Ugh... MintPPC appears to be dead. On KVM with Debian userland (either
jessie or wheezy - no difference in result) booting the commit in
question with your .config oopses as soon as pata_macio is initialized,
due to the bug in "treewide: Move dma_ops from struct dev_archdata into
struct device", and after cherry-picking your own fix for that (commit
46f401c4297a "powerpc/pmac: Fix crash in dma-mapping.h with NULL dma_ops")
the result boots just fine.
Again, that happens both for Debian 8 and Debian 7 userlands, so unless
Mint had been doing something very odd there, I would question the accuracy
of your bisect...
