linux-next: manual merge of the akpm-current tree with the pci tree

Hi Andrew,

Today's linux-next merge of the akpm-current tree got a conflict in
include/asm-generic/pgtable.h between commit b766eafe6828 ("PCI: Add
pci_remap_iospace() to map bus I/O resources") from the pci tree and
commit 4cc2f91f2636 ("mm: softdirty: enable write notifications on VMAs
after VM_SOFTDIRTY cleared") from the akpm-current tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
