The function mdc_adjust_dirpages is only called on platforms which
don't have pages 4K in size which is why kbuild only reported this
for platforms like the Alpha. The problem was a typo in ordering of
variables in the beginning of a while loop. We were accessing the
dp pointer before it was kmapped.
