Subject[PATCH 4.4 40/70] KVM: VMX: Enable machine check support for 32bit targets
Date
From: Uros Bizjak <ubizjak@gmail.com>

commit fb56baae5ea509e63c2a068d66a4d8ea91969fca upstream.

There is no reason to limit the use of do_machine_check
to 64bit targets. MCE handling works for both target familes.
