1717 Choose this option if you want to enable the Enhanced Virtual
1718 Addressing (EVA) on your MIPS32 core (such as proAptiv).
1719 One of its primary benefits is an increase in the maximum size
1720 of lowmem (up to 3GB). If unsure, say 'N' here.

1742 Choose this option if you want to enable the Extended Physical
1743 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1744 benefit is to increase physical addressing equal to or greater
1745 than 40 bits. Note that this has the side effect of turning on
1746 64-bit addressing which in turn makes the PTEs 64-bit in size.

1762 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1763 require workarounds. Without workarounds the system may hang
1764 unexpectedly. For more information please refer to the gas
1765 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1766
1767 Loongson 2F03 and later have fixed these issues and no workarounds
1768 are needed. The workarounds have no significant side effect on them
1769 but may decrease the performance of the system so this option should
1770 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1771 systems.

2157 a value of 11 means that the largest free memory block is 2^10 pages.

2834 When this is enabled, the kernel will support use of 64-bit floating

2837 32-bit MIPS systems this support is at the cost of increasing the
2838 size and complexity of the compiled FPU emulator. Thus if you are
2839 running a MIPS32 system and know that none of your userland binaries

2841 of your kernel & potentially improve FP emulation performance by
