425 Loongson-2 is a family of single-core CPUs and Loongson-3 is a
426 family of multi-core CPUs. They are both 64-bit general-purpose
427 MIPS-compatible CPUs. Loongson-2/3 are developed by the Institute
428 of Computing Technology (ICT), Chinese Academy of Sciences (CAS)
429 in the People's Republic of China. The chief architect is Professor
430 Weiwu Hu.

1803 are needed. The workarounds have no significant side effect on them
