1731 Addressing (EVA) on your MIPS32 core (such as proAptiv).
1732 One of its primary benefits is an increase in the maximum size
1733 of lowmem (up to 3GB). If unsure, say 'N' here.

1756 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1757 benefit is to increase physical addressing equal to or greater
1758 than 40 bits. Note that this has the side effect of turning on
1759 64-bit addressing which in turn makes the PTEs 64-bit in size.

1775 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1776 require workarounds. Without workarounds the system may hang
1777 unexpectedly. For more information please refer to the gas
1778 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1779
1780 Loongson 2F03 and later have fixed these issues and no workarounds
1781 are needed. The workarounds have no significant side effect on them
1782 but may decrease the performance of the system so this option should
1783 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1784 systems.

2855 running a MIPS32 system and know that none of your userland binaries
