During a subsystem reset the Topology-Change-Report is cleared.
Let's give userland the possibility to clear the MTCR in the case
of a subsystem reset.
To migrate the MTCR, we give userland the possibility to
query the MTCR state.
We indicate KVM support for the CPU topology facility with a new
KVM capability: KVM_CAP_S390_CPU_TOPOLOGY.

Using 222 and moving it a line down might make more sense as 218 is
KVM_CAP_X86_TRIPLE_FAULT_EVENT.
Can you fix this and push both patches to devel?
Also send the fixed patch as a reply to this message so I can pick it
from the list.
next and devel have diverted a bit so I will need to fix this up for
next, same for the Documentation entry which will be 6.39 instead of 6.38.
