[Xen-devel] [GIT PULL] (xen) stable/for-linus-3.7-rc7-tag

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

Hey Linus,

I've one fix for which I got the Tested-by right after I sent you a git pull on
Friday. If you have some extra patches for rc7, please consider pulling it.
If you don't have any - I will just stick this in my for-v3.7.

stable/for-linus-3.6-rc7-tag

It is a bug-fix when we run the initial PV guest on a AMD K8 machine
and have CONFIG_AMD_NUMA enabled and detect the NUMA topology from the 
Northbridge.

We end up in the situation where the initial domain gets too much information
and gets confused and crashes - the fix is to restrict the domain to get the
information - and we do it by just disabling NUMA on the PV guest (the 
hypervisor is
still able to do its proper NUMA allocations of guests). It is OK to disable 
the PV
guest from accessing NUMA data as right now we do not inject any NUMA node 
information
to the PV guests. When we do get to that point, then this patch will have to be 
reverted.

Konrad Rzeszutek Wilk (1):
      xen/boot: Disable NUMA for PV guests.
