Even though we still don't seem to have a client that can actually use this data (something to actually tell the hd to protect itself) I updated the ams code to compile against the latest linux kernel versions. I also fixed a buglet (the interrupt handler should return IRQ_HANDLED even if the init flag isn't set yet since we own the interrupts, they can't be shared). Stelian and all, how about adding this driver to linux? hdaps seems to be there even if it too doesn't serve a useful purpose at this time.
