Matthew Wilcox 36e235901f PCI: Only build PCI syscalls on architectures that want them
The PCI syscalls are built on every architecture except X86, but only
a few have ever hooked them up.  Use a new Kconfig symbol to save a
couple of kB on the architectures that have never used the syscalls.
Tested on x86 and ia64 only.

Eric W. Biederman 95d77884c7 [PATCH] htirq: tidy up the htirq code
This moves the declarations for the architecture helpers into
include/linux/htirq.h from the generic include/linux/pci.h.  Hopefully this
will make this distinction clearer.

htirq.h is included where it is needed.

The dependency on the msi code is fixed and removed.

The Makefile is tidied up.

Eric W. Biederman 8b955b0ddd [PATCH] Initial generic hypertransport interrupt support
This patch implements two functions ht_create_irq and ht_destroy_irq for
use by drivers.  Several other functions are implemented as helpers for
arch specific irq_chip handlers.

The driver for the card I tested this on isn't yet ready to be merged.
However this code is and hypertransport irqs are in use in a few other
places in the kernel.  Not that any of this will get merged before 2.6.19

Because the ipath-ht400 is slightly out of spec this code will need to be
generalized to work there.

I think all of the powerpc uses are for a plain interrupt controller in a
chipset so support for native hypertransport devices is a little less
interesting.

However I think this is a half way decent model on how to separate arch
specific and generic helper code, and I think this is a functional model of
how to get the architecture dependencies out of the msi code.

Mark Maule fd58e55fcf [PATCH] PCI: msi abstractions and support for altix
Abstract portions of the MSI core for platforms that do not use standard
APIC interrupt controllers.  This is implemented through a new arch-specific
msi setup routine, and a set of msi ops which can be set on a per platform
basis.

David S. Miller 085ae41f66 [PATCH] Make sparc64 use setup-res.c
There were three changes necessary in order to allow
sparc64 to use setup-res.c:

1) Sparc64 roots the PCI I/O and MEM address space using
   parent resources contained in the PCI controller structure.
   I'm actually surprised no other platforms do this, especially
   ones like Alpha and PPC{,64}.  These resources get linked into the
   iomem/ioport tree when PCI controllers are probed.

   So the hierarchy looks like this:

   iomem --|
	   PCI controller 1 MEM space --|
				        device 1
					device 2
					etc.
	   PCI controller 2 MEM space --|
				        ...
   ioport --|
            PCI controller 1 IO space --|
					...
            PCI controller 2 IO space --|
					...

   You get the idea.  The drivers/pci/setup-res.c code allocates
   using plain iomem_space and ioport_space as the root, so that
   wouldn't work with the above setup.

   So I added a pcibios_select_root() that is used to handle this.
   It uses the PCI controller struct's io_space and mem_space on
   sparc64, and io{port,mem}_resource on every other platform to
   keep current behavior.

2) quirk_io_region() is buggy.  It takes in raw BUS view addresses
   and tries to use them as a PCI resource.

   pci_claim_resource() expects the resource to be fully formed when
   it gets called.  The sparc64 implementation would do the translation
   but that's absolutely wrong, because if the same resource gets
   released then re-claimed we'll adjust things twice.

   So I fixed up quirk_io_region() to do the proper pcibios_bus_to_resource()
   conversion before passing it on to pci_claim_resource().

3) I was mistakedly __init'ing the function methods the PCI controller
   drivers provide on sparc64 to implement some parts of these
   routines.  This was, of course, easy to fix.

So we end up with the following, and that nasty SPARC64 makefile
ifdef in drivers/pci/Makefile is finally zapped.

not just those with HOTPLUG.  This avoids the following error on
X86_NUMAQ and x86_64:

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
