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

* so on. But be warned, it's an ABSOLUTE REQUIREMENT ! This is needed mainly
