Yeah sorry about that, I did the quick fix and havent revisited it yet.

I didnt want to because we have certain firmware workarounds that
involve setting smaller cacheline sizes. I was trying to avoid undoing
that.
As Milton here just pointed out, the generic part of the MWI code only
sets the MWI bit (which we should ignore) so we should be good to do
this. I'll test and send the ppc64 specific fix to akpm.
