Thanks, I tried your latest nios2 Qemu (v3 series) + patch 2/3 v6 with a 4.8.5
Linux kernel. It still boot :)

Great, thanks ! I'm glad to see it really becomes usable for other
people too :)

I handled the feedback and pushed updated patches to:

Hi Marek,

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:7500 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.
