ppc patch queue for 2016-02-01

Currently accumulated patches for target-ppc, pseries machine type and
related devices.
  * Cleanup of error handling code in spapr
  * A number of fixes for Macintosh devices for the benefit of MacOS 9 and X
  * Remove some abuses of the RTAS memory access functions in spapr
  * Fixes for the gdbstub (and monitor debug) for VMX and VSX extensions.
  * Fix pseries machine hotplug memory under TCG
  * Clean up and extend handling of multiple page sizes with 64-bit hash MMUs
  * Fix to the TCG implementation of mcrfs
