[PATCH 5.4 119/168] KVM: VMX: Enable machine check support for 32bit targets
From: Greg Kroah-Hartman
Date: Tue Apr 28 2020 - 14:42:50 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.
