[PATCH] fix HIPQUAD macro in kernel.h

Hi Dave!

Below is a fix for the HIPQUAD macro in kernel.h. The macro is currently
not endian-aware - it just assumes running on a little-endian machine.

If you don't like the #ifdefs in kernel.h, the macros could be moved into
include/linux/byteorder/.

Please apply, thanks
