* x86: paravirt_ops: don't steal memory resources in paravirt_disable_iospaceJeremy Fitzhardinge2008-04-171-17/+1
| | | | | | | | | | The memory resource is also used for main memory, and we need it to allocate physical addresses for memory hotplug. Knobbling io space is enough to get the job done anyway.

| | | | | | | | | | paravirt_pagetable_setup_{start,done}() are not used (yet) under x86_64, and native_pagetable_setup_{start,done}() don't exist on x86_64. So they don't need to be set.
