With Waldemar Brodkorb and I, we tested this series using 10m50 kernel defconfig
with Buildroot generated system. In order to ease the test, we added the device
tree and a initramfs to the kernel image.

Here is the result:

Welcome to Buildroot
# cat /proc/cpuinfo
CPU:            Nios II/fast
MMU:            present
FPU:            none
Clocking:       75.00 MHz
BogoMips:       150.00
Calibration:    75000000 loops
HW:
 MUL:           yes
 MULX:          no
 DIV:           yes
Icache:         32kB, line length: 32
Dcache:         32kB, line length: 32
TLB:            16 ways, 256 entries, 8 PID bits
# uname -a
Linux buildroot 4.8.1 #2 Fri Oct 14 19:10:18 CEST 2016 nios2 GNU/Linux

When this series will be accepted in Qemu, I'll add a demo defconfig in
Buildroot in order to ease runtime testing.
