Yay!

Is CONFIG_CFI_PERMISSIVE=y expected to work with this series?

I wasn't able to build with CONFIG_FTRACE=y; I got this link error:

ld.lld: error: undefined symbol: ftrace_stub_graph

(FWIW, I'm building against v6.8-rc2, maybe I need a different base?)

But yes, I can boot and prototype mismatches are caught. Whee! :)
