Richard Weinberger f09f8dad90 um: Implement a custom pte_same() function ... commit f15b9000eb upstream. UML uses the _PAGE_NEWPAGE flag to mark pages which are not jet installed on the host side using mmap(). pte_same() has to ignore this flag, otherwise unuse_pte_range() is unable to unuse the page because two identical page tables entries with different _PAGE_NEWPAGE flags would not match and swapoff() would never return.
