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.
