Subject: [GIT PULL] KVM changes for 3.13
Linus,
The following changes since commit 34ec4de42be5006abdd8d0c08b306ffaa64d0d5d:
Merge tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux (2013-10-15 17:14:13 -0700)

kvm, vmx: Fix lazy FPU on nested guest (2013-11-13 18:46:54 +0100)
Not using -rc1 as usual as the base, because the PPC guys based
their 3.13 work on something after -rc4, and decided to do the same
for KVM-PPC. The above commit comes just after -rc5; the backmerge
is commit 13acfd571514 (Powerpc KVM work is based on a commit after rc4).
With all the work going into PPC, there were unfortunately some duplicate
commits, and with them came conflicts. Your tree has already the correct
version of the affected files, except for arch/powerpc/kernel/traps.c
which has bad coding style in your tree and good in ours.
----------------------------------------------------------------
Here are the 3.13 KVM changes. There was a lot of work on the PPC
side: the HV and emulation flavors can now coexist in a single kernel
is probably the most interesting change from a user point of view.
On the x86 side there are nested virtualization improvements and a
few bugfixes. ARM got transparent huge page support, improved
overcommit, and support for big endian guests.
Finally, there is a new interface to connect KVM with VFIO. This
helps with devices that use NoSnoop PCI transactions, letting the
driver in the guest execute WBINVD instructions. This includes
some nVidia cards on Windows, that fail to start without these
patches and the corresponding userspace changes.
