Hi Linus !
This is a simple enough fix that I decided was worth having now, it
basically allow "direct" DMA (non-iommu) to work for devices that have a
< 32-bit DMA mask (such as some infamous broadcom wireless chips) when
the machine simply has not enough memory to go over the chip addressing
limit. This fixes various smallish G5 (like old iMac G5) wireless.
The following changes since commit f4b9a988685da6386d7f9a72df3098bcc3270526:
