Subject: [PATCH 01/11] swap_prefetch: Remove incorrect use of ZONE_HIGHMEM
Sender: linux-kernel-owner@vger.kernel.org
X-Mailing-List: linux-kernel@vger.kernel.org

swap_prefetch: Remove useless reference to HIGHMEM reserves.

HIGHMEM "reserves" are always zero. Remove the addition of the highmem
reserves.
