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

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

Hi folks, After some time away from it, and a big rebase as a consequence, here is the updated version of paravirt_ops for x86_64, heading to inclusion. Your criticism is of course, very welcome.
