/* The files syswrap-generic.c, syswrap-linux.c, syswrap-*-linux.c,
   and associated vki*.h header files, constitute Valgrind's model of how a
   vanilla Linux kernel behaves with respect to syscalls.

   On a few occasions, it is useful to run with a kernel that has some
   (minor) extensions to the vanilla model, either due to running on a
   hacked kernel, or using a vanilla kernel which has incorporated a
   custom kernel module.  Rather than clutter the standard model, all
   such variant handlers are placed in here.

   Unlike the C files for the standard model, this file should also
   contain all constants/types needed for said wrappers.  The vki*.h
   headers should not be polluted with non-vanilla info. */
