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

Pull OpenRISC updates from Stafford Horne:
 "I have relocated to London so not much work from me while I get
  settled.

  Still, OpenRISC picked up two patches in this window:

   - Fix for kernel page table walking from Jann Horn

   - MAINTAINER entry cleanup from Palmer Dabbelt"
