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" * tag 'gcc-plugins-v4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: ARM: Prepare for randomized task_struct randstruct: Whitelist NIU struct page overloading randstruct: Whitelist big_key path struct overloading randstruct: Whitelist UNIXCB cast randstruct: Whitelist struct security_hook_heads cast gcc-plugins: Add the randstruct plugin Fix English in description of GCC_PLUGIN_STRUCTLEAK compiler: Add __designated_init annotation gcc-plugins: Detail c-common.h location for GCC 4.6
