Several memory hypercall operations allow invalid extent order values

ISSUE DESCRIPTION Allowing arbitrary extentorder input values for XENMEMdecreasereservation, XENMEMpopulatephysmap, and XENMEMexchange can cause arbitrarily long time being spent in loops without allowing vital other code to get a chance to execute. This may also cause inconsistent state resultin...
