From db205f7e1edc8d8f0880f0218d3a03b13fe94af3 Mon Sep 17 00:00:00 2001 From: Aaron Lewis Date: Wed, 21 Sep 2022 15:15:22 +0000 Subject: KVM: x86: Add a VALID_MASK for the MSR exit reason flags Add the mask KVM_MSR_EXIT_REASON_VALID_MASK for the MSR exit reason flags. This simplifies checks that validate these flags, and makes it easier to introduce new flags in the future. No functional change intended.
