Note that PREEMPT_DYNAMIC is `def bool y`, so this will default to
enabled.
It should probably be "def_bool y if HAVE_STATIC_CALL_INLINE"...
Sure; I'm more than happy to fold that into patch 5.
For the moment I've made that:

	def_bool y if HAVE_PREEMPT_DYNAMIC_CALL

... since that fit more neatly with the other bits I had to add, and didn't
change the existing behaviour of 32-bit x86.

Please shout if you think that should be HAVE_STATIC_CALL_INLINE specifically!
I seem to remember peterz didn't mind keeping it default y as long as
HAVE_STATIC_CALL*. So I guess that's fine.

Thanks!
