Konstantin Belousov d301b3580f Support for userspace non-transparent superpages (largepages). 
Created with shm_open2(SHM_LARGEPAGE) and then configured with
FIOSSHMLPGCNF ioctl, largepages posix shared memory objects guarantee
that all userspace mappings of it are served by superpage non-managed
mappings.

Only amd64 for now, both 2M and 1G superpages can be requested, the
later requires CPU feature.
