Cover letter [RFC PATCH v1 0/3] RISC-V Smstateen support
This series adds support for the Smstateen specification which provides a mechanism to plug potential covert channels which are opened by extensions which add to processor state that may not get context-switched. Currently access to AIA registers and *envcfg registers is controlled via smstateen.
