As per the specififcation, the SB_DevFn is the PCI_DEVFN of the target
device and not the source. So PCI_DEVFN(2,0) is not correct. Further the
port ID should be enough to identify devices unless they are MFD. The
SB_DevFn was intended to remove ambiguity in case of these MFD devices.
For non MFD devices the recommendation for the target device IP was to
ignore these fields, but not all of them followed the recommendation.
Some like CCK ignore these fields and hence PCI_DEVFN(2, 0) works and so
does PCI_DEVFN(0, 0) as it works for DPIO. The issue came to light because
of GPIONC which was not getting programmed correctly with PCI_DEVFN(2, 0).
It turned out that this did not follow the recommendation and expected 0
in this field.
In general the recommendation is to use SB_DevFn as PCI_DEVFN(0, 0) for
all devices except target PCI devices.

This patch enables cpu model support in kvm/s390 via the vm attribute
interface.
During KVM initialization, the host properties cpuid, IBC value and the
facility list are stored in the architecture specific cpu model structure.
During vcpu setup, these properties are taken to initialize the related SIE
state. This mechanism allows to adjust the properties from user space and thus
to implement different selectable cpu models.
This patch uses the IBC functionality to block instructions that have not
been implemented at the requested CPU type and GA level compared to the
full host capability.
Userspace has to initialize the cpu model before vcpu creation. A cpu model
change of running vcpus is not possible.
