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

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

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.

Hi,
While reviewing kvx-mmu.rst I've spotted several places where the
documentation does not match the code, please make sure that the
documentation in this patch actually reflects what the code is doing.
Also, sectioning looked a bit strange to me, make sure to take a look at
