Yes, Loongson2 has no Hit_invalidate_I in fact. And although it has
4-way icache, one Index_invalidate_I will invalidate all 4 ways of the
same set.

This #ifdef means Index_Invalidate_I and Hit_Invalidate_I will both be
defined as zero, is that really correct?
(This is the point where I would really like to have a CPU manual ...)
+#else
#define Hit_Invalidate_I 0x10
