Subject: [PATCH 5.6 114/167] KVM: VMX: Enable machine check support for 32bit targets
From: Uros Bizjak <ubizjak@...il.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.
