Subject: [GIT PULL] VLA removal for v4.20-rc1

Hi Linus,

Please pull these VLA removal changes for v4.20-rc1. 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. :)

Thanks!

-Kees
