This patch is not really needed. The build failure on our v3.18-based
kernel is fixed by cherry-picking commit 332fd7c4fef5 ("genirq:
Generic chip: Change irq_reg_{readl,writel} arguments") which is
actually a functional no-op. This patch could help prevent future
build failure in case linux/io.h is later removed from linux/irq.h.
Since the irq-gic-v3 driver uses the read/write io functions, it might
be better to include linux/io.h explicitly.Thanks, Ben On Wed, Aug 19, 2015 at 2:13 PM, Thomas Gleixner <[email protected]> wrote: > On Fri, 7 Aug 2015, Ben Zhang wrote: >> Mainline build is fine because commit 332fd7c4fef5("genirq: Generic >> chip: Change irq_reg_{readl,writel} arguments") landed before the >> timecounter patch, and it creates a new include path to the io.h >> header: >> arch/arm64/include/asm/io.h >> include/linux/io.h >> include/linux/irq.h >> include/linux/of_irq.h >> drivers/irqchip/irq-gic-v3.c > > And why do we need to include it once more then? > > Thanks, > > tglx -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
