Rather than having the job of rewriting this code during 2.6, I'd much
prefer to get something sorted, even if it is ARM only before 2.6.
I believe that there are some common problems with the existing API
which have been hinted at over the last few days, such as large
NR_IRQS. As such, I think it would be a good idea to try to thrash
this issue out and get something which everyone is happy with.
Additionally, I've added Alan's "reserve then hook" idea to the API;
I seem to remember there is a case in IDE which needs something like
this.
You might want to have a look at the powerpc API with it's remaping
capabilities. It's very nice for handling multiple domain spaces. It
might be of some use for you.
I like your proposed API, I think that's where we want to go in the long
run.
Ben.
