Again, you are missing part of the picture. Yes we -can- fix all the -direct- callers that are obviously only be run at boot time. But what about all the indirect ones (or even direct ones) that can be called either at boot time or later. vmalloc() is the perfect example (or more precisely __get_vm_area() which brings in ioremap etc...) but there are many more.
Cheers, Ben.
