for the 'mips' patch, it looks
like the arch maintainer(s) need to fix the PCI DMA support...
No, it's worse than that.
See how non-consistent memory is used by the eepro100 driver
for descriptor bits? The skb->tail bits?
That is very problematic.
What's the problem?
If it isn't allowed to do, then what is the meaning of PCI_DMA_BIDIRECTIONAL
