-Subject: drm: Remove PageReserved manipulation from drm_pci_alloc
-
-drm_pci_alloc/drm_pci_free are very thin wrappers around the core dma
-facilities, and we have no special reason within the drm layer to behave
-differently. In particular, since

-    page-flags: define PG_reserved behavior on compound pages
-
-    As far as I can see there's no users of PG_reserved on compound pages.

-
-it has been illegal to combine GFP_COMP with SetPageReserved, so lets
-stop doing both and leave the dma layer to its own devices.
