[PATCH] TRIVIAL: must be __KERNEL__ for byteorder/generic.h

[Rusty Russell]

[ This seems correct for 2.5: noone outside the kernel should be using
  these, and it breaks glibc building in some cases  -- RR ]

[e-mail]: byteorder.h, ntohl, and compiling userspace programs:
  Here's that patch again (MIME this time, so tabs don't get
  lost by my silly gui mailer); applies cleanly against against 2.4.19-pre8.
  Nobody commented on it last time I posted it, and it does
  make compiling gcc easier, so I guess that makes it trivial patch
  monkey fodder.  Or am I making a silly mistake?
