvertently left in place. This patch removes them.
I did a git grep and verified that these are the last places in
the tree that these appear, save for the protection_keys.c tests
and Documentation. Those spots talk about functions called
pkey_get/set() which are wrappers for the direct PKRU
instructions, not the syscalls.
