So my inclination is to revert the powerpc stack protector code for
4.10, and we can try again for 4.11 or 12.
That makes sense. We then wait for the right gcc version? I guess we also
push for per-task gaurd value as opposed to a global one?
Global value will work (with GCC 7) as-is. Per-task will require some
kernel work, but yeah you want it, that is why the options for that exist ;-)
You don't have to revert the current stack protector code; just condition it
on the relevant GCC flags (you will need to do that later anyway).
