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

2202 The kernel memory allocator divides physically contiguous memory
2203 blocks into "zones", where each zone is a power of two number of
2204 pages. This option selects the largest power of two that the kernel
2205 keeps in the memory allocator. If you need to allocate very large
2206 blocks of physically contiguous memory, then you may need to
2207 increase this value.
2208
2209 This config option is actually maximum order plus one. For example,
2210 a value of 11 means that the largest free memory block is 2^10 pages.
2211
2212 The page size is not necessarily 4KB. Keep this in mind
2213 when choosing a value for this option.
