The patch titled
lguest: export symbols for lguest as a module
has been removed from the -mm tree. Its filename was
lguest-export-symbols-for-lguest-as-a-module.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: lguest: export symbols for lguest as a module
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.
