stable inclusion from stable-5.10.80 commit 113207234aac0da666ef857c96de6f91d25d443c bugzilla: 185821 https://gitee.com/openeuler/kernel/issues/I4L7CG
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 16520a858a995742c2d2248e86a6026bd0316562 ]
We want to reuse the is_kvm_guest() name in a subsequent patch but with a new body. Hence rename is_kvm_guest() to check_kvm_guest(). No additional changes.
