Follows up on the feedback in the thread at
http://www.spinics.net/lists/sparclinux/msg13493.html
- removed ->cookie_to_index and ->demap indirection from the iommu_tbl_ops
The caller needs to call these functions as needed, before invoking
the generic arena allocator functions.
- added the "skip_span_boundary" argument to iommu_tbl_pool_init() for
those callers like LDC which do no care about span boundary checks.
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
