This patch implements a checker to detect instructions which
should be paravirtualized instead of direct writing raw instruction.
This patch does rough check so that it doesn't fully cover all cases,
but it can detects most cases of paravirtualization breakage of hand
written assembly codes.

paravirtualize minstate.h which are hand written assembly code.
They include sensitive or performance critical privileged
instructions. So that they are appropriate for paravirtualization.

Including asm/hardware.h into asm/io.h can cause #define clashes
between platform specific definitions and driver local definitions.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
