Dear "Ira W. Snyder",

Would you prefer a patch only for the MPC8349EMDS, or should I try and convert the other boards too? How should I know which boards are safe? Grep for CONFIG_E300?
I think we should try and update all boards where this applies. I'm not sure, but my wild guess is that this means all processors except 40x and 8xx (probably 5xx as well, but AFAICT there is no Linux available for these anyway, so it does not matter).
I think 8xx can be fixed quite easily to do 16 MB if needed. Probably won't be needed though.
Actually, I got a complaint a while ago (I think it was Ben H) about problems with large kernels with debugging options on 8xx.
I see. I think the fix is basically enable pinned TLBs. Then a much bigger area will be mapped. Did they try that?
Don't know if the kernel in question fit in 16 MiB or not... it wasn't a request for assistance, just a "hey, I ran into this, you might want to look at mapping more memory by default" note.
