hi, the IO-APIC code got unified in the x86 tree for v2.6.28.

So could you please send the fix against tip/master:

  http://people.redhat.com/mingo/tip.git/README

Thanks,

I can't see this as required for tip. FIRST_DEVICE_VECTOR is there defined
distinct to the ISA IRQs (IRQ15_VECTOR+2) while it is defined to be equal to
IRQ0_VECTOR on 2.6.27 and before (at least down to 2.6.24).

Regards,
Stefan

Hi Ingo,

I didn't see any follow up, so for clarification: there is nothing to
fix in tip but the bug is there in kernels between 2.6.24 and 2.6.27.
Could you push it to 2.6.27 and possibly to the stable trees?

Stefan

it's too late for v2.6.27 - this bug permeates so many kernel versions 
that it's clearly not in the '2.6.27 regression' category. But it can be 
asked to be included in -stable after v2.6.27 is released.
