Merge tag 'gcc-plugins-v4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull gcc-plugins update from Kees Cook:
"Both arm and arm64 are gaining per-task stack canaries (to match x86),
but arm is being done with a gcc plugin, hence it going through the
gcc-plugins tree.
New gcc-plugin:
- Enable per-task stack protector for ARM (Ard Biesheuvel)"
* tag 'gcc-plugins-v4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
ARM: smp: add support for per-task stack canaries
