Deltas from patchv5:
- removed iommu_tbl_ops, and instead pass the ->flush_all as
  an indirection to iommu_tbl_pool_init()
- only invoke ->flush_all when there is no large_pool, based on
  the assumption that large-pool usage is infrequently encountered.

Sowmini (2):
  Break up monolithic iommu table/lock into finer graularity pools and
    lock
  Make sparc64 use scalable lib/iommu-common.c functions

Sowmini Varadhan (1):
  Make LDC use common iommu poll management functions
