[patch 9/9] Guest page hinting: full s390 support.
...ard a Pr page. The Pz state is replaced by the
Vz state.
For potential volatile pages there is one more pitfall. The transfer of
the hardware dirty bit to the software dirty bit needs to make sure that
the page gets into the stable state before the hardware dirty bit is
cleared. The primitive page_test_and_clear_dirty is split into
page_test_dirty and page_clear_dirty to be able to place a
page_make_stable call between them.
