Principle of minimum damage. The alternative is to find a way to introduce in_interrupt()
much earlier in the build. The original code tried that and failed. So did I.
Please note that all the functions in mmx.c are similar in nature. The PREFETCH call for
those big L1 lines is a great compensator.
If you have a patch which preserves __inline__ and builds, too, I'd be delighted to test
it.

Tom
