From 14612851867e61cf5b46f13aca5a2ce2c329efb6 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Roger=20Pau=20Monn=C3=A9?= Date: Tue, 30 Mar 2021 14:37:53 +0200 Subject: [PATCH] hvm/mtrr: remove unnecessary is_hvm_domain check MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit epte_get_entry_emt will only be called for HVM domains, so the is_hvm_domain check is unnecessary. It's a remnant of PVHv1. Shouldn't result in any functional change.
