Yep, you are right, only 2 weeks since I looked at that file and
already forgot it.
Ralf, current code (as Maciej tolds), just have _l1 & _l2 variants,
but at least in that file, they are defined to be the same :(
I also vote to unify the mips & mips64 versions of that file, they are
the same :(
Maciej, in the other hand, you didn't coment in the other part, that
we writeback & invalidate when we are asked only to invalidate?
Later, Juan.
