[grsec] backporting fixes to older kernels

[Natanael Copa]

Hi,

I use a vserver+grsecurity patch from http://linux-vserver.org

The latest stable vserver patch is for 2.6.22, but this one does not
work on some hardware, inclusive qemu/kvm. IIRC there was some issues
with some pax kernels that was fixed in newer releases.

I wonder if there is a way to trace the changes in the grsecurity
patches so I can backport a fix for 2.6.22.

Other suggestions?
