[PATCH] Use names, not numbers for pagefault types

This is Bill Irwin's cleanup patch which gives symbolic names to the
fault types:

	#define VM_FAULT_OOM	(-1)
	#define VM_FAULT_SIGBUS	0
	#define VM_FAULT_MINOR	1
	#define VM_FAULT_MAJOR	2

Only arch/i386 has been updated - other architectures can do this too.
