1732 Addressing (EVA) on your MIPS32 core (such as proAptiv).

1757 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1758 benefit is to increase physical addressing equal to or greater
1759 than 40 bits. Note that this has the side effect of turning on
1760 64-bit addressing which in turn makes the PTEs 64-bit in size.

1776 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1777 require workarounds. Without workarounds the system may hang
1778 unexpectedly. For more information please refer to the gas
1779 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1780
1781 Loongson 2F03 and later have fixed these issues and no workarounds
1782 are needed. The workarounds have no significant side effect on them
1783 but may decrease the performance of the system so this option should
1784 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1785 systems.

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