The dom0_ops implementation wasn''t matching the interface definition, leading to ill messages when X starts up (and potentially to other problems). The attached patch fixes that. However, it also points out that there is a potential disagreement between the dom0_ops interface and the internal MTRR interface - the former expects an unsigned register number from the domain, the latter wants a signed one and does a lookup when it''s negative. I would think that the lookup code should just be ripped out of xen/arch/x86/mtrr/main.c.
