Hi Guenter,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 168309855a7d1e16db751e9c647119fe2d2dc878
commit: 398c7500a1f5f74e207bd2edca1b1721b3cc1f1e MIPS: VDSO: Fix build error with binutils 2.24 and earlier
date: 6 days ago
config: mips-jmr3927_defconfig (attached as .config)
reproduce:
wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout 398c7500a1f5f74e207bd2edca1b1721b3cc1f1e
# save the attached .config to linux build tree

FWIW, I tested my patch with the compiler from Yocto 2.0, which uses gcc 5.2.0 and binutils 2.25.1, with no problem. Do you have directions on how to install a debian cross compiler into a Ubuntu system ? Alternatively, what version of binutils does the mips cross compiler use ?

This is interesting, I'll do more checks. > The problem is an interesting one: Due to my patch, arch/mips/vdso/gettimeofday.c actually compiles with your toolchain (as it should, since its binutils version is >= 2.25). Previously that was not the case. In other words, my patch exposes a previously existing problem. The underlying problem seems to be that your toolchain, as the error suggests, does not support '-march=r3900' (which is set with the affected configuration) without '-mfp32'. This may be a problem only for gettimeofday.c because that file is compiled with different options than everything else. I _suspect_ the reason to be that -msoft-float and -Wa,-msoft-float are dropped from the gettimeofday compile options, but I am not sure. Ralf and/or Alex (copying) may have a better understanding of the problem.
