Remove __ASSUME_GETCPU_SYSCALL
Commit Message
This patch removes the definition of __ASSUME_GETCPU_SYSCALL. In fact
this macro is unused, probably since:
commit dd26c44403582fdf10d663170f947dfe4b3207a0

Consolidate sched_getcpu
so it could have been removed even without the move to 3.2 as minimum
kernel version on x86_64.
Tested for x86_64.
