Heh. That looks very unlikely, so the bisection seems to sadly have
failed at some point.

At least one of the KASAN reports (that "final oops") does look very
much like the bug fixed by commit 1bff51ea59a9 ("Bluetooth: fix
use-after-free error in lock_sock_nested()"), so this may already be
fixed, but who knows...

But that "update Makefile to 4.10" is not the cause...
