thanks for the patch and the extensive description. I've applied this to
x86.git. Do you agree that this has no urgency for v2.6.24 and is thus
v2.6.25 material?
would you be interested in doing a follow-up patch as well that just
yanks all of the irq compression code? That would keep things nicely
bisectable and testable - the second, larger patch would be a NOP in
theory on most systems.
