[RFC v3 00/45] dma-mapping: Use unsigned long for dma_attrs
Hi,
This is third approach (complete this time) for replacing struct
dma_attrs with unsigned long.
The main patch (2/45) doing the change is split into many subpatches
for easier review (3-43). They should be squashed together when
applying.
*Important:* Patchset is *only* build tested on allyesconfigs: ARM,
ARM64, i386, x86_64 and powerpc. Please provide reviewes and tests
for other

[PATCH 0 of 9] swiotlb: use phys_addr_t for pages
Hi all,
Here''s a work in progress series whcih does a partial revert of the
previous swiotlb changes, and does a partial replacement with Becky
Bruce''s series.
The most important difference is Becky''s use of phys_addr_t rather
than page+offset to represent arbitrary pages. This turns out to be
simpler.
I didn''t replicate the map_single_page changes, since
