Subject: [PATCH 0/3] mm, arch: add generic implementation of pfn_valid() for FLATMEM
Date: Wed, 25 Jan 2023 21:07:54 +0200 [thread overview]
Message-ID: <20230125190757.22555-1-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
Mike Rapoport (IBM) (3):
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
