If you are not working with a file system then I would suggest

That's probably not a good suggestion; the UBC implementation does
not use KPI. If the page is sourced from an address space (as I
inferred from the Bhavesh's original request) then there's no need
to construct the UPL (it will happen automagically if the page has
to be faulted in).
What this boils down to, again, is that without more information on
what Bhavesh actually wants to do (i.e. not "there is this call in
Linux"), we're not really able to help him very much. 8)
That is very true indeed! (-:
