Hey Ralf and others
We seem to be flushing this cache after decompressing the kernel on
mips. Can't we cache this?
If anyone has any advice on how to fix this it would be great:).

I am not sure I fully understand what you mean here. What would we be
caching, instruction, data, both?

One patch that I carried locally and which works for a bunch of
MIPS32r1 compatible platforms out there is this one, I tried to
address some of Ralf's comment as well about the code duplication
(maybe I can get around to resubmit it):

Florian,
You should resubmit this patch as it seems to be correct and fix this issue.
