Subject: mm: check the argument of kunmap on architectures without highmem
From: Matthew Wilcox <matthew@wil.cx>

If you're using a non-highmem architecture, passing an argument with the
wrong type to kunmap() doesn't give you a warning because the ifdef
doesn't check the type.

Using a static inline function solves the problem nicely.
