Subject: [PATCH 2/3] mips: drop definition of pfn_valid() for DISCONTIGMEM
Date: Wed, 25 Jan 2023 21:07:56 +0200 [thread overview]
Message-ID: <20230125190757.22555-3-rppt@kernel.org> (raw)
In-Reply-To: <20230125190757.22555-1-rppt@kernel.org>
From: "Mike Rapoport (IBM)" <rppt@kernel.org>
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.
