Subject: [PATCH v3 0/3] Refactor memory initialization hardening
Date:   Tue, 23 Apr 2019 12:49:22 -0700
Message-Id: <20190423194925.32151-1-keescook@chromium.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This refactors the stack memory initialization configs in order to
keep things together when adding Clang stack initialization, and in
preparation for future heap memory initialization configs.

I intend to carry this in the gcc-plugins tree, but I'd really like
to get Acks from Masahiro (Kconfig changes, Makefile change), and
from James (adding the new Kconfig.hardening to security/Kconfig).

Thanks!

-Kees

v3:
- clean up menu/if with a merged "depends on" (masahiro)
- add CONFIG_COMPILE_TEST defaults (masahiro)

v2:
- add plugin menu (masahiro)
- adjust patch subject prefixes (masahiro)
- drop redundent "depends" (masahiro)
- fixed early use of CC_HAS_AUTO_VAR_INIT (masahiro)
- dropped default-enabled for STACK_INIT_ALL (masahiro)
