Hi all,
I have query about usage of range field at pcie@0 under PCIe controller.
Please find snap shot from mpc8536_36.dts..
pci3: pcie@fffe0b000 {
compatible = "fsl,mpc8548-pcie";
device_type = "pci";
#interrupt-cells = <1>;

commit 79f26c268ebad29bd75d078cfc09d3d82b30ccbd (powerpc:
platforms/pseries irq_data conversion) pushed irq_desc down into many
functions, dererencing the descriptor irq field as late as possible.
But it incorrectly passed a linix virtural irq number to RTAS,
resulting in the interrupt not being d

To try to avoid future confusion, rename irq to hwirq when it refers
to a xics domain number instead of a linux irq number.

Hi Ben.
I've submitted the fix for the xics mask real irq I mentioned.
During testing I realized current code is passing rtas a linux irq,
which means no interrupt (at least those above NR_IRQs) is being disabled.
I also created a patch to rename irq to hwirq in xics to try to make
the distiction
