Having another look, there are 248 occurrences of the word 'long' in the
.h files under xen/include/public. A search and replace on that is
probably going to break things (eg it would find the word 'belong' too),
but a search and replace on 'unsigned long' (203 occurrences) is
probably safe, leaving 45 'long's to be manually inspected. Nothing like
as big a job as it could have been.

I'll tackle it tonight!
