KVM: SVM: remove INIT intercept handler
Kernel never sends real INIT even to CPUs, other than on boot. Thus INIT interception is an error which should be caught by a check for an unknown VMexit reason. On top of that, the current INIT VM exit handler skips the current instruction which is wrong. That was added in commit 5ff3a351f687 ("KVM: x86: Move trivial instruction-based exit handlers to common code"). Fixes: 5ff3a351f687 ("KVM: x86: Move trivial instruction-based exit handlers to common code") Signed-off-by: Maxim Levitsky <mlevitsk@redhat.com> Message-Id: <20210707125100.677203-3-mlevitsk@redhat.com> Cc: stable@vger.kernel.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
