Subject: [PATCH 02/10] sh: mm: remove numa.c
Date: Mon, 13 Apr 2026 13:46:40 +0300	[thread overview]
Message-ID: <20260413104649.852228-3-rppt@kernel.org> (raw)
In-Reply-To: <20260413104649.852228-1-rppt@kernel.org>

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

Since CONFIG_NUMA is removed, numa.c won't be ever compiled.

Remove it.
