Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs 

Pull vfs fixes from Al Viro:
 "A bunch of endianness fixes and a couple of nfsd error value fixes.

  Speaking of endianness stuff, I'm rather tempted to slap

	ccflags-y += -D__CHECK_ENDIAN__

  in fs/Makefile, if not making it default for the entire tree; nfsd
  regressions I've caught make one hell of a pile and we'd obviously
  benefit from having that kind of stuff caught earlier..."
