From 9638cbde6c4f433b157672c0fdee783c10be45fe Mon Sep 17 00:00:00 2001 From: =?utf8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Tue, 4 Apr 2023 11:15:05 +0200 Subject: [PATCH] target/riscv: Restrict KVM-specific fields from ArchCPU MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit These fields shouldn't be accessed when KVM is not available. Restrict the KVM timer migration state. Rename the KVM timer post_load() handler accordingly, because cpu_post_load() is too generic.
