I want to confirm the patches.

Which version of GCC do you use to compile 3.16?

I tried gcc-4.8, it seems that the built kernel can not be boot by qemu.

For my own limited testing, I build for x86 with gcc 4.9. Debian's packages are built with gcc 4.8 (arm) or 4.9 (x86).

Guenter Roeck does build and boot tests on multiple architectures using a variety of (mostly quite recent) compiler versions.
