[PATCH 0/1] MR8135: winnt: fix maximum support logical cores

[Herman Semenov (＠GermanAizek)]

2 issues is closed:
- it also fixes spam in logs that maximum value 64 has been exceeded, and (AMD Threadreapers and modern 32 core cpu) have become more accessible
- most software does not use all logical cores by default, and many server boards cannot fully run software
