I see it back today in powerpc/merge, thanks.
The issue is it is crashing with HIGHMEM, indeed exactly the same as you saw with "[PATCH] powerpc/8xx: Fix permanently mapped IMMR region.", since that was exactly the same code.
I sent a fix for it, and I also rebased "[PATCH] powerpc/8xx: Fix permanently mapped IMMR region." into v2 to exclude from it the already merged part.
It would be wise if you could merge both.
Thanks Christophe
