1729 Addressing (EVA) on your MIPS32 core (such as proAptiv).
1730 One of its primary benefits is an increase in the maximum size

1754 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1755 benefit is to increase physical addressing equal to or greater
1756 than 40 bits. Note that this has the side effect of turning on
1757 64-bit addressing which in turn makes the PTEs 64-bit in size.

1773 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1774 require workarounds. Without workarounds the system may hang
1775 unexpectedly. For more information please refer to the gas
1776 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1777
1778 Loongson 2F03 and later have fixed these issues and no workarounds
1779 are needed. The workarounds have no significant side effect on them
1780 but may decrease the performance of the system so this option should
1781 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1782 systems.

2838 32-bit MIPS systems this support is at the cost of increasing the
2839 size and complexity of the compiled FPU emulator. Thus if you are
2840 running a MIPS32 system and know that none of your userland binaries
