           Summary: SMP Thread CPU Usage Bookkeeping
           Product: RTEMS
           Version: HEAD
          Platform: All
        OS/Version: RTEMS
            Status: NEW
          Severity: enhancement
          Priority: P3
         Component: cpukit
        AssignedTo: joel.sherrill at oarcorp.com
        ReportedBy: joel.sherrill at oarcorp.com

The time of the last context switch is currently kept in a single global
variable.  On a multi-core system, it has to be kept on a per-core basis.  This
patch moves it from thread.h to the per cpu structure.
