Hi Finn,

are there any substantial changes from what I'd tested before? 

The request_region() stuff is new, and I reworked the host->get_lock and 
host->release_lock changes. So you may want to review it again.

Your patch conflicts with (I think) the Mac IDE patches now in Geert's 
tree, and I'd rather avoid hand-patching the lot if at all possible:

m68k_q40_Replace_q40ide_with_pata_falcon_and_falconide
Applying: m68k/q40: Replace q40ide with pata_falcon and falconide

I should have sent these as a two-part series. Sorry about that.
You'll need to apply this patch first:

What's your baseline for this patch?

I've used v5.12 and v5.13-rc5, but mostly I develop on the mac68k branch 
in my github repository.

(In the alternative: just add my Tested-by if nothing changed aside from the
IO region reservation)

I have tested these patches in Aranym (including a multi-platform 
atari/q40 build which required your ISA fix) but I don't have any way to 
test the q40-only code.
