From: Arnd Bergmann <arnd@arndb.de>

I slightly dropped the ball on this since last sending the series in
August, but a number of warning fixes have made it into the kernel in
the meantime, both from my earlier submission and from architecture
maintainers.

I have none patches that remain from the previous submission, with
two of them reworked according to comments. The additional patches
are from more testing across architectures and configurations that
I had previously missed.

At least one patch is for a newly added warning in recent kernels.

Regarding the regressions in terms of added warnings, there are
now only five architectures left that add warnings (alpha, mips,
nios2, sh and sparc) rather than 15, so I think we can apply
the Kbuild change directly and have the architecture maintainers
take care of the warnings just like the others did already.

As before, my preference would be for the patches to make it
through the respective subsystem maintainer trees, though I
can apply the architecture specific ones to the asm-generic
tree as well.

Sorry for posting these during the merge window, I wanted to
get them out before LPC so we can have them in linux-next
as early as possible.
