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.

There is a copy of alloc_gatt_pages() and free_gatt_pages in several

the same: alias alloc_gatt_pages() to __get_free_pages(GFP_KERNEL) and

Hi,
asm/agp.h is duplicated in several architectures, with x86 being the
only instance that differs from the rest.
Introduce asm-generic/agp.h and use it instead of per-architecture

I believe that asm-generic is the best tree

I'd suggest to make it vm_flags_init() etc.

Every architecture that supports FLATMEM memory model defines its own
version of pfn_valid() that essentially compares a pfn to max_mapnr.
Use mips/powerpc version implemented as static inline as a generic
implementation of pfn_valid() and drop its per-ar
From: "Mike Rapoport (IBM)"
There is stale definition of pfn_valid() for DISCONTINGMEM memory model
guarded !FLATMEM && !SPARSEMEM && NUMA ifdefery.
Remove everything but definition of pfn_valid() for FLATMEM.

The MMU variant uses generic definitions of page_to_pfn() and
pfn_to_page(), but !MMU defines them in include/asm/page_no.h for no
good reason.
Include asm-generic/memory_model.h in the common include/asm/page.h and
drop redundant definitions.
