1804 Loongson 2F03 and later have fixed these issues and no workarounds
1805 are needed. The workarounds have no significant side effect on them

2191 The kernel memory allocator divides physically contiguous memory
2192 blocks into "zones", where each zone is a power of two number of
2193 pages. This option selects the largest power of two that the kernel
2194 keeps in the memory allocator. If you need to allocate very large
2195 blocks of physically contiguous memory, then you may need to
2196 increase this value.
2197
2198 This config option is actually maximum order plus one. For example,
2199 a value of 11 means that the largest free memory block is 2^10 pages.
2200
2201 The page size is not necessarily 4KB. Keep this in mind
2202 when choosing a value for this option.
