[patch] remove weird pmd cast

[Dave Hansen]

I don't know what this is trying to do.  It might be some kind of
artifact from when get_pgd_slow() was removed. 

The expanded expression with __pa() ends up looking something like this:

	(unsigned long)(u64)(u32)pmd-PAGE_OFFSET

and that is just nutty because pmd is a pointer now, anyway.

Attached patch removes the casts.
