[Pranavkumar Sawargaonkar]

This patchset adds the QEMU side changes for providing PSCI v0.2 to VM.

ChangeLog:

V4:
- Rebase this patch against v11 patchset for in-kernel PSCI v0.2 emulation
 (http://www.spinics.net/lists/kvm-arm/msg09182.html)
- Used PSCI 0.2 DT bindings for linux kernel.
  (http://www.spinics.net/lists/arm-kernel/msg326044.html).

V3:
 - Rebase this patchset against v8 patchset for in-kernel PSCI v0.2 emulation
   (http://www.spinics.net/lists/kvm-arm/msg08780.html)
 - Added common kvm_arm_vcpu_init() function for kvm arm and kvm arm64

V2:
 - Rebase this patchset against v6 patchset for in-kernel PSCI v0.2 emulation
   (http://www.spinics.net/lists/arm-kernel/msg319037.html)
 - Handle KVM_EXIT_SYSTEM_EVENT in kvm-all.c:kvm_cpu_exec()
 - Drop change in kvm_arm_get_host_cpu_features()
 - Improve comments and description of kvm_arch_reset_vcpu() implementation

V1:
 - Initial RFC patchset

Pranavkumar Sawargaonkar (6):
  linux-headers: Update KVM headers from linux-3.16-rc1
  kvm: Handle exit reason KVM_EXIT_SYSTEM_EVENT
  target-arm: Enable KVM_ARM_VCPU_PSCI_0_2 feature when possible
  hw/arm/virt: Use PSCI v0.2 compatible when kernel supports it
  target-arm: Common kvm_arm_vcpu_init() for KVM ARM and KVM ARM64
  target-arm: Implement kvm_arch_reset_vcpu() for KVM ARM64
