Subject: [Patch v7 0/7] microblaze/PowerPC: Move irq-xilinx to irqchip

Hi,

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-rc5

Thanks,
ZubairLK

V6 -> V7
Rebase to v4.5-rc5
Split print messages cleanup into a separate patch
Use jump label api to restructure read/write handling in driver.

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
