Subject talks about "*_pages"
Can you elaborate why the move from mm.h to memremap.h is justified?
Patch 2 adds is_device_coherent_page in memremap.h and updates
is_longterm_pinnable_page to call is_device_coherent_page. memremap.h
cannot include mm.h because it is itself included by mm.h. So the choice
was to move is_longterm_pinnable_page to memremap.h, or move
is_device_coherent_page and all its dependencies to mm.h. The latter
would have been a bigger change.
I'd have called it "is_longterm_pinnable_page", but I am not a native
speaker, so no strong opinion :)
I think only the patch title has the name backwards. The code uses
is_longterm_pinnable_page.
