[PATCH] Modpost section mismatch fix

[Raghavendra D Prabhu]

 [Sorry if duplicate, one earlier was corrupt]

Hi,
    I got section mismatches reported by modpost in latest build. It got
    reported for xen_register_pirq and xen_unplug_emulated_devices
    functions. xen_register_pirq makes reference to
    acpi_sci_override_gsi in init.data section; marking
    xen_register_pirq with __init is not feasible since calls are made
    to it from acpi_register_gsi in non-init contexts. So marking it
    __refdata based on assumption that when acpi_sci_override_gsi is
    referenced, it is in  early stages where it is alive.
