Subject: [PATCH] Drop an empty byteorder/generic.h from being exported to
 userspace.


Since the entire meaningful contents of generic.h is wrapped by the
__KERNEL__ test, drop it from being passed to userspace, and remove
the now superfluous __KERNEL__ test.

Signed-off-by: Robert P. J. Day <rpjday@...shcourse.ca>

  is there some value in allowing an effectively empty header file to
be exported to userspace?
