Subject: [PATCH] KVM: VMX: Enable machine check support for 32bit targets
Date: Tue, 14 Apr 2020 09:14:14 +0200 [thread overview]
Message-ID: <20200414071414.45636-1-ubizjak@gmail.com> (raw)
There is no reason to limit the use of do_machine_check
to 64bit targets. MCE handling works for both target familes.
