Merge tag 'vla-v4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull VLA removal from Kees Cook:
"Globally warn on VLA use.
This turns on "-Wvla" globally now that the last few trees with their
VLA removals have landed (crypto, block, net, and powerpc).
Arnd mentioned that there may be a couple more VLAs hiding in
hard-to-find randconfigs, but nothing big has shaken out in the last
month or so in linux-next.
We should be basically VLA-free now! Wheee. :)
Summary:
- Remove unused fallback for BUILD_BUG_ON (which technically contains
a VLA)
- Lift -Wvla to the top-level Makefile"
* tag 'vla-v4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
Makefile: Globally enable VLA warning
compiler.h: give up __compiletime_assert_fallback()
