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