lguest: export symbols for lguest as a module
lguest does some fairly lowlevel things to support a host, which normal modules don't need: math_state_restore: When the guest triggers a Device Not Available fault, we need to be able to restore the FPU __put_task_struct: We need to hold a reference to another task for inter-guest I/O, and put_task_struct() is an inline function which calls __put_task_struct. access_process_vm: We need to access another task for inter-guest I/O. map_vm_area & __get_vm_area: We need to map the switcher shim (ie. monitor) at 0xFFC01000.
