1786 benefit is to increase physical addressing equal to or greater

1788 64-bit addressing which in turn makes the PTEs 64-bit in size.

1804 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1805 require workarounds. Without workarounds the system may hang
1806 unexpectedly. For more information please refer to the gas
1807 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1808
1809 Loongson 2F03 and later have fixed these issues and no workarounds
1810 are needed. The workarounds have no significant side effect on them
1811 but may decrease the performance of the system so this option should
1812 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1813 systems.

2194 The kernel memory allocator divides physically contiguous memory
2195 blocks into "zones", where each zone is a power of two number of
2196 pages. This option selects the largest power of two that the kernel
2197 keeps in the memory allocator. If you need to allocate very large
2198 blocks of physically contiguous memory, then you may need to
2199 increase this value.
2200
2201 This config option is actually maximum order plus one. For example,
2202 a value of 11 means that the largest free memory block is 2^10 pages.
2203
2204 The page size is not necessarily 4KB. Keep this in mind
2205 when choosing a value for this option.
