This patch updates the SLOF version, introducing a number of fixes:
 * add proper graphics support
 * fix bugs with graphical terminal under grub2
 * fix bugs in handling of 64-bit unit addresses
 * fix VSCSI representation to be closer to PowerVM
 * fix bugs which caused grub2 to crash

Functions pci_vga_init() and pci_cirrus_vga_init() are declared
in pc.h. That prevents other platforms (e.g. sPAPR) to use them.

This patch is to create one new file vga-pci.h and move the
declarations to vga-pci.h, so that they can be shared by
all platforms. This patch also cleans up on all platforms.

This reverts commit 518c7fb4. It breaks
new Linux guests with SMP, because IPIs get mapped to large vectors which
our MPIC emulation does not implement.

Conflicts:

Currently for powerpc, kvm_arch_handle_exit() always returns 1, meaning
that its caller - kvm_cpu_exec() - will always exit immediately afterwards
to the loop in qemu_kvm_cpu_thread_fn().

There's no need to do this.  Once we've handled the hypercall there's no
reason we can't go straight around and KVM_RUN again, which is what ret = 0
will signal.  The only exception might be for hypercalls which affect the
state of cpu_can_run(), however the only one that might do this is H_CEDE
and for kvm that is always handled in the kernel, not qemu.

Furtherm setting ret = 0 means that when exit_requested is set from a
hypercall, we will enter KVM_RUN once more with a signal which lets the
the kernel do its internal logic to complete the hypercall with out
actually executing any more guest code.  This is important if our hypercall
also triggered a reset, which previously would re-initialize everything
without completing the hypercall.  This caused the kernel to get confused
because it thought the guest was still in the middle of a hypercall when
it has actually been reset.

This patch therefore changes to ret = 0, which is both a bugfix and a small
optimization.

This gives the kernel a paravirtualized machine to target, without
requiring both sides to pretend to be targeting a specific board
that likely has little to do with the host in KVM scenarios.  This
avoids the need to add new boards to QEMU, just to be able to
run KVM on new CPUs.

Roll the code used to initialize the guest memory space when -R
or -B is used into 'init_guest_space' and then call 'init_guest_space'
from the driver.  This way the reserved guest memory space can
be probed for.  Calling 'mmap' just once as is currently done is not
guaranteed to succeed since the host address space validation might fail.

This command attempts to map to the behavior of -cpu ?.  Unfortunately, the
output of this command differs wildly across targets.

To accommodate this, we use a weak symbol to implement a default version of the
command that fails with a QERR_NOT_SUPPORTED error code.  Targets can then
override and implement this command if it makes sense for them.
