The mark_page_dirty() function, despite what its name might suggest, doesn't actually mark the page as dirty as far as the MM subsystem is concerned. It merely sets a bit in KVM's map of dirty pages, if userspace has requested dirty tracking for the relevant memslot. To tell the MM subsystem that the page is dirty, we have to call kvm_set_pfn_dirty() (or an equivalent such as SetPageDirty()). This adds a call to kvm_set_pfn_dirty(), and while we are here, also adds a call to kvm_set_pfn_accessed() to tell the MM subsystem that the page has been accessed. Since we are now using the pfn in several places, this adds a 'pfn' variable to store it and changes the places that used hpaddr >> PAGE_SHIFT to use pfn instead, which is the same thing. This also changes a use of HPTE_R_PP to PP_RXRX. Both are 3, but PP_RXRX is more informative as being the read-only page permission bit setting.
