[PATCH] tmpfs: Don't use 64-bit inodes by defulat with 32-bit ino_t

Currently there seems to be an assumption in tmpfs that 64-bit architectures also have a 64-bit ino_t. This is not true; s390 at least has a 32-bit ino_t. With CONFIG_TMPFS_INODE64=y tmpfs mounts will get 64-bit inode numbers and display "inode64" in the mount options, but passing the "inode64"
