MIPS: Octeon: Rewrite interrupt handling code.
This includes conversion to new style irq_chip functions, and correctly enabling/disabling per-CPU interrupts. The hardware interrupt bit to irq number mapping is now done with a flexible map, instead of by bit twiddling the irq number. [ tglx: Adjusted to new irq_cpu_on/offline callbacks and __irq_set_affinity_lock ] Signed-off-by: David Daney <ddaney@caviumnetworks.com> Cc: linux-mips@linux-mips.org Cc: ralf@linux-mips.org LKML-Reference: <1301081931-11240-5-git-send-email-ddaney@caviumnetworks.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
