Hi, all,

I am trying to map some memory page in DomU kernel space. Specifically, I
am trying to map the in-kernel module structure of sunrpc whose address is
d0848480 and machine address is 00000480. The aligned page becomes zero
(that's weird, I don't know whether that's possible). When I tried to map
it into Dom0, I got an error number -14 which means bad address.

So my question is:
1. Is this kind memory remappable?
2. If so, what's wrong with this? or what's the right way to do that?

Many thanks in advance!
