The problem is that 'git bisect' did not produce a valid result for
me. It says that:

commit cf377ad7d42c566356d79049536d9cb37499cb77
Merge: 212fe84 d8f0faa
Author: Linus Torvalds <torvalds at linux-foundation.org>
Date:   Wed Oct 8 17:13:04 2014 -0400

    Merge tag 'soc-for-linus' of
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc


, is the first bad commit, but this does not look correct, so I was
not able to really identify the commit that caused this regression.

Here is my procedure (starting at 3.18-rc1):

git bisect start
git bisect bad
git bisect good v3.17
make imx_v6_v7_defconfig
cat .config | grep CONFIG_SPI=y

Then I add "git bisect good or bad" depending on the output of the
'cat' command.

Any ideas?
