[PATCH v3 0/3] nVMX: Fixes to run Xen as L1

[Bandan Das]

Minor changes to enable Xen as a L1 hypervisor.

Tested with a Haswell host, Xen-4.3 L1 and debian6 L2

v3:
* Add WARN_ON in nested_vmx_exit
* Rebase on top of 3.15-rc1
* Also noticed a new behavior which I think is related to 
  commit 36be0b9deb23161e KVM: x86: Add nested virtualization support for MPX
  On running L2, console gets filled up with - 
  vmwrite error: reg 2812 value 0 (err 12) ..
  I will post a separate patch to get feedback, since these three
  patches have probably addressed all of reviewers' concerns

v2: 
* Remove advertising single context invalidation for emulated invept
  Patch "KVM: nVMX: check for null vmcs12 when L1 does invept" from v1 
  is now obsolete and is removed
* Reorder patches "KVM: nVMX: Advertise support for interrupt acknowledgement"
  and "nVMX: Ack and write vector info to intr_info if L1 asks us to"
* Add commit description to 2/3 and change comment for nested_exit_intr_ack_set

Jan, I will send a separate unit-test patch
