Excessive time to disable caching with HVM guests with PCI passthrough

ISSUE DESCRIPTION HVM guests are able to manipulate their physical address space such that processing a subsequent request by that guest to disable caches takes an extended amount of time changing the cachability of the memory pages assigned to this guest. This applies only when the guest has bee...
