[PATCH 4.9 45/80] KVM: VMX: Enable machine check support for 32bit targets

From: Greg Kroah-Hartman
Date: Fri May 01 2020 - 09:29:52 EST


From: Uros Bizjak <ubizjak@xxxxxxxxx>

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.
