Merge tag 'for-linus' of github.com:openrisc/linux

Pull OpenRISC updates from Stafford Horne:
 "In this cycle we add PCI support to OpenRISC used in our new QEMU virt
  platform.

  The main updates from me include:

   - Kconfig updates to support OpenRISC PCI (just config now after the
     PCI cleanups I did on Bjorn's branch)

   - A new defconfig for the qemu virt platform.

   - Also there is one MAINTAINERS update. As I was working on the PCI
     series we kept getting bounces from Richard's old email address. I
     added this here; I am not sure how these are usually handled when
     the maintainer doesn't queue it themselves"
