Hi Ingo,

The net effect of the "getting rid of cpumask_t's" will be the same.  This
patch reduces considerably the amount of stack space being required right
now.  The new cpumask_t approach will take quite a bit of time to get it
"up and running".  (It took me about a day to get init/main.c and kernel/sched.c
to just compile... it now needs the temp cpumasks to actually function.  And
there are a number of areas that will need to be altered before functional
testing can start.)

Thanks,
Mike
