Oh, sorry for the late reply, was busy with stuff.
It's linear, there are (after applying the series) some static
inlines in arch/m68k/include/asm/bitops.h (those which were
converted from macros in patch 3/6), 7 ops in total, you just need
to create definitions with 'arch_' prefix for each of them, e.g.

#define arch_test_bit	test_bit
#define arch___set_bit	__set_bit // will be ___set_bit after 5/6

etc.
Hope I explained it clear-ish :)
