Pull sparc update from David Miller:
 "Two changes:

  1) It makes no sense to execute a VTOC partition table request in the
     Sun virtual block device driver and fail to load if it doesn't
     succeed because a) we don't use the result at all and b) it won't
     succeed if there is an EFI partition on the disk, for example.

     We read the partition table via the normal means in the block layer
     anyways, so this is really completely useless, so just remove it.

     From Dwight Engen.

  2) Hook up new bpf system call"

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
  sunvdc: don't call VD_OP_GET_VTOC
  sparc: Hook up bpf system call.
