I applied this for the 2.4 ia64 patch.

Marcelo, do we need to do anything else to get this in your tree?

I've applied the 2.6 patch to my trees and will send it on to Linus in a
few days, thanks.

Speaking of PCI... are we gonna have to zap __devinit too? Another
option is to think of add-new-pci-ids-on-the-fly as a CONFIG_HOTPLUG
feature, which should(?) maintain the current __devinit semantics: no
re-probes.

OTOH, __devinit already is a no-op for CONFIG_HOTPLUG cases (read: most
everybody), so I wonder if we care enough about __devinit anymore? I
used the same logic to support __devinitdata removal, after all.

Yeah, that option does break almost all current usages of __devinit* in
pci drivers today with CONFIG_HOTPLUG disabled :(

So either making it a different config option, or just dropping
__devinit* all together is fine with me, one of them needs to happen.

Any preferences from anyone else?

If we drop __devinit* then having CONFIG_HOTPLUG as a config option is
almost pointless as it doesn't really affect much code at all. Any
objections to just always enabling it?

Anyone want to make up any before and after memory usages with
CONFIG_HOTPLUG enabled and disabled to see if it's really as small as
I'm thinking it is?

Do the embedded people care? :)

Actually this doesnt apply cleanly to my tree Bjorn.

Can you please send me an updated patch?

Oops, sorry about that. Here's an updated one. It doesn't include
the agpgart bit because you don't have the latest HP ZX1 gart
code. I'll try to get that merged up soon.

Well, here's some numbers I came up with on 2.6.0-test2 on PPC. I
picked 3 boards, EmbeddedPlanet 8260, IBM Spruce and IBM Walnut, made
the vmlinux (with an occasional fix here and there for other issues),
and came up with the following size changes (see arch/ppc/configs/ for
the base config). From HOTPLUG=n to HOTPLUG=y, and with __devinit stuff
put in it's own section I got:
EmbeddedPlanet 8260 (PPC8260, CONFIG_PCI==n):
.text: +2580
.exit.text: same
.rodata: +104
__ksymtab: same
.data: +352
.init.text (excluding __devinit): same.
.init.dev.text: 1692.
.init.data vs .init.data: 84

IBM Spruce (PPC750):
.text: +18528
.exit.text: -300
.rodata: +956
__ksymstab: +96
.data: +6816
.init.text (excluding __devinit): +132
.init.dev.text: 13032

IBM Walnut (PPC405):
.text: +17648
.exit.text: -300
.rodata: +1288
__ksymstab: +96
.data: +5312
.init.text (excluding __devinit): +128
.init.dev.text: 10508

The 8260 board is almost all 'custom' drivers inside of arch/ppc (long
story) and don't make much use of __init-style markups. The other
boards make use of more standard drivers, and have PCI. Since this is
-test2, and not current BK I'm not sure how correct the .data figures
are now, but it looks like CONFIG_HOTPLUG adds ~13kB to a kernel. So
how about stubbing things out if that makes it easier to code up hotplug
stuff (which can be important on some embedded devices too) so there's
choice?
