The bulk is adding (and consistently using) specific libxc functions for each XENMEM_* operation. This allows the memory management in xc_memory_op to be greatly simplified by converting it to a purely internal function. Part of this involved adding variants of xc_domain_memory_{increase_reservation,decrease_reservation,populate_physmap} which return the actual number of succesful operations instead of swallowing partial success and converting to failure. Rather than add a difficult to detect API change by redefining the meaning of the integer return value of these types I have instead introduced new names for these functions in the form of xc_domain_{increase_reservation,decrease_reservation,populate_physmap}. In each case I have also added an xc_domain_*_exact variant which maintains the semantics of the old xc_domain_memory_* functions. For consistency xc_domain_memory_{set,get}_pod_target have now become xc_domain_{set,get}_pod_target. The bits which touch ia64 are not even compile tested since I do not have access to a suitable userspace-capable cross compiler. However they are relatively straightforward substitutions. One patch in the series (#11/18) adds a "# XXX update" suffix to QEMU_TAG. Rather than applying directly QEMU_TAG should be updated at this point to include the qemu series posted alongside this one.
