Subject[PATCH] powerpc: Wire up file system mount new syscalls
Date
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.
