Re: [PATCH 6/16] define Hit_Invalidate_I to Index_Invalidate_I for loongson2

[Fuxin Zhang <fxzhang@ict.ac.cn>]

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.
The usermanual and datasheet can be downloaded from:
