linux-next is Torvalds master branch?

Weirdly I do not get this when I build torvalds/master with allnoconfig.
The avr32 kernel was never very fond of CONFIG_CC_OPTIMIZE_FOR_SIZE=n, it
was always built with CONFIG_CC_OPTIMIZE_FOR_SIZE=y for actual usage.

Last release of avr32-linux GCC was the 4.2.4 patches in Buildroot for AVR32.
Atmel never upstreamed the AVR32 patches for GCC.

I build the kernel and try to fix small issues here and there.
If it is too unstable for you in the test bench, feel free to remove it.
