Subject: generic syscalls: kill cruft from removed pkey syscalls
pkey_set() and pkey_get() were syscalls present in older versions of the
protection keys patches. They were fully excised from the x86 code, but
some cruft was left in the generic syscall code. The C++ comments were
intended to help to make it more glaring to me to fix them before actually
submitting them. That technique worked, but later than I would have
liked.
I test-compiled this for arm64.
Fixes: a60f7b69d92c0 ("generic syscalls: Wire up memory protection keys syscalls")
