One more fix was needed, for the intel-quark driver that is only built on 
32-bit configs:

Subject: [PATCH] x86/platform/intel/quark: Explicitly include linux/io.h for virt_to_phys()

Similarly to the previous patches by Sean Christopherson:

 "Through a labyrinthian sequence of includes, usage of virt_to_phys() is
  dependent on the include of asm/io.h in x86's asm/realmode.h, which is
  included in x86's asm/acpi.h and thus by linux/acpi.h.  Explicitly
  include linux/io.h to break the dependency on realmode.h so that a
  future patch can remove the realmode.h include from acpi.h without
  breaking the build."
