====================
sparc64: PCIe performance enhancements
Ver 2 is redone for 4.8 where commit 00085f1efa387a8ce100e3734920f7639c80caa3
changed DMA attributes from struct pointer to unsigned long.
This set of patches initiates a series of PCIe performance enhancement patch
submittals.
Patch 1/2 enables version 2 of the SPARC sun4v IOMMU I/O address translation
services need for subsequent enhancements.
Patch 2/2 allows drivers to specify DMA_ATTR_WEAK_ORDERING via DMA attributes
to the SPARC DMA mapping routines enabling "relaxed ordering" for the buffer
being mapped.
