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?
