2008-10-10[S390] fix initialization of stpMartin Schwidefsky

2008-10-10[S390] introduce dirty bit for kvm live migrationFlorian Funke
This patch defines a dirty bit in the PGSTE that can be used to implement dirty pages logging for KVM's live migration. The bit is set in the ptep_rcp_copy function, which is called to save dirty and referenced information from the storage key in the PGSTE. The bit can be tested and reset by KVM using the kvm_s390_test_and_clear_page_dirty function that is introduced by this patch.
