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
