[PATCH 00/12] kbuild: enable some -Wextra warnings by default

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

This is a follow-up on a couple of patch series I sent in the past,
enabling -Wextra (aside from stuff that is explicitly disabled),
-Wcast-function-pointer-strict and -Wrestrict.

I have tested these on 'defconfig' and 'allmodconfig' builds across
all architectures, as well as many 'randconfig' builds on x86, arm and
arm64. It would be nice to have all the Makefile.extrawarn changes in
v6.10, hopefully with the driver fixes going in before that through
the respective subsystem trees.
