From aff3ccd7320eed5814d317fcb80244f474d66a84 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Sat, 28 May 2022 12:38:21 +0100 Subject: [PATCH] KVM: arm64: Move vcpu ON_UNSUPPORTED_CPU flag to the state flag set The ON_UNSUPPORTED_CPU flag is only there to track the sad fact that we have ended-up on a CPU where we cannot really run. Since this is only for the host kernel's use, move it to the state set.
