From 5992b6dac0d23a2b51a1ccbaf8f1a2e62097b12b Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 19 Jul 2007 01:49:21 -0700 Subject: 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.
