Xen Patches README
------------------

These patches are intended to be stacked on top of genpatches-base.

Many of the patches included here are swiped from various sources which
use their own four digit patch numbering scheme, so we are stuck with five
digits to indiciate the source for easier tracking and re-syncing.

Numbering
---------

0xxxx	Gentoo, not related to Xen. (in case we pull something from extras)
1xxxx	XenSource, upstream Xen patch for 2.6.18
2xxxx	Redhat, we use their Xen patch for >=2.6.20
3xxxx	Debian, we use their security fixes for 2.6.18
5xxxx	Gentoo, Xen and other fixes for Redhat and/or Debian patches.
