Re: [Xen-users] Re: Attempt to apply xen-patches-2.6.34-4.tar.bz2 to 2.6.34.7 vanilla

[Andrew Lyon <andrew.lyon@xxxxxxxxx>]

Boris,

The best way to check which kernel version the patches are for is to check the .ebuild, for example:

xen-sources-2.6.34-r3.ebuild

K_GENPATCHES_VER="9"
XENPATCHES_VER="4"

Check 
http://sourcestest.gentoo.org/cgi-bin/viewvc.cgi/linux-patches/genpatches-2.6/tags/2.6.34-9
 and you can see that 2.6.34.5 is the appropriate version.

New patches for .7:

http://gentoo-xen-kernel.googlecode.com/files/xen-sources-2.6.34-r4.ebuild
http://gentoo-xen-kernel.googlecode.com/files/xen-patches-2.6.34-5.tar.bz2

It applies cleanly, but gives errors on kernel build in drivers/base/cpu.c
related with HOTPLUG_CPU=y

I will upload a updated patchset tomorrow, -4 was made before .7 was
out and I'm not surprised that it fails to apply cleanly.

I've been too busy to update the patches much recently but I will try
to do them all this week.
