MIPS: Build fix - include <linux/smp.h> into all smp_processor_id() users. 2009-06-24T17:34:39+00:00 Ralf Baechle ralf@linux-mips.org 2009-06-19T13:05:26+00:00 631330f5847b3f8a7ea67d689e9f7c56833ccaa6 Some of the were relying into smp.h being dragged in by another header which of course is fragile. <asm/cpu-info.h> uses smp_processor_id() only in macros and including smp.h there leads to an include loop, so don't change cpu-info.h.

according to Ingo, change set_affinity() in irq_chip should return int,
because that way we can handle failure cases in a much cleaner way, in
the genirq layer.

v2: fix two typos

Impact: change existing irq_chip API

Not much point with gentle transition here: the struct irq_chip's
setaffinity method signature needs to change.

Fortunately, not widely used code, but hits a few architectures.

Note: In irq_select_affinity() I save a temporary in by mangling
irq_desc[irq].affinity directly.  Ingo, does this break anything?
