This patch series adds the Ethernet driver for the Freescale
QorIQ Data Path Acceleration Architecture (DPAA).
This version includes changes following the feedback received
on previous versions from Eric Dumazet, Bob Cochran, Joe Perches,
Paul Bolle, Joakim Tjernlund, Scott Wood, David Miller - th
Introduce managed counterparts for alloc_percpu() and free_percpu().

Some sparse CPUID leafs are gathered in a fake leaf to save size of
x86_capability array in current code, but sometimes, kernel or other
modules (e.g. KVM CPUID enumeration) may need actual hardware leaf
information.

According to pinconf-generic.h, the argument for
PIN_CONFIG_BIAS_PULL_{DOWN,UP} is non-zero if the bias is enabled
with a pull up/down resistor, zero if it is directly connected
to VDD or ground.
Since Allwinner hardware uses a weak pull resistor internally,
the argument should be 1.

The sunxi pinctrl driver only caches whatever pinconf setting was last

I found out recently that this is very helpful when trying to look at
opcodes around the rIP when the segfault happens, and also poke at
architectural registers. When enabled, it looks something like this:
strsep[3702]: segfault at 40066b ip 77abe22b sp 7f

Yeah, you do check CPUID first, AFAICT, so you should be ok...

The fast_switch_enabled flag will be used a bit earlier while converting
the schedutil governor to use kthread worker.
Prepare for that by moving the call to enable it to the beginning of
sugov_init().
