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 Valentin Schneider (2): sparc64: Deselect IRQ_PREFLOW_FASTEOI genirq: Remove preflow handler support arch/sparc/Kconfig | 1 - include/linux/irqdesc.h | 15 --------------- include/linux/irqhandler.h | 1 - kernel/irq/Kconfig | 4 ---- kernel/irq/chip.c | 13 ------------- 5 files changed, 34 deletions(-) -- 2.27.0
