  docs/kernel-parameters: Update descriptions for "mitigations=" param with retbleed (2022-07-29 20:47:07 +0200)

----------------------------------------------------------------
- Update the mitigations= kernel param documentation

- Check the IBPB feature flag before enabling IBPB in firmware calls
because cloud vendors' fantasy when it comes to creating guest
configurations is unlimited

- Unexport sev_es_ghcb_hv_call() before 5.19 releases now that HyperV
doesn't need it anymore

- Remove dead CONFIG_* items
