Wire up the new file system mount syscalls for Powerpc. The new syscall being
contemplated by this patch are those already available in the linux-next tree:
open_tree(), move_mount(), fsopen(), fsmount(), fspick() and fsinfo().
These system calls were tested with David Howells test case[1], as some others I
wrote[2]. For testing purpose, I also made usage of the new, but yet not
integrated, fsconfig() syscall.
