1721 Choose this option if you want to enable the Enhanced Virtual
1722 Addressing (EVA) on your MIPS32 core (such as proAptiv).
1723 One of its primary benefits is an increase in the maximum size
1724 of lowmem (up to 3GB). If unsure, say 'N' here.

1747 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1748 benefit is to increase physical addressing equal to or greater
1749 than 40 bits. Note that this has the side effect of turning on
1750 64-bit addressing which in turn makes the PTEs 64-bit in size.

1766 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1767 require workarounds. Without workarounds the system may hang
1768 unexpectedly. For more information please refer to the gas
1769 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1770
1771 Loongson 2F03 and later have fixed these issues and no workarounds
1772 are needed. The workarounds have no significant side effect on them
1773 but may decrease the performance of the system so this option should
1774 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1775 systems.

2843 running a MIPS32 system and know that none of your userland binaries
