Subject: [PATCH] fill kvm_callback with arch specific dcr_read/dcr_write
callbacks
From: Christian Ehrhardt <[EMAIL PROTECTED]>
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 while the
implementation will follow as one when kvm-userspace for ppc is finished, but
appyling this now will reduce the changes to non-ppc files later in the big
patch.
