NetBSD/sys/compat/common/kern_info_09.c
christos dcb2a50b2b - Extracted all compat routines from the kern directory and moved here.
- Created compat_util.c and compat_util.h to be used by the compatibility
  modules, so they don't duplicate the same code.
- Added prototypes to the stackgap allocation routines.
