From ecc513e5bb7ed5d007dcaa533729360e9eb673ba Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Wed, 9 Jun 2021 11:56:19 -0700 Subject: [PATCH] KVM: x86: Drop "pre_" from enter/leave_smm() helpers Now that .post_leave_smm() is gone, drop "pre_" from the remaining helpers. The helpers aren't invoked purely before SMI/RSM processing, e.g. both helpers are invoked after state is snapshotted (from regs or SMRAM), and the RSM helper is invoked after some amount of register state has been stuffed.
