KVM/ARM New features for 3.17 include:
 - Fixes and code refactoring for stage2 kvm MMU unmap_range
 - Support unmapping IPAs on deleting memslots for arm and arm64
 - Support MMIO mappings in stage2 faults
 - 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)

   higher exception level to prevent execution in an UNKNOWN state.
 
+  For systems with a GICv3 interrupt controller:
+  - If EL3 is present:
+    ICC_SRE_EL3.Enable (bit 3) must be initialiased to 0b1.
+    ICC_SRE_EL3.SRE (bit 0) must be initialised to 0b1.

+    ICC_SRE_EL2.SRE (bit 0) must be initialised to 0b1.

 The requirements described above for CPU mode, caches, MMUs, architected
 timers, coherency and system registers apply to all CPUs.  All CPUs must
 enter the kernel in the same exception level.
