I've taken a look into it and got a couple of questions:
- removal of CLONE_VM and CLONE_THREAD from libc/sysdeps/linux/*/clone.S
  probably does not belong to the "nptl: remove asm from sysdep-cancel.h" patch.
- sysdep-cancel.h files now look very similar across all architectures,
  and they no longer seem to be arch-specific. Should they now become a single
  generic file?
