Hi Dave, Ingo,

Today's linux-next build (sparc64 defconfig) failed like this:

arch/sparc/kernel/nmi.c: In function 'perfctr_irq':
arch/sparc/kernel/nmi.c:97: error: 'struct kernel_stat' has no member named 'irqs'

Probably caused by commit e5553a6d04421eec326a629571d696e8e745a0e4
("sparc64: Implement NMI watchdog on capable cpus") from the
sparc-current tree interacting with commit
d7e51e66899f95dabc89b4d4c6674a6e50fa37fc ("sparseirq: make some func to
be used with genirq") from the sparseirq tree.

I have temporarily applied the patch below.  I don't know if it is
correct (but it fixes the build).  If it is, it should be applicable to
the sparc-current tree as the needed interface exists in Linus' current
tree.
