[ Upstream commit 82c5b53140faf89c31ea2b3a0985a2f291694169 ]
Currently this driver prints this line with what looks like a rogue format specifier when the device is probed: [ 2.840000] eth%d: MVME147 at 0xfffe1800, irq 12, Hardware Address xx:xx:xx:xx:xx:xx
Change the printk() for netdev_info() and move it after the registration has completed so it prints out the name of the interface properly.

[ Upstream commit b983b271662bd6104d429b0fd97af3333ba760bf ]
Disabling preemption in the GRU driver is unnecessary, and clashes with sleeping locks in several code paths. Remove preempt_disable and preempt_enable from the GRU driver.
