# commit 746bb4ed6d626f3f9e431a7f9b20504538e62ded
# Merge: ac747c0715f2 0bb95f80a38f
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Sun Oct 28 13:26:45 2018 -0700

#     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()
