Since commit c658b94f6e, MIPS raises
exceptions when accessing invalid memory. This is not the correct
behaviour for MIPS Malta Core LV, as the GT-64120A system controller
just ignore undecoded access. This feature is used by the Linux kernel
to probe for some devices.
Emulate the correct behaviour in QEMU by adding an empty slot covering
the entire memory space decoded by the GT-64120A.

Commit 41cb383f42 made a guest-visible

Fix it by adding the missing compat code.

With the new semantics of pc_sysfw (no -pflash implies "old-style" ROM setup,
-pflash implies "new-style" ROM setup), there is no need anymore for a compat
property. Old machines simply will never use -pflash, and thus will always
use old-style setup.

When vhost device stops, its implementation synchronizes kernel state
back to virtio.c so we can continue emulating the device
in userspace.
This patch ensures that virtio.c's signalled_used_valid flag is reset so
that userspace does not suppress guest notifications due to stale
signalled_used values.

The BIOS that we ship in 1.6 does not use pci info
from host (yet). Several issues turned up
(e.g. around winXP boot crashes). So it's safest to disable that
interface for 1.6 machine types for now, leave it on for 1.7
as we have enough time to fix issues if any.

Now that this code path is not triggered anymore during the tests,
revert commit b332d24a8e. Booting a MIPS

Error **errp argument is not for emitting warnings, it means an error
has occurred and the caller should not make any assumptions about the
state of other return values (unless otherwise documented).
Therefore cpu_x86_create() must unref the new X86CPU itself, and
pc_new_cpu() must check for an Error rather than NULL return value.
While at it, clean up a superfluous NULL check.

pxa2xx_i2c_init() creates a pxa2xx-i2c-slave device on a second i2c-bus,
which has a NULL parent device. This causes an assertion in
object_get_canonical_path() when accessing pxa2xx-i2c-slave's
"parent_bus" link<bus> property in tosa and likely other PXA2xx machines.
Fix this by using the pxa2xx_i2c device, created just before, as parent.

Current hcd-ohci does not handle DMA errors. However they may happen
so here we introduce simple error handling.
On such errors, a typical OHCI will stop operating, signal the guest
about the error by sending "UnrecoverableError Event", set itself into
error state and set "Detected Parity Error" in its PCI config space
to signal that it got an error and so does the patch.
This also adds ohci_die() call to ohci_bus_start() to handle possible
failure of qemu_new_timer_ns().
