Build regressions/improvements in v3.18

From: Geert Uytterhoeven
Date: Mon Dec 08 2014 - 05:25:07 EST

Below is the list of build error/warning regressions/improvements in
v3.18[1] compared to v3.17[2].

Summarized:
- build errors: +16/-15
- build warnings: +134/-78

JFYI, when comparing v3.18[1] to v3.18-rc7[3], the summaries are:
- build errors: +13/-11
- build warnings: +46/-57

Note that there may be false regressions, as the number of configs has
been increased dramatically (from 119 to 262!).
Still, they're build errors/warnings.

As I haven't mastered kup yet, there's no verbose summary at
http://www.kernel.org/pub/linux/kernel/people/geert/linux-log/v3.18.summary.gz

Happy fixing! ;-)

Thanks to the linux-next team for providing the build service.
