These flags aren't interchangeable like this, they are dependent on each
other. IRQF_NO_SUSPEND does what it says but IRQF_FORCE_RESUME means
"resume even if IRQF_NO_SUSPEND".
IIRC we want both for IPIs but VIRQ_TIMER needs neither, since the
correct flags are included in IRQF_TIMER already. Nothing else on the
Xen side should be using either flag AFAIK.
However, I don't know of any tree which doesn't have this correct
already. Both Jeremy and Konrad's branches with 2.6.38 in the name are
correct.
I think you need to figure out where you got this tree from (and make
sure you are up to date with it) so we can tell if it is in error or
not.
Ian.
