[PATCH 04/23] agp: Make agp_generic_[alloc|destroy]_pages use the _agp_[alloc|free]_page macro.
From: Konrad Rzeszutek Wilk
Date: Mon Dec 06 2010 - 18:29:25 EST
This way when we want to opt in a platform to use the PCI DMA it
is just the matter of changing the implementation in
arch/<platform>/include/asm/agp.h
