Hi!

New version of the futex2 patches. Futex2 is a new interface to the same 'old'
futex core. An attempt to get away from the multiplex syscall and add a little
room for extentions.

Changes since v1:
 - Moved the FUTEX2_{8,16,32,64} into FUTEX2_SIZE_Un namespace (tglx)
 - Added FUTEX2_SIZE_MASK by popular demand (arnd,tglx)
 - Added more comments (tglx)
 - Updated __NR_compat_syscalls for arm64 (arnd)
 - Folded some tags
