Juergen Gross 0f88130e8a x86/mm: Fix __swp_entry_to_pte() for Xen PV guests ... Normally __swp_entry_to_pte() is never called with a value translating to a valid PTE. The only known exception is pte_swap_tests(), resulting in a WARN splat in Xen PV guests, as __pte_to_swp_entry() did translate the PFN of the valid PTE to a guest local PFN, while __swp_entry_to_pte() doesn't do the opposite translation. Fix that by using __pte() in __swp_entry_to_pte() instead of open coding the native variant of it. For correctness do the similar conversion for __swp_entry_to_pmd().
