This macro isn't used in Linux, now. Delete in include/linux/sched.h
and arch's include/asm. This would confuse people who are
implementing the COMPAT feature for architecture.

Here is the comment by Arnd:
Looking through the git history, I see commit a06db751c321 ("pagemap:
check permissions and capabilities at open time") removing the last
user.
