[PATCH v2 00/21] Convert all remaining drivers to GEM object functions
The GEM and PRIME related callbacks in struct drm_driver are deprecated in
favor of GEM object functions in struct drm_gem_object_funcs. This patchset
converts the remaining drivers to object functions and removes most of the
obsolete interfaces.
Patches #1 to #16 and #18 to #19 convert DRM drivers to GEM object functions,
one by one. Each patch moves existing callbacks from struct drm_driver to

[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
