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

1787 64-bit addressing which in turn makes the PTEs 64-bit in size.

1808 Loongson 2F03 and later have fixed these issues and no workarounds
1809 are needed. The workarounds have no significant side effect on them
1810 but may decrease the performance of the system so this option should
1811 be disabled unless the kernel is intended to be run on 2F01 or 2F02

2879 32-bit MIPS systems this support is at the cost of increasing the

2881 running a MIPS32 system and know that none of your userland binaries
