This snapshot includes new ppc and ppc64 support written and tested by Christoph Hellwig. the core bits were reworked quite significantly. Changes: - split up kernel/hardirq.c into individual files in kernel/irq/ - 80-90% of each converted architecture's irq.c file is now eliminated by this patch. The most dramatic one is x64's irq.c - a mere 108 lines remained. The total effect on the 4 architectures covered so far: more than 3000 lines of irq.c code removed while kernel/irq/*.c remains around 1000 lines of code. - more irq.h, interrupt.h, asm/hardirq.h and linux/hardirq.h consolidation from Christoph and me. - thorough cleanup of the generic irq code. - compile-testing of the following architectures: x86, x64, ppc64, ppc, ia64, s390, s390x. The first four were boot-tested as well. there are 5 patches that will follow in the next 5 mails: generic-hardirqs-core.patch generic-hardirqs-x86.patch generic-hardirqs-x64.patch generic-hardirqs-ppc.patch generic-hardirqs-ppc64.patch note that it is still a goal of the patchset to not break the building of any non-CONFIG_GENERIC_HARDIRQS platform - 3 such platforms were compile-tested. comments welcome, Ingo
