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

Thanks Peter - for the series:
Reviewed-and-tested-by: Jens Axboe <[email protected]>
on arm64 and x86-64. Caveat - only tested the existing futex api, not
the new syscall, and the io_uring futex implementation on top as well.
