Subject: [GIT PULL] hardening updates for v6.13-rc1
Hi Linus,
Please pull these hardening updates for v6.13-rc1. I delayed sending
this for several days just to make sure the Kconfig and compiler.h
changes got a little more bake-time in -next since they were added to my
tree pretty late in the cycle. All seems well, so here's the PR.
Thanks!
-Kees
