Build regressions/improvements in v3.12-rc4

From: Geert Uytterhoeven
Date: Mon Oct 07 2013 - 15:23:58 EST

Below is the list of build error/warning regressions/improvements in
v3.12-rc4[1] compared to v3.11[2].

Summarized:
- build errors: +26/-12
- build warnings: +132/-99

JFYI, when comparing v3.12-rc4 to v3.12-rc3[3], the summaries are:
- build errors: +6/-10
- build warnings: +29/-42

As I haven't mastered kup yet, there's no verbose summary at
http://www.kernel.org/pub/linux/kernel/people/geert/linux-log/v3.12-rc4.summary.gz

Happy fixing! ;-)

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