commit 29ed6d4e5e79fb9a38041875efe0efeb09b8f87a Author: Aaron Durbin adurbin@chromium.org Date: Thu Nov 14 11:15:43 2013 -0600
rambi: distribute IRQs away from PIRQA on pci devices
Some of the drivers in the kernel were not so happy about having shared IRQs. Also, sharing IRQs means more code needs to be run in interrupt context to determine if the IRQ was meant for a particular device. Fix this.
No more 'mmc1: got irq while runtime suspended' messages.
BUG=chrome-os-partner:24056 BRANCH=None TEST=Built and booted. Looked at /proc/interrupts and noted no more sharing between pci devices.
