Hi,

v3.17-stable-queue fails to buildavr32:atngw100mkii_evklcd101_defconfig
with the following link error.

vsprintf.c:(.text+0x16dc): relocation truncated to fit: R_AVR32_16N_PCREL against symbol `_ctype' defined in .text section in lib/lib.a(ctype.o)
make: *** [vmlinux] Error 1

Something has grown too large for a 16-bit relative jump. Are you building
with -Os?

Just whatever the default build does; no special configuration.

Culprit is commit "random: add and use memzero_explicit() for clearing data".
I don't see the error upstream. I have no idea why it fails to build in stable-queue,
nor why the build is fine with the upstream kernel.

avr32:defconfig and avr32:merisc_defconfig builds pass without error.

I would suspect atngw100mkii_evklcd101_defconfig enables more stuff than the
other defconfigs, which might explain why. I typically build with only the
set of features I need.

Sadly, no updated toolchain will be available to my knowledge.

Still, it is odd that both the upstream kernel and -next compile.
Any idea why that might be the case ?

Thanks,
Guenter
