Hi,
while strolling around the different flow handlers, I tried to make
sense of
what preflow_handler() was about. Turns out no one uses those anymore,
but the
genirq support has remained in place.
If we needed to reintroduce some form of preflow handler, we'd try and
do it using hierarchical irqchips, if at all possible.
Unless we can see another user of those in the near future, this seems
like as
good a time as any for a little housecleaning.
- Patch 1 simply deselects the (unexploited) preflow Kconfig for
sparc64
- Patch 2 is the actual cleanup
Cheers,
Valentin

For the whole series, and assuming that there is no regression
