[Xen-devel] [Patch] Add MCA recovery action support in XEN

["Ke, Liping" <liping.ke@xxxxxxxxx>]

Hi, all
 
This patch is to support MCA recovery actions for latest Intel Platform.

When an UC = 1 PCC = 0 MCE happens, there're more types of software 
recoverable error defined on on latest Intel Platform. For identifying those 
new errors, some new bit (S/AR bit) is defined in MCi_STATUS register. 
Also we need MCACOD help's to judge the detailed error. Combined with 
the OVER bit, different recovery policies are required for containing those 
new errors.

SRAO error  is an software recoverable MCA error, no recovery action 
required. while SRAR  is an software recoverable MCA error, recovery 
action is required.

Thanks& Regards,
Criping
