powerpc/pkeys: Remove unused code
This removes arch_supports_pkeys(), arch_usable_pkeys() and thread_pkey_regs_*() which are remnants from the following: commit06bb53b338
("powerpc: store and restore the pkey state across context switches") commit2cd4bd192e
("powerpc/pkeys: Fix handling of pkey state across fork()") commitcf43d3b264
("powerpc: Enable pkey subsystem") arch_supports_pkeys() and arch_usable_pkeys() were unused since their introduction while thread_pkey_regs_*() became unused after the introduction of the following: commitd5fa30e699
("powerpc/book3s64/pkeys: Reset userspace AMR correctly on exec") commit48a8ab4eeb
("powerpc/book3s64/pkeys: Don't update SPRN_AMR when in kernel mode") Signed-off-by: Sandipan Das <sandipan@linux.ibm.com> Reviewed-by: Ram Pai <linuxram@us.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20210202150050.75335-1-sandipan@linux.ibm.com
