| * MIPS: RB532: provide GPIO_BUILTIN_NR and irq_to_gpio/gpio_to_irqFlorian Fainelli2008-10-111-7/+7
| | | | | | | | | | | | | | | | | | | | | | This patchs defines the number of built-in the GPIOs present on the SoC as Documentation/gpio.txt recommends to do. Define irq_to_gpio/gpio_to_irq to return the right values so that it fixes a compilation error on drivers/gpio/gpiolib.c when enabling debugfs.

Various kernel function would need that notification, e.g. kvm works around by calling smp_call_function_single(), rcu polls cpu_online_map. The patch adds a CPU_STARTING notification. It also adds a helper function that sends the message to all cpu_chain handlers. Tested on x86-64. All other archs are untested. Especially on sparc, I'm not sure if I got it right.
