Subject: disable new gcc-7.1.1 warnings for now

From: Linus Torvalds <[email protected]>

commit bd664f6b3e376a8ef4990f87d08271cc2d01ba9a upstream.

I made the mistake of upgrading my desktop to the new Fedora 26 that comes with gcc-7.1.1.

There's nothing wrong per se that I've noticed, but I now have 1500 lines of warnings, mostly from the new format-truncation warning triggering all over the tree.

We use 'snprintf()' and friends in a lot of places, and often know that the numbers are fairly small (ie a controller index or similar), but gcc doesn't know that, and sees an 'int', and thinks that it could be some huge number. And then complains when our buffers are not able to fit the name for the ten millionth controller.

These warnings aren't necessarily bad per se, and we probably want to look through them subsystem by subsystem, but at least during the merge window they just mean that I can't even see if somebody is introducing any *real* problems when I pull.

So warnings disabled for now.
