CONFIG_ACPI_HT_ONLY was a concession to the fact that using ACPI for
processor discovery only was possible already, but in general an
all-or-nothing approach to ACPI is IMHO the safest bet.

So, let's assume in the very near future it becomes possible to compile a
kernel without MPS or $PIR support. Where should those config options go?
These, in addition to pnpbios, are also unneeded with ACPI. That is why I
was advocating the more general "Platform interface options" menu, so we
could have *one* place to config these and ACPI in or out, instead of having
the many different platform interface options in different logical areas.

Oh. OK. Yes. No disagreement there.

One reason is for code cleanliness. Linux's internal data structures for irq
routing and MPS stuff on i386 were not designed to handle the possibility of
multiple ways of getting this info. ACPI init gets in there and does its
thing, but it could be better architected. Making the legacy config options
removable is one way to ensure the kernel has things properly modularized
wrt this, and yes, I think someday (maybe not soon) someone *will* want to
leave out MPS support.

All I can say is using just *part* of ACPI will cause some machine,
somewhere, to not work. I want to avoid scenarios where that happens. If
there are issues with that, can we discuss them asap, perhaps now?

Brad,

This is a tough one because ACPI *is* power management but it is also
configuration. It is equivalent to such things as MPS table parsing, $PIR
parsing, PNPBIOS, as well as APM. The first two don't have CONFIG_ options
at the moment but they should at some point.

The only thing I can think of is a "Platform interface options" menu and
just throw all of the above in that. Any other ideas?

Regards -- Andy

ACPI merge, merges from Dave Jones, IDE updates, stuff from Andrew, PPC64
update, e100[0] driver updates, the works..

And no, I still haven't upgraded my changelog scripts, kill me.
