Convert the ramfs, shmem, tmpfs, devtmpfs and rootfs filesystems to the new internal mount API as the old one will be obsoleted and removed. This allows greater flexibility in communication of mount parameters between userspace, the VFS and the filesystem. See Documentation/filesystems/mount_api.txt for more information. Note that tmpfs is slightly tricky as it can contain embedded commas, so it can't be trivially split up using strsep() to break on commas in generic_parse_monolithic(). Instead, tmpfs has to supply its own generic parser. However, if tmpfs changes, then devtmpfs and rootfs, which are wrappers around tmpfs or ramfs, must change too - and thus so must ramfs, so these had to be converted also.
