System errors such as SLB multihit and memory errors that cannot be corrected by hardware is passed on to the kernel for handling by raising machine check exception (an NMI). Upon such machine check exceptions, if the address in error belongs to guest then KVM invokes guests' 0x200 interrupt vector if the guest is not FWNMI capable. For FWNMI capable guest KVM passes the control to QEMU by exiting the guest. This patch series adds functionality to QEMU to pass on such machine check exceptions to the FWNMI capable guest kernel by building an error log and invoking the guest registered machine check handling routine. The KVM changes are now part of the upstream kernel (commit e20bbd3d). This series contain QEMU changes.
