Looks like powerpc is missing ARCH_ADD_TRAMP() macro, introduced by
commit 73f44fe19d35 ("static_call: Allow module use without exposing
static_call_key") for x86. I missed it when adding inline static calls
with commit f50b45626e05 ("powerpc/static_call: Implement inline static
calls").
I will have to fix that before we can activate HAVE_PREEMPT_DYNAMIC_CALL.

One more thing to note,
Below series would remove all the EXPORT_STATIC_CALL_TRAMP
instances in scheduler.
That series make sense given that none/voluntary can't be selected now.
