openwrt/target/linux/brcm63xx/patches-3.14/321-MIPS-BCM63XX-append-irq-line-number-to-irq_-stat-mas.patch
Jonas Gorski b519908e84 brcm63xx: update development kernel to linux 3.14 
Now that 3.13 will be EOL soon, switch to 3.14.

Known issues:
 * 74x164 is not available because upstream dropped non-DT support
 * jffs2 breaks with SMP

Unknown issues:
 * probably plenty

Subject: [PATCH 32/53] MIPS: BCM63XX: append irq line number to
irq_{stat,mask}*
The SMP capable irq controllers have two interupt output pins which are
controlled through separate registers, so make the variables arrays.
