Stanislav Kinsburskii 9365813cad selftests/mm: add HMM test for mmap lock-dropping faults ...

Add test_hmm coverage for the HMM lock-dropping fault path.  The test
module gets a new HMM_DMIRROR_READ_UNLOCKED ioctl that calls
hmm_range_fault_unlocked_timeout() with a timeout of 0, exercising the
unbounded retry mode while allowing the mmap lock to be dropped during
fault handling.

Add a userfaultfd_read selftest that registers an anonymous mapping with
UFFDIO_REGISTER_MODE_MISSING, services the faults from a handler thread
with UFFDIO_COPY, and verifies that HMM can read back the data supplied by
the handler.  This exercises the path where handle_mm_fault() drops
mmap_lock and hmm_range_fault_unlocked_timeout() restarts the walk
internally.
