I checked the parisc warnings, and looking at
it seems a gcc-4.6 (/opt/cross/gcc-4.6.3-nolibc/hppa-linux/bin/hppa-linux-gcc) compiler
is still being used.
I tend to think, that gcc-4.6 wasn't able to generate function sections
which is why we see those warnings now (there was a FTRACE patch from me
included before v4.6-rc4).
Anyway, I can't reproduce those warnings with gcc-4.8 and higher.
Given the fact, that we even switched on debian now to use gcc-5 for the kernel, can
someone please update the 32- and 64-bit parisc compilers on the kiss
infrastructure to at least gcc-4.8 (gcc-4.9 or gcc-5 being preferred).
