Description: nfs4_getfacl decoding kernel oops

Notes:
 bwh: The upstream fix relies on the rather larger commit 6650239a4b01
 'NFS: Don't use vm_map_ram() in readdir'.  If we can get a test case then
 it may be feasible to implement graceful failure instead.  Otherwise this
 is probably unfixable.
