Subject: [PATCH 2/8] drm/ttm: move ttm_set_memory.h out of include
This is not something drivers should use.
It's not?
Those are helper functions which are used by the two different page
pools to change the global mapping of pages on x86.
I am not really sure what you are doing here.
Making sure that no driver things that it should touch the CPU caching
attributes manually :)
Got it. So should you move the header to the drivers/gpu/drm/ttm ?
Yes, in the long term we probably want to move the functionality into
the DMA API. But for now the TTM subfolder should do as well.
