Subject: [PATCH v2 0/4] mm, arch: add generic implementation of pfn_valid() for FLATMEM
Date: Sun, 29 Jan 2023 14:42:31 +0200	[thread overview]
Message-ID: <20230129124235.209895-1-rppt@kernel.org> (raw)

From: "Mike Rapoport (IBM)" <rppt@kernel.org>

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@kernel.org

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
