  • Add hooks to allow a paravirt implementation to track the lifetime of
    an mm. Paravirtualization requires three hooks, but only two are
    needed in common code. They are:

    arch_dup_mmap, which is called when a new mmap is created at fork

    arch_exit_mmap, which is called when the last process reference to an
    mm is dropped, which typically happens on exit and exec.

    The third hook is activate_mm, which is called from the arch-specific
    activate_mm() macro/function, and so doesn't need stub versions for
    other architectures. It's called when an mm is first used.
