Applied patches to Linus' 4.3-rc4 (with none of our recently discussed changes.)
Result missing CPU is back!
I also tried the "cpu_init_udelay=1" with rc5 and that also gave me back the missing CPU? Previously I had tried "cpu_init_udelay=10000" and it did not get missing CPU back (with rc3 or rc4).
I can do more testing if you need it.
Thanks, Don
