[Patch V6 0/6] microblaze/PowerPC: Move irq-xilinx

[Zubair Lutfullah Kakakhel]

Hi,

The MIPS based Xilfpga platform uses the Xilinx interrupt controller
daisy chained to the MIPS microAptiv cpu interrupt controller.

This patch series moves the Xilinx interrupt controller driver out
of arch/microblaze to drivers/irqchip and then cleans it up a bit.
And then removes another implementation of the driver in arch/powerpc.

This effort results in one common driver usable by mips,microblaze
and powerpc.

Compile tested on microblaze-el.
Tested using qemu-system-ppc using virtix440-ml507
Tested on MIPSfpga platform.

Based on v4.9-rc3

Thanks,
ZubairLK

V5 -> V6
Split patch series. Patches for arch/mips can go separately
Rebase to v4.9-rc3
Added chained_irq_enter/exit
Removed __func__ used in pr_err

V4 -> V5
Added a new patch that removes the PPC driver
Rebase to v4.9-rc1
Better error handling

V3 -> V4
Better error handling
Some minor fixups

V2 -> V3
Cleanup the interrupt controller driver a bit based on feedback
Rebase to v4.8-rc4

V1 -> V2
Resubmitting without truncating the diff output for file moves
Removed accidental local mac address entry
Individual logs have more detail
