    arch/riscv: Add functions to read/write memory on behalf of supervisor/user mode
    
    Normally machine-mode code operates completely within physical address
    space. When emulating less privileged memory accesses (e.g. when the
    hardware doesn't support unaligned read/write), it is useful to access
    memory through the MMU (and with virtual addresses); this patch
    implements this functionality using the MPRV bit.
