Date: Thu, 30 Jun 2022 15:46:59 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Paolo Bonzini <pbonzini@...hat.com> Subject: [PATCH 5.15 03/28] x86, kvm: use proper ASM macros for kvm_vcpu_is_preempted From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> The build rightfully complains about: arch/x86/kernel/kvm.o: warning: objtool: __raw_callee_save___kvm_vcpu_is_preempted()+0x12: missing int3 after ret because the ASM_RET call is not being used correctly in kvm_vcpu_is_preempted(). This was hand-fixed-up in the kvm merge commit a4cfff3f0f8c ("Merge branch 'kvm-older-features' into HEAD") which of course can not be backported to stable kernels, so just fix this up directly instead.
