mm: check the argument of kunmap on architectures without highmem
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. Reported-by:David Woodhouse <dwmw2@infradead.org> Signed-off-by:
