Every time kvm_mmu_get_page() is called with a non-NULL parent_pte argument, link_shadow_page() follows that to set the parent entry so that the new mapping will point to the returned page table. Moving parent_pte handling there allows to clean up the code because parent_pte is passed to kvm_mmu_get_page() just for mark_unsync() and mmu_page_add_parent_pte(). In addition, the patch avoids calling mark_unsync() for other parents in the sp->parent_ptes chain than the newly added parent_pte, because they have been there since before the current page fault handling started.
