[PATCH] fill kvm_callback with arch specific dcr_read/dcr_write callbacks v2

[Christian Ehrhardt]

Subject: [PATCH] fill kvm_callback with arch specific dcr_read/dcr_write callbacks v2
From: Christian Ehrhardt <ehrhardt-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>

This Patch adds the callback assignment and handlers for powerpc_dcr_read
and ppc_dcr_write which are called from libkvm.
This is the part of the patch that changes already submitted code.
Changes in v2:
The function arguments of powerpc_dcr_read/write changed. Since main-ppc.c
is not yet upstream when you check out from kvm-userspace.git I didn't see it.
But Avi replied with "Applied all, thanks." to the three patches from
01/09/2008 bringing main-ppc.c into kvm-userspace this v2 patch includes the
needed code for that file too.

Sorry, I forgot to push after applying.  I'll apply this incrementally.

Or rather, please send a new patch.  I'd rather not risk mucking with 
code I can't compile.

I wrote it a bit misleading, this patch is already the merge of both, so because version 1 is not in the repository you can just add this one which patches all referred issues at once.
I tested it - it still works and matches todays head of kvm-userspace.git.
To be sure I'll resubmit it so you don't need to go through your old mails.
