I'm thinking you're going to be finding a metric ton of assumptions about 'unsigned long' being 64bit when 64BIT=y throughout the kernel. I know of a couple of places where 64BIT will result in different math such that a 32bit 'unsigned long' will trivially overflow. Please, don't do this. This adds a significant maintenance burden on all of us.
