I could not find the definition of acpi_unregister_gsi in i386/x86_64
code, it is defined only for ia64.

Since it is defined as a weak symbol, I feel it is not getting called
(correct if I am wrong, I searched in google for this).

/* FIXME: implement x86/x86_64 version */
void __attribute__ ((weak)) acpi_unregister_gsi(u32 i)
{
}

How this weak symbols work, is it something like
acpi_pci_irq_disable() will not call acpi_unregister_gsi() in some
platforms.

Thanks
Nobin Mathew.
