[PATCH 0/2] kbuild: remove gcc's -Wtype-limits

[Vincent Mailhol <mailhol@kernel.org>]

I often read on the mailing list people saying "who cares about W=2
builds anyway?". At least I do. Not that I want to fix all of them,
but on some occasions, such as new driver submissions, I have often
found a couple valid diagnostics in the W=2 output.

That said, the annoying thing is that W=2 is heavily polluted by one
warning: -Wtype-limits. Try a gcc W=2 build on any file and see the
results for yourself. I suspect this to be the reason why so few
people are using W=2.

This series removes gcc's -Wtype-limits in an attempt to make W=2 more
useful. Those who do not use W=2 can continue to not use it if they
want. Those who, like me, use it form time to time will get an
improved experience from the reduced spam.

Extra details on statistics, past attempts and -Wtype-limits
alternatives are given in the first patch description.
