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.
