Subject: [PATCH] mm: don't use ZONE_DMA unless CONFIG_ZONE_DMA is set in setup.c
Date: Tue, 06 Mar 2007 18:52:59 -0500 [thread overview]
Message-ID: <45EDFEDB.3000507@debian.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 184 bytes --]
If CONFIG_ZONE_DMA is ever undefined, ZONE_DMA will also not be defined,
and setup.c won't compile. This wraps it with an #ifdef.
