Other than the name, the vmf_ version takes a pfn_t parameter, and
returns a VM_FAULT_ code suitable for returning from a fault handler.

This patch also prevents vm_insert_pfn() from returning -EBUSY.
This is a good thing as several callers handled it incorrectly (and
none intentionally treat -EBUSY as a different case from 0).

This would be even nicer if you added vmf_insert_pfn as well :)

I've sent out patches adding it before ... my most recent attempt on
January 5th tied up with the DAX support for 1GB pages.  I'll keep
sending it until it sticks :-)
