Subject: lguest preparation: EXPORT_SYMBOL_GPL 5 functions
From: Rusty Russell <rusty@xxxxxxxxxxxxxxx>
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.
