Subject: [PATCH 0/2] genirq: Kill preflow handlers

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.

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
