This looks really ugly. PAGE_OFFSET is usually a macro.
I looked in patch 29/52 where PAGE_OFFSET is defined (unsigned int 
PAGE_OFFSET), which got me wondered: PAGE_OFFSET can be a runtime 
variable when it is a constant on most other arches?

That being said, I'd use

#define PAGE_OFFSET __page_offset

in some header file and in the .c file:

	unsigned int __page_offset;
	EXPORT_SYMBOL(__page_offset);

that is how arch-frv and -uml seem to do it.
