Make available to the user the following task and process performance statistics: * Involuntary Context Switches (task_struct->nivcsw) * Voluntary Context Switches (task_struct->nvcsw) Statistics information is available from: 1. taskstats interface (Documentation/accounting/) 2. /proc/PID/status (task only). This data is useful for detecting hyperactivity patterns between processes.

Fix the length passed while (un)registering cpumask. We were passing sizeof the array, make it strlen(). Error value printed in fatal errors should be derived from the message. The message contains an nlmsgerr embedded with an error value. We must report that value to the user.
