[PATCH] mpparse.c:231: warning: comparison is always false

[Jarek Poplawski <jarkao2@o2.pl>]

Hello,

Probably after 2.6.18-rc6-git1 there is this cc warning: 
"arch/i386/kernel/mpparse.c:231: warning: comparison is
always false due to limited range of data type".
Maybe this patch will be helpful.

Jarek P.
