PATCH 1/1 PV drivers can be compiled on CentOS 5.x without any modifications.

Hi all,

Since I could not compile PV drivers on CentOS 5.2, I have implemented small patch (attached) to platform-compat.h and overrides.mk.

I have tested this patch on both CentOS 5.2 and Debian etch, and it works well.
Will you review it?

Thank you in advance,
Yoshisato YANAGISAWA.
