Hi all, 
I had posted about MCA support for Intel64 before. It had only a
function to log the MCA error data received from hypervisor.
http://lists.xensource.com/archives/html/xen-devel/2008-09/msg00876.html
I attach patches that support not only error logging but also Page
Offlining function. The page where an MCA occurs will offline and not
reuse. A new flag 'PGC_reserved' was added in page count_info to mark
the impacted page.
I know that it is better to implement the page offlining for general
purpose, but I implemented for MCA specialized in this first step.
And I also implement the MCA handler of Dom0 which support to shutdown
the remote domain where a MCA occurred. If the MCA occurred on a DomU,
Dom0 notifies it to the DomU. When the notify is failed, Dom0 calls
SCHEDOP_remote_shutdown hypercall.
[1/2] xen part: mca-support-with-page-offlining-xen.patch
