Subject: drivers: net: gianfar: Make RT aware
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/3.12/patches-3.12.0-rt2.tar.xz
The adjust_link() disables interrupts before taking the queue
locks. On RT those locks are converted to "sleeping" locks and
therefor the local_irq_save/restore must be converted to
local_irq_save/restore_nort.
