These seem to be largely caused by building with gcc-6. It's probably a good idea to keep supporting that configuration though and backport the fixes. Here are the upstream commit IDs I've found.
That's a lot of noise. I'll move back to build with gcc 4.9.2 instead, for now.
It's not entirely reasonable to expect older releases to build with new toolchains without warnings, and I'm not sure if it makes sense to bring back those fixes to -stable (unless they fix real bugs, of course).
My test-builder system is using gcc-6, and I do keep track of warnings as it is a good indication that an applied patch is wrong (found a bug in an i2c patch just yesterday because of it.)
I'm currently seeing only 3 warnings on x86 for 4.4-stable and gcc-6, and just found the fix for one of them, so I'll gladly take warning fixes that resolve issues to make it easier for the real problems to jump out at us.
