Actually, looking again at the paca code, it doesn't seem that
it is dependent upon the kernel NR_CPUS value.
So perhaps all my bitching is much ado about nothing?
Well, I use NR_CPUS as the max value only if I can't find out
"paca" structure length from gdb.
if (!(nr_paca = get_array_length("paca", NULL, 0)))
nr_paca = NR_CPUS;
If we can't figure out "paca" struct size from "gdb", I am sure
there are other things that will break.
