mm/shmem: introduce shmem_file_setup_with_mnt
We are planning to use our own tmpfs mnt in i915 in place of the shm_mnt, such that we can control the mount options, in particular huge=, which we require to support huge-gtt-pages. So rather than roll our own version of __shmem_file_setup, it would be preferred if we could just give shmem our mnt, and let it do the rest.
