KVM: s390/mm: new gmap_test_and_clear_dirty function
For live migration kvm needs to test and clear the dirty bit of guest pages.
That for is ptep_test_and_clear_user_dirty, to be sure we are not racing with
other code, we protect the pte. This needs to be done within
the architecture memory management code.
