1778 benefit is to increase physical addressing equal to or greater

1780 64-bit addressing which in turn makes the PTEs 64-bit in size.

1801 Loongson 2F03 and later have fixed these issues and no workarounds
1802 are needed. The workarounds have no significant side effect on them
1803 but may decrease the performance of the system so this option should
1804 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1805 systems.

2186 The kernel memory allocator divides physically contiguous memory
2187 blocks into "zones", where each zone is a power of two number of
2188 pages. This option selects the largest power of two that the kernel
2189 keeps in the memory allocator. If you need to allocate very large
2190 blocks of physically contiguous memory, then you may need to
2191 increase this value.
2192
2193 This config option is actually maximum order plus one. For example,
2194 a value of 11 means that the largest free memory block is 2^10 pages.
2195
2196 The page size is not necessarily 4KB. Keep this in mind
2197 when choosing a value for this option.
