Looking for info on writing 64 bit drivers

Parent article: Linux Device Drivers, Third Edition now online
One topic that I'd really like to see as an addendum, or in LDD4 ;-) is 64 bit compatibility. Either as a new chapter, or distributed through the book.
E.g Cover compat_ioctl vs unlocked_ioctl, DMA, 64/32 compatibility etc.
Does anybody have any pointers to existing online text on this subjecct?
