Nope. Not happening. We should just hide CONFIG_XICS just like CONFIG_MPIC, it should be select'ed by the platform (which today is only pseries but that might change). > If we could drop that requirement we could have a single set of names, > ie.

And so we would have the ability to build a kernel that supports in a single binary every platform, as is the case today, ie, pseries, powermac, pa6t, cell, etc... _BUT_ for pseries support, we would have to choose at compile time whether to support old or new machines ? Sounds backward to me :-) > That would avoid all the code that needs a setup_foo_xics() and > setup_foo_mpic() - it'd just be setup_foo(), implemented by either the > XICS or MPIC code. And that would save us what ? one page on a pSeries machine ? yeah !
