Hello.

Just merged the two dicussed patches and fixed an overlooked warning.

v2
- insert a patch refactoring validate_prctl_map
- move find_vma out of the arg_lock critical section

v3
- squash get_cmdline and prctl_set_mm patches (to keep locking
  consistency)
- validate_prctl_map_addr: remove unused variable mm

Michal Koutný (2):
  prctl_set_mm: Refactor checks from validate_prctl_map
  prctl_set_mm: downgrade mmap_sem to read lock
