Thanks, I'll apply that to the 3.14-stable tree, but, it doesn't seem relevant at all for 3.10-stable as arch/arm64/kernel/irq.c doesn't do anything with cpumask or set_affinity. If it's relevant for 3.10, please provide a backported version. > Unfortunately there is not an equivalent fix for arm - Russell objected > to the approach [2,3,4], and that's not yet settled. Ok, be sure to cc: stable on the patch when it goes into the tree and I'll pick it up then. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
