Likely, PPC and PowerPC already use the new genirq. It is likely used under PPC as far it has to be: renamed structures, moved information. But the core issue is if the flow handling (edge, level, simple etc.) also moved to kernel/irq/chip.c, and that looks to me like only being the case for PowerPC.

I have an x86_64 box waiting for a Xenomai port - I don't see much point in hacking 2.6.17 and earlier when 2.6.19 is going to be a major change in key areas.. It also looks like there is a closer integration of x86_64 and plain old ix86 code in the 2.6.19 tree, so this may simplify the task of maintaining a 64bit patch.

Still, any patches/hints about additionally required flags for PPC are welcome! against some Xenomai installation (make XENO=..., unless xeno-config is already in $PATH) or a Xenomai-kernel (make KSRC=...). Moreover, there is simple Makefile under /examples just to kick building/cleaning of all subdirs at once. If it's OK for everyone, I would check this into trunk.
