I am working on a consolidated patch set for AKMP. It integrates all
fixes and adds a config option CONFIG_X86_REROUTE_FOR_BROKEN_BOOT_IRQS
(prepared by Stefan Assmann), which can default to off for vanilla and to
on for RT / threaded IRQ handling. This means that the whole patchset
can (in principle) be applied to vanilla and RT without change. Also
CONFIG_PREEMPT_HARDIRQ can "select CONFIG_X86_REROUTE_FOR_BROKEN_BOOT_IRQS".

If you don't mind, I will send the full set out today.
