Merge branch irq/irq_cpu_offline into irq/irqchip-next
* irq/irq_cpu_offline:
: .
: Make irq_cpu_{on,off}line() deprecated kernel API, and only
: enable it for some obscure Cavium platform after having
: moved all the other users away from it.
:
: Next step, drop the platform itself.
: .
genirq: Hide irq_cpu_{on,off}line() behind a deprecated option
irqchip/mips-gic: Get rid of the reliance on irq_cpu_online()
MIPS: loongson64: Drop call to irq_cpu_offline()
