Peter Zijlstra b24fdd0f1c x86/retbleed: Add fine grained Kconfig knobs ... commit f43b9876e857c739d407bc56df288b0ebe1a9164 upstream. Do fine-grained Kconfig for all the various retbleed parts. NOTE: if your compiler doesn't support return thunks this will silently 'upgrade' your mitigation to IBPB, you might not like this.
