-- now hypervisor.h is the universal set of header file, this patch doesn't include hypervisor.h, only include some necessary header files for vm.c and vm.h -- move 'struct vcpuid_entry' from vm.h to vcpuid.h -- remove dead code 'enum vm_privilege_level' -- move 'enum vpic_wire_mode' from vm.h to vpic.h Tracked-On: #1842 Signed-off-by: Mingqiang Chi <mingqiang.chi@intel.com> Reviewed-by: Jason Chen CJ <jason.cj.chen@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
