Subject: [PATCH] x86: cpu_khz type fix
X-Git-Tag: v2.6.13-rc1~68^2~486
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a3a255e744dfa672e741dc24306491139d0de2d8;p=linux-2.6

[PATCH] x86: cpu_khz type fix

x86_64's cpu_khz is unsigned int and there is no reason why x86 needs to use
unsigned long.

So make cpu_khz unsigned int on x86 as well.
