Ideally, Yes. But I guess the first purpose of mm_switch_table was
sanity checking of guest OS's behavior. So I don't want to touch it.
And besides I'm conservative. 
Although replacing SW_NOP to SW_2PT_DT may work, the meaning will be lost.

Indeed SW_NOP had better be fixed. 
But physical emulation only for instruction is not implemented yet
and I don't think it's easy to support it. Testing is a difficulty.

It's enough for me for the moment.

Thanks,
Kouya
