The current PMP check function checks for env->priv which is not the effective memory privilege mode. For example, mstatus.MPRV could be set while executing in M-Mode, and in that case the privilege mode for the PMP check should be S-Mode rather than M-Mode (in env->priv) if mstatus.MPP == PRV_S. This patch passes the effective memory privilege mode to the PMP check. Functions that call the PMP check should pass the correct memory privilege mode after reading mstatus' MPRV/MPP or hstatus.SPRV (if Hypervisor mode exists).
