Again. Same issue as before. If you do this then you do a global change
for all architectures. You need to put something in the early boot
sequence (in a non architecture specific way) that sets the first node
online by default.
You have fixed the issue in your earlier patches for the powerpc
archicture. What about the other architectures?
Or did I miss something?
