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
