Probably a lot... Which is one of the reasons linux-next exists.. . ;-)
Actually, Paul Gortmaker caused this breakage with the commit. He should
take a deeper look and see what it broke. From his commit:
Most of the implicit dependencies on module.h being present by
these headers pulling it in have been now weeded out, so we can
finally make this change with hopefully minimal breakage.
