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.

1816 Loongson 2F03 and later have fixed these issues and no workarounds
1817 are needed. The workarounds have no significant side effect on them

2203 The kernel memory allocator divides physically contiguous memory
2204 blocks into "zones", where each zone is a power of two number of
2205 pages. This option selects the largest power of two that the kernel
2206 keeps in the memory allocator. If you need to allocate very large
2207 blocks of physically contiguous memory, then you may need to
2208 increase this value.
2209
2210 This config option is actually maximum order plus one. For example,
2211 a value of 11 means that the largest free memory block is 2^10 pages.
2212
2213 The page size is not necessarily 4KB. Keep this in mind
2214 when choosing a value for this option.
