1785 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1786 benefit is to increase physical addressing equal to or greater
1787 than 40 bits. Note that this has the side effect of turning on
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.

2197 blocks of physically contiguous memory, then you may need to
2198 increase this value.

2200 This config option is actually maximum order plus one. For example,
2201 a value of 11 means that the largest free memory block is 2^10 pages.

2203 The page size is not necessarily 4KB. Keep this in mind
2204 when choosing a value for this option.
