This patch adds XICS emulation code (heavily borrowed from QEMU), and wires
this into kvm_cpu__irq() to fire a CPU IRQ via KVM. A device tree entry is
also added. IPIs work, xics_alloc_irqnum() is added to allocate an external
IRQ (which will later be used by the PHB PCI code) and finally, kvm__i
This provides the PCI bridge, definitions for the address layout of the windows
and wires in IRQs. Once PCI devices are all registered, they are enumerated and
DT nodes generated for each.

This patch adds the basic structure for HV calls, their registration and some of
the simpler calls. A similar layout for RTAS calls is also added, again with
some of the simpler RTAS calls used by the guest. The SPAPR RTAS stub is
generated inline. Also, nodes for RTAS are added to the device tr
This is the final piece of the puzzle for PPC SPAPR PCI; this
function splits MMIO accesses into the two PHB windows & directs
things to MMIO/IO emulation as appropriate.

This adds the console code, plus VIO HV terminal nodes are added to
the device tree so the guest kernel will pick it up.

The generated DT is the bare minimum structure required for SPAPR (on which
subsequent patches for VIO, XICS, PCI etc. will build); root node, cpus, memory.
The DT contains CPU-specific configuration; a very simple 'cpu info' mechanism
is added to recognise/differentiate DT entries for POWER7 and
Allocate a page table and point SDR1 to it in order to support the -PR
PPC64 KVM mode. (The alternative, -HV mode, is available only on a small
set of machines.)
This patch also removes the previous dependency on mapping guest RAM with
huge pages; PR KVM doesn't require them so the user isn't for
This series adds support for a PPC64 platform, SPAPR, on top of the previous
more general PPC64 CPU support. This platform is paravirtualised, with most
of the MMU hypercalls being dealt with in the kernel. Userland needs to
describe the environment to the machine with a device tree, cope with so
SPAPR support includes various in-kernel hypercalls, improving performance
by cutting out the exit to userspace. H_BULK_REMOVE is implemented in this
patch.
