mm/gup_test: fix PIN_LONGTERM_TEST_READ with highmem
Patch series "selftests/vm: fix some tests on 32bit".
I finally had the time to run some of the selftests written by me
(especially "cow") on x86 PAE. I found some unexpected "surprises" :)
With these changes, and with [1] on top of mm-unstable, the "cow" tests
and the "ksm_functional_tests" compile and pass as expected (expected
failures with hugetlb in the "cow" tests). "madv_populate" has one
expected test failure -- x86 does not support softdirty tracking.
#1-#3 fix commits with stable commit ids. #4 fixes a test that is not in
mm-stable yet.
A note that there are many other compile errors/warnings when compiling on
32bit and with older Linux headers ... something for another day.

This patch (of 4):
... we have to kmap()/kunmap(), otherwise this won't work as expected
with highmem.
