cpuminer-opt maximum support only 64 threads CPU? My CPU threads more than 64, how to use it to be able to fully play

There is nothing in cpuminer-opt to limit threads, maybe resource limitations or a system issue.

stumbled upon this:
"__int128 to support more than 64 CPUs"
https://github.com/holyangel/cpuminer-multi/commit/79785056, even with less than 64 tfe3a54b148f12ca736483777686f4bc3


Good stumble, didn't think of the affinity mask overflowing.

Edit: It looks like this breaks affinity other than default, I don't think 128 bit input works from the cli.
Every affinity I entered turned into -1 even with < 64 threads
