Right now on ppc, I may disable the clocks too, but then:

 - As soon as you have implemented the new scheme, I'll replace all that
with using the same hooks as ACPI so that won't be an issue anymore

 - Today, it's probably a non issue too because none of the devices for
which I have that sort of manual clock control also shares interrupts.

Right, but we are fixing that anyway with the noirq phase being AML safe
by no ? :-)

Yup.

Cheers,
