[PATCH v2 0/6] QEMU ARM64 Migration Fixes

This is an update to the series I posted last week addressing some of
the comments so far.

The main changes to this series are:


  - Save/Restore MP STATE
    - no longer needs CAP_MP_STATE at start
    - re-uses cpu->powered_off for storing state (no stream ABI change)
    - kvm_enabled() runtime check (although ioctl still in #if defined)
  - Save/Restore SPSR
    - use the correct bank_number for aarch32
    - only tweak SPSR for elevated exception levels
  - arm_giv_kvm
    - add Christoffer's Acked-by:

The only question up in the air at the moment is defining a new
constant for the MP_STATE to represent powered off which I'm going to
look at when I re-spin the kernel series.
