Subject: [PATCH v3 0/3] Refactor memory initialization hardening

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).



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

- 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)

Kees Cook (3):
  security: Create "kernel hardening" config area
  security: Move stackleak config to Kconfig.hardening
  security: Implement Clang's stack initialization
