Because it makes for dumb code. But oh well, given that it all compiles 
to basically nothing I guess I'll stop objecting.

Andrew: The attached removes the assumption that if the first page of an 
ISA ROM is mapped, it'll all be mapped. This'll also stop people reading 
this code from wondering if they're looking at a bug.

This replaces "romsignature-checksum-cleanup.patch" in current -mm.
