There is an interesting bug in the vgic code, which manifests itself
when the KVM run loop has a signal pending or needs a vmid generation
rollover after having disabled interrupts but before actually switching
to the guest.
In this case, we flush the vgic as usual, but we
This helps re-factor away some of the repetitive code and makes the code
flow more nicely.

Migrating active interrupts causes the active state to be lost
completely. This implements some additional bitmaps to track the active

This patch implements the static part of the s390 cpu class definitions.
It defines s390 cpu models by means of virtual cpu ids (enum) which contain
information on the cpu generation, the machine class, the GA number and
the machine type. The cpu id is used to instantiate a cpu class per cpu
model.
This patch defines S390 cpu facilities and their presence at the
different cpu model levels. Beside defining a base which facilities
have to be requested per cpu model, these sets are associated to the
defined cpu classes and used to calculate the list of supported
cpu models in context of the curr
This patch provides routines to dynamically update the previously defined
S390 cpu classes in the current host context. The main function performing
this process is s390_setup_cpu_classes(). It takes the current host context
as parameter to setup the classes accordingly. It basically performs the

The patch implements routines to set and retrieve processor configuration
data and to retrieve machine configuration data. The machine related data
