This patch adds : * A byte-based cpumask type(xenctl_cpumask) for setting vcpu-affinity as well as numa-node-affinity, etc in libxc. * Add common bitmap utils to libxc, which can be used both for xenctl_cpumask (and with small changes for xenctl_cpumap, if desired), so that we can do common operations on cpumask easily. As opposed to xenctl_cpumap, xenctl_cpumask is a static structure (just 4 bytes larger for 128 cpus), but keeps the interface/code cleaner. The domctl_interface version keeps the size of xenctl_cpumask consistent between xen and xen-tools. -dulloor
