Subject: userfaultfd-non-cooperative-add-event-for-memory-unmaps-fix-2
The prototypes for MMU-based machines and MMU-less builds have to be the
same, this fixes the build errors I saw:
mm/nommu.c:1201:15: error: conflicting types for 'do_mmap'
mm/nommu.c:1580:5: error: conflicting types for 'do_munmap'
Fixes: mmtom ("userfaultfd: non-cooperative: add event for memory unmaps")
