Ok, not that bad, only 4:
	383fb3ee8024 ("ARM: spectre-v2: per-CPU vtables to work around big.Little systems")
	e209950fdd06 ("ARM: add PROC_VTABLE and PROC_TABLE macros")
	945aceb1db88 ("ARM: clean up per-processor check_bugs method call")
	899a42f83667 ("ARM: make lookup_processor_type() non-__init")

I'll go drop them all from the trees now.  Turns out for 4.14 one of
these patches broke the build anyway.  Sasha, how did that past your
builder tests?

thanks,
