[PATCH] powerpc/32: Use HAVE_PREEMPT_DYNAMIC_CALL instead of HAVE_PREEMPT_DYNAMIC_KEY
From: "Christophe Leroy (CS GROUP)" <chleroy@kernel.org>

Also in:
lkml
Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Michael Ellerman, Linus Torvalds
powerpc/32 has HAVE_STATIC_CALL_INLINE, so
HAVE_PREEMPT_DYNAMIC_CALL has to be selected instead of
HAVE_PREEMPT_DYNAMIC_KEY for less overhead.
Fixes: 6ad7751537e8 ("powerpc: enable dynamic preemption")
