Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc 

Pull sparc updates from David Miller:
 "Just a couple of fixes/cleanups:

   - Correct NUMA latency calculations on sparc64, from Nitin Gupta.

   - ASI_ST_BLKINIT_MRU_S value was wrong, from Rob Gardner.

   - Fix non-faulting load handling of non-quad values, also from Rob
     Gardner.

   - Cleanup VISsave assembler, from Sam Ravnborg.

   - Fix iommu-common code so it doesn't emit rediculous warnings on
     some architectures, particularly ARM"

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
  sparc64: Fix numa distance values
  sparc64: Don't restrict fp regs for no-fault loads
  iommu-common: Fix error code used in iommu_tbl_range_{alloc,free}().
  sparc64: use ENTRY/ENDPROC in VISsave
  sparc64: Fix incorrect ASI_ST_BLKINIT_MRU_S value
