Subject: [GIT PULL] Second round of KVM changes for 3.17
Linus,
The following changes since commit 5167d09ffad5b16b574d35ce3047ed34caf1e837:
Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux (2014-08-04 12:31:53 -0700)
are available in the git repository at:

KVM: Move more code under CONFIG_HAVE_KVM_IRQFD (2014-08-06 14:24:47 +0200)
----------------------------------------------------------------
Here are the PPC and ARM changes for KVM, which I separated because
they had small conflicts (respectively within KVM documentation,
and with 3.16-rc changes). Since they were all within the subsystem,
I took care of them.
Stephen Rothwell reported some snags in PPC builds, but they are all
fixed now; the latest linux-next report was clean.
New features for ARM include:
- KVM VGIC v2 emulation on GICv3 hardware
- Big-Endian support for arm/arm64 (guest and host)
- Debug Architecture support for arm64 (arm32 is on Christoffer's todo list)
And for PPC:
- Book3S: Good number of LE host fixes, enable HV on LE
- Book3S HV: Add in-guest debug support
This release drops support for KVM on the PPC440. As a result, the
PPC merge removes more lines than it adds. :)
I also included an x86 change, since Davidlohr tied it to an independent
bug report and the reporter quickly provided a Tested-by; there was no
reason to wait for -rc2.
