+Subject: swapops.h: Add #include to fix build failure on powerpc
+
+<linux/swapops.h> uses pte_swp_soft_dirty() and
+pte_swp_clear_soft_dirty(), which are defined by <ams/pgtable.h>.  It
+appears that in most cases it is either indirectly included or has
+previously been included.  However, as of 4.5-rc4 this is not the case
+when building kernel/power/swap.c in a 32-bit powerpc configuration.
