Subject: [PATCH] Add NUMA_BUILD definition in kernel.h to avoid #ifdef CONFIG_NUMA
X-Git-Tag: v2.6.19-rc1~970
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=08e0f6a9705376732fd3bc9bf8ba97a6b5211eb1;p=pandora-kernel.git

[PATCH] Add NUMA_BUILD definition in kernel.h to avoid #ifdef CONFIG_NUMA

The NUMA_BUILD constant is always available and will be set to 1 on
NUMA_BUILDs.  That way checks valid only under CONFIG_NUMA can easily be done
without #ifdef CONFIG_NUMA

F.e.

if (NUMA_BUILD && <numa_condition>) {
...
}

[akpm: not a thing we'd normally do, but CONFIG_NUMA is special: it is
 causing ifdef explosion in core kernel, so let's see if this is a comfortable
 way in whcih to control that]
