With the current implementation, if we had the following scenario: - Set bit x in menvcfg - Set bit x in henvcfg - Clear bit x in menvcfg then, the internal variable env->henvcfg would still contain bit x due to both a wrong menvcfg mask used in write_henvcfg() as well as a missing update of henvcfg upon menvcfg update. This can lead to some wrong interpretation of the context. In order to update henvcfg upon menvcfg writing, call write_henvcfg() after writing menvcfg. Clearing henvcfg upon writing the new value is also needed in write_henvcfg() as well as clearing henvcfg upper part when writing it with write_henvcfgh().
