Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc

Pull powerpc updates from Ben Herrenschmidt:
 "This is the powerpc new goodies for 3.17.  The short story:

  The biggest bit is Michael removing all of pre-POWER4 processor
  support from the 64-bit kernel.  POWER3 and rs64.  This gets rid of a
  ton of old cruft that has been bitrotting in a long while.  It was
  broken for quite a few versions already and nobody noticed.  Nobody
  uses those machines anymore.  While at it, he cleaned up a bunch of
  old dusty cabinets, getting rid of a skeletton or two.

  Then, we have some base VFIO support for KVM, which allows assigning
  of PCI devices to KVM guests, support for large 64-bit BARs on
  "powernv" platforms, support for HMI (Hardware Management Interrupts)
  on those same platforms, some sparse-vmemmap improvements (for memory
  hotplug),

  There is the usual batch of Freescale embedded updates (summary in the
  merge commit) and fixes here or there, I think that's it for the
  highlights"

* Freescale on-board CPLD
Some Freescale boards like T1040RDB have an on board CPLD connected.
Required properties:
- compatible: Should be a board-specific string like "fsl,<board>-cpld"
Example:
"fsl,t1040rdb-cpld", "fsl,t1042rdb-cpld", "fsl,t1042rdb_pi-cpld"
- reg: should describe CPLD registers
Example:
cpld@3,0 {
compatible = "fsl,t1040rdb-cpld";
reg = <3 0 0x300>;
};

4) According to sPAPR specification, A Partitionable Endpoint (PE) is an I/O
subtree that can be treated as a unit for the purposes of partitioning and
error recovery. A PE may be a single or multi-function IOA (IO Adapter), a
function of a multi-function IOA, or multiple IOAs (possibly including switch
and bridge structures above the multiple IOAs). PPC64 guests detect PCI errors
and recover from them via EEH RTAS services, which works on the basis of
additional ioctl commands.
