was a pretty active cycle for KVM.  Changes include:
 
 - a lot of s390 changes: optimizations, support for migration,
   GDB support and more
 
 - ARM changes are pretty small: support for the PSCI 0.2 hypercall
   interface on both the guest and the host (the latter acked by Catalin)
 
 - initial POWER8 and little-endian host support
 
 - support for running u-boot on embedded POWER targets
 
 - pretty large changes to MIPS too, completing the userspace interface
   and improving the handling of virtualized timer hardware
 
 - for x86, a larger set of changes is scheduled for 3.17.  Still,
   we have a few emulator bugfixes and support for running nested
   fully-virtualized Xen guests (para-virtualized Xen guests have
   always worked).  And some optimizations too.
 
 The only missing architecture here is ia64.  It's not a coincidence
 that support for KVM on ia64 is scheduled for removal in 3.17.
