Andrea Arcangeli 47dd924508 userfaultfd: hugetlbfs: UFFD_FEATURE_MISSING_SHMEM
Userland developers asked to be notified immediately by the UFFDIO_API
ioctl if shmem missing mode is supported by userfaultfd in the running
kernel.  This avoids the need to run UFFDIO_REGISTER on a shmem virtual
memory range to find out.
