Hi,
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-architecture definitions
v2:
* fix build on ARM and xtensa
* add Acked- and Reviewed-by, thanks everybody
v1: https://lore.kernel.org/all/20230125190757.22555-1-rppt@xxxxxxxxxx
Mike Rapoport (IBM) (4):
arm: include asm-generic/memory_model.h from page.h rather than
memory.h
m68k: use asm-generic/memory_model.h for both MMU and !MMU
mips: drop definition of pfn_valid() for DISCONTIGMEM
mm, arch: add generic implementation of pfn_valid() for FLATMEM
