From: Sean Christopherson <seanjc@google.com> stable inclusion from stable-v5.10.102 commit fe383750d40d43d74ffc63f2d695c6f7b9901ff3 bugzilla: https://gitee.com/openeuler/kernel/issues/I567K6 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit dd4589eee99db8f61f7b8f7df1531cad3f74a64d upstream. Remove a WARN on an "AVIC IPI invalid target" exit, the WARN is trivial to trigger from guest as it will fail on any destination APIC ID that doesn't exist from the guest's perspective. Don't bother recording anything in the kernel log, the common tracepoint for kvm_avic_incomplete_ipi() is sufficient for debugging. This reverts commit 37ef0c4414c9743ba7f1af4392f0a27a99649f2a.
