Stefan Hajnoczi fd1a1dc6f5 virtiofs: implement FUSE_INIT map_alignment field ... The device communicates FUSE_SETUPMAPPING/FUSE_REMOVMAPPING alignment constraints via the FUST_INIT map_alignment field. Parse this field and ensure our DAX mappings meet the alignment constraints. We don't actually align anything differently since our mappings are already 2MB aligned. Just check the value when the connection is established. If it becomes necessary to honor arbitrary alignments in the future we'll have to adjust how mappings are sized. The upshot of this commit is that we can be confident that mappings will work even when emulating x86 on Power and similar combinations where the host page sizes are different.
