Kernel Zone Live Reconfiguration for existing CPU pool binding

An administrator can configure a Kernel Zone to use CPUs from an existing resource pool to run its virtual CPUs on. If such a Kernel Zone is booting up, it binds its virtual CPUs to physical CPUs belonging to the processor set of the resource pool. Because the relation between physical and virtual CPUs is established during the boot of the Kernel Zone, subsequent changes to the resource pool may cause that not all physical CPUs are utilized efficiently by the Kernel Zone. To fix this, it was usually necessary to reboot the Kernel Zone. In Oracle Solaris 11.4 SRU57 we improved the Live Zone Reconfiguration to resolve this inefficiency without rebooting the Kernel
