It would help. The acronym is Machine Check Exception. The patchset
should allow (on newer Intel x86 hw with a newer linux kernel) a class of
memory errors delivered to the host OS as MCEs to be propagated to the
guest OS. Without the patchset, the qemu process assoicated with the
memory where the error took place would be killed. With the patchset,
qemu can propagate the error into the guest and allow the guest to kill
only the process within the guest that is assocated with the memory error.
