On PCXS chips (PA7000, pa 1.1a), trap #18 is raised on memory faults,
while all later chips (>= PA7100) generate either trap #26, #27 or #28
(depending on the fault type).
Since the current qemu emulation emulates a B160L machine (with a
PA7300LC PCX-L2 chip, we should raise trap #26 (EXCP_DMAR) instead
of #18 (EXCP_DMP) on access faults by the Linux kernel to page zero.
With the patch we now get the correct output (I tested against real

As we have had more than one instance where copy-and-paste of
'check-FOO-y = bar' from a first test under category FOO into
an additional test, which ends up disabling the first (see
commits 992159c7 and 4429532b), it's better to just always use
the form that survives copy-and-paste, even for categories that

Up to now we have relied on the device type to identify a device tree

be instantiable with different compatible strings we introduce the
capability to specialize the node creation depending on actual
compatible value.
NodeCreationPair is renamed into BindingEntry. The struct is enhanced
with compat and match_fn() fields. We introduce a new matching function
adapted to the vfio-platform generic device.
Soon, the AMD XGBE can be instantiated with either manner, i.e.:
-device vfio-amd-xgbe,host=e0900000.xgmac
or using the new option line:

Up to now the vfio-platform device has been abstract and could not be

creating a dummy derived device which only set the compatible string.
Following the few vfio-platform device integrations we have seen the
actual requested adaptation happens on device tree node creation
(sysbus-fdt).
Hence remove the abstract setting, and read the list of compatible
values from sysfs if not set by a derived device.
Update the amd-xgbe and calxeda-xgmac drivers to fill in the number of
compatible values, as there can now be more than one.
Note that sysbus-fdt does not support the instantiation of the
vfio-platform device yet.

In downstream distros like RHEL we'd like to disable some of the "legacy"
devices of QEMU. The ISA version of the Cirrus VGA device is one of these
legacy devices. So let's make the build process a little bit more flexible
here by putting the Cirrus ISA code into a separate file which is only
included if both, CONFIG_VGA_CIRRUS and CONFIG_VGA_ISA are set.
Note that this disables "isa-cirrus-vga" for the ppc-softmmu and the
alpha-softmmu target since CONFIG_VGA_ISA is not set there. But I think
this is OK since these targets are only interested in the PCI variant
anyway.
