Hmm, ok. so x86_64 needs a %ld for the pointer arithmic result on i386 needs a %d
without the 'l' what fun. I'll just store it in a temp int variable in the next
version.

I need to do a new version anyways since I ended up going down a bit of a rabithole
wrt the direct IRQ stuff and I now finally completely understand how this all works
including how the trigger bits in the pinctrl work together with the ones in the
IO-APIC. See the next version of this patch for details.

Hans
