#include "VIS.h"

	/* VIS code can be used for numerous copy/set operation variants.
	 * It can be made to work in the kernel, one single instance,
	 * for all of memcpy, copy_to_user, and copy_from_user by setting
	 * the ASI src/dest globals correctly.  Furthermore it can
	 * be used for kernel-->kernel page copies as well, a hook label
	 * is put in here just for this purpose.
	 *
	 * For userland, compiling this without __KERNEL__ defined makes
	 * it work just fine as a generic libc bcopy and memcpy.
	 * If for userland it is compiled with a 32bit gcc (but you need
	 * -Wa,-Av9a for as), the code will just rely on lower 32bits of
	 * IEU registers, if you compile it with 64bit gcc (ie. define
	 * __sparc_v9__), the code will use full 64bit.
