Merge tag 'gcc-plugins-v4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull GCC plugin updates from Kees Cook:
"The big part is the randstruct plugin infrastructure.
This is the first of two expected pull requests for randstruct since
there are dependencies in other trees that would be easier to merge
once those have landed. Notably, the IPC allocation refactoring in
-mm, and many trivial merge conflicts across several trees when
applying the __randomize_layout annotation.
As a result, it seemed like I should send this now since it is
relatively self-contained, and once the rest of the trees have landed,
send the annotation patches. I'm expecting the final phase of
randstruct (automatic struct selection) will land for v4.14, but if
its other tree dependencies actually make it for v4.13, I can send
that merge request too.
Summary:
- typo fix in Kconfig (Jean Delvare)
- randstruct infrastructure"
