      KVM: PPC: Added one_reg interface for timer registers · 78accda4
      Bharat Bhushan authored
      If userspace wants to change some specific bits of TSR
      (timer status register) then it uses GET/SET_SREGS ioctl interface.
      So the steps will be:
            i)   user-space will make get ioctl,
            ii)  change TSR in userspace
            iii) then make set ioctl.
      It can happen that TSR gets changed by kernel after step i) and
      before step iii).
      To avoid this we have added below one_reg ioctls for oring and clearing
      specific bits in TSR. This patch adds one registerface for:
           1) setting specific bit in TSR (timer status register)
           2) clearing specific bit in TSR (timer status register)
           3) setting/getting the TCR register. There are cases where we want to only
              change TCR and not TSR. Although we can uses SREGS without
              KVM_SREGS_E_UPDATE_TSR flag but I think one reg is better. I am open
              if someone feels we should use SREGS only here.
           4) getting/setting TSR register

      KVM: PPC: move tsr update in a separate function · d26f22c9
      Bharat Bhushan authored
      This is done so that same function can be called from SREGS and
      ONE_REG interface (follow up patch).

      Merge remote-tracking branch 'upstream/master' into queue · 2ae33b38

      Merge reason:
      From: Alexander Graf <agraf@suse.de>
      "Just recently this really important patch got pulled into Linus' tree for 3.9:
      commit 1674400a
      Author: Anton Blanchard <anton <at> samba.org>
      Date:   Tue Mar 12 01:51:51 2013 +0000
      Without that commit, I can not boot my G5, thus I can't run automated tests on it against my queue.
      Could you please merge kvm/next against linus/master, so that I can base my trees against that?"
