Subject: [PATCH 04/11] Make display of highmem counters conditional on CONFIG_HIGHMEM
Date: Fri, 7 Jul 2006 16:18:30 -0700 (PDT) [thread overview]
Message-ID: <20060707231830.3790.90912.sendpatchset@schroedinger.engr.sgi.com> (raw)
In-Reply-To: <20060707231810.3790.19313.sendpatchset@schroedinger.engr.sgi.com>
Do not display HIGHMEM memory sizes if CONFIG_HIGHMEM is not set.
Make HIGHMEM dependent texts and make display of highmem counters optional
Some texts are depending on CONFIG_HIGHMEM.
Remove those strings and remove the display of highmem counter values if
CONFIG_HIGHMEM is not set.
