[PATCH 0/4] Add posted interrupt supporting
From: Yang Zhang <yang.z.zhang@Intel.com>
The follwoing patches are adding the Posted Interrupt supporting to Xen:
Posted Interrupt allows vAPIC interrupts to inject into guest directly
without any vmexit.
- When delivering a interrupt to guest, if target vcpu is running,
update Posted-interrupt requests bitmap and send a notification event
to the vcpu. Then the vcpu will handle this

RFC: MCA/MCE concept
Hello!
The current MCA/MCE support in Xen is that it dumps the error and panics.
In the following concept I propose here, there are two places where Xen has to
react on.
I) Xen receives a MCE from the CPU and
II) Xen receives Dom0 instructions via Hypercall
The term "self-healing" below is used in the sense of using the most propriate
technique(s) to handle an error such as MPR
