[PATCH] reduce MAX_NR_ZONES: make display of highmem counters conditional on CONFIG_HIGHMEM

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.

[akpm@osdl.org: remove some ifdefs]
