1720 Choose this option if you want to enable the Enhanced Virtual
1721 Addressing (EVA) on your MIPS32 core (such as proAptiv).
1722 One of its primary benefits is an increase in the maximum size

1746 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1747 benefit is to increase physical addressing equal to or greater
1748 than 40 bits. Note that this has the side effect of turning on
1749 64-bit addressing which in turn makes the PTEs 64-bit in size.

1765 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1766 require workarounds. Without workarounds the system may hang
1767 unexpectedly. For more information please refer to the gas
1768 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1769
1770 Loongson 2F03 and later have fixed these issues and no workarounds
1771 are needed. The workarounds have no significant side effect on them
1772 but may decrease the performance of the system so this option should
1773 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1774 systems.

2840 32-bit MIPS systems this support is at the cost of increasing the
2841 size and complexity of the compiled FPU emulator. Thus if you are
2842 running a MIPS32 system and know that none of your userland binaries
