char/agp: introduce asm-generic/agp.h
There are several architectures that duplicate definitions of map_page_into_agp(), unmap_page_from_agp() and flush_agp_cache(). Define those in asm-generic/agp.h and use it instead of duplicated per-architecture headers. Signed-off-by: Mike Rapoport (IBM) <rppt@kernel.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
