Instead of fixed address in old code.

The patch series add MMIO support to Linux rapidio and fix a few nits.
The patches cross rapidio, netdev, powerpc sub-systems. It will be
good for them to go through one tree. Probably Andrew? As the
previous rapidio patches are mostly merged by you.

Sorry for that. I thought I have added -n when doing the
git-format-patch, but it turns out not the case. :(
Since commit 57b150cce8e004ddd36330490a68bfb59b7271e9, desc->affinity
of an irq is changed after calling desc->chip->set_affinity.
Therefore we need to fix the irq_choose_cpu() not to depend on the
desc->affinity for new mask.

We can't just clear the user read permission in book3e pte, because
that will also clear supervisor read permission. This surely isn't
desired. Fix the problem by adding the supervisor read back.
