NAME

irq_force_affinity - Force the irq affinity of a given irq

SYNOPSIS

int irq_force_affinity(unsigned int irq, const struct cpumask * cpumask);

ARGUMENTS

irq

DESCRIPTION

Same as irq_set_affinity, but without checking the mask against online cpus.

Solely for low level cpu hotplug code, where we need to make per cpu interrupts affine before the cpu becomes online.
