Description

There is a define which limits the maximum number of fanout CPUs, it is:

#define MRP_NCPUS       128

I think we should change it to
#define MRP_NCPUS       NCPU

Using NCPU won't work - header is included in user land.

We have never hit the limit of 128 fanout CPUs yet anyway, I'll increase to 256 and add an appropriate guard to prevent overflowing any arrays.

It is related to the efforts in #13218
