According to mingo's patch set, HRTIMER_REL and HRTIMER_ABS were
simply renamed to HRTIMER_MODE_REL and HRTIMER_MODE_ABS. Since these
are enums instead of macros, a little #ifndef/#define hack would not
work. Unless the RT patches identify themselves at compile time, it
may be tricky to generate code that works with both base and patched
kernel.
