The PCI error recovery infrastructure needs to be able to contact all
the drivers affected by a PCI error event, which may mean traversing
all the devices under a given PCI-PCI bridge. This patch adds a
function to the PCI core that traverses all the PCI devices on a PCI
bus and under any PCI-PCI bridges on that bus (and so on), calling a
given function for each device. This provides a way for the error
recovery code to iterate through all devices that are affected by an
error event.
This version is not implemented as a recursive function. Instead,
when we reach a PCI-PCI bridge, we set the pointers to start doing the
devices on the bus under the bridge, and when we reach the end of a
bus's devices, we use the bus->self pointer to go back up to the next
higher bus and continue doing its devices.

These fixes were suggested by pcihpd-discuss, but were dropped in the
initial checkin of the code. These fixes include cleaning up the
hotplug driver sysfs filename, and some minor code cleanups. The driver
also requires at least PROM 4.30, not 4.20.

This patch (as552) fixes yet another small problem recently added. If an
attempt to put a PCI device back into D0 fails because the device doesn't
support PCI PM, it shouldn't count as error. Without this patch the UHCI
controllers on my Intel motherboard don't work.

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.

Some PCI devices (e.g. 3c905B, 3c556B) lose all configuration
(including BARs) when transitioning from D3hot->D0. This leaves such
a device in an inaccessible state. The patch below causes the BARs
to be restored when enabling such a device, so that its driver will
be able to access it.
The patch also adds pci_restore_bars as a new global symbol, and adds a
correpsonding EXPORT_SYMBOL_GPL for that.
Some firmware (e.g. Thinkpad T21) leaves devices in D3hot after a
(re)boot. Most drivers call pci_enable_device very early, so devices
left in D3hot that lose configuration during the D3hot->D0 transition
will be inaccessible to their drivers.
Drivers could be modified to account for this, but it would
be difficult to know which drivers need modification. This is
especially true since often many devices are covered by the same
driver. It likely would be necessary to replicate code across dozens
of drivers.
The patch below should trigger only when transitioning from D3hot->D0
(or at boot), and only for devices that have the "no soft reset" bit
cleared in the PM control register. I believe it is safe to include
this patch as part of the PCI infrastructure.
The cleanest implementation of pci_restore_bars was to call
pci_update_resource. Unfortunately, that does not currently exist
for the sparc64 architecture. The patch below includes a null
implemenation of pci_update_resource for sparc64.
Some have expressed interest in making general use of the the
pci_restore_bars function, so that has been exported to GPL licensed
modules.

For systems with multiple hotplug controllers, you need to use more than
just the slot number to uniquely name the slot. Without a unique slot
name, the pci_hp_register() will fail. This patch adds the bus number

Make PCI fixup data const, so it'll end up in a r/o section.

Instead of adding messy kmalloc_node()s everywhere run the
PCI driver probe on the node local to the device.
This would not have helped for IDE, but should for
other more clean drivers that do more initialization in probe().

on first open (like many network drivers)

Currently rpaphp registers the following bus types as hotplug slots:
1) Actual PCI Hotplug slots
2) Embedded/Internal PCI slots
3) PCI Host Bridges
The second and third bus types are not actually direct parents of
removable adapters. As such, the rpaphp has special case code to fake
results for attributes like power, adapter status, etc. This patch
removes types 2 and 3 from the rpaphp module.
This patch also changes the DLPAR module so that slots can be
DLPAR-added/removed without having been designated as hotplug-capable.

The slot structure in the rpaphp module currently references the PCI
contents of the slot using the PCI device of the parent bridge. This
is unnecessary, since the module is actually interested in the
subordinate bus of the bridge. The dependency on a PCI bridge device
also prohibits the module from registering hotplug slots that have a
root bridge as a parent, since root bridges on PPC64 don't have PCI
devices.
This patch changes struct slot to reference the PCI subsystem using a
pci_bus rather than a pci_dev.

Currently, rpaphp registers Virtual I/O slots as hotplug slots. The
only purpose of this registration is to ensure that the VIO subsystem
is notified of new VIO buses during DLPAR adds. Similarly, rpaphp
notifies the VIO subsystem when a VIO bus is DLPAR-removed. The rpaphp
module has special case code to fake results for attributes like power,
adapter status, etc.
The VIO register/unregister functions could just as easily be made from
the DLPAR module. This patch moves the VIO registration calls to the
DLPAR module, and removes the VIO fluff from rpaphp altogether.

ICH6 spec defines the PORT_ bits as:
PORT_ENABLED (R/W):
0 = Disabled. The port is in the off state and cannot detect any
devices.
1 = Enabled. The port can transition between the on, partial, and
slumber states and can detect devices.
PORT_PRESENT (R/O)
The status of this bit may change at any time. This bit is cleared
when the port is disabled via PORT_ENABLED. This bit is not cleared upon
surprise removal of a device.
So from a textual view it is not necessary that PORT_PRESENT _must_ be set,
especially if a device detection has to be done anyway. And, in fact, this
is the view that ACER has been taken with its new Laptops (e.g. Travelmate
4150).
And the definition of PORT_ENABLED / PORT_PRESENT is mixed up, btw.

When we copy 32bit ->msg_control contents to kernel, we walk the same
userland data twice without sanity checks on the second pass.
Second version of this patch: the original broke with 64-bit arches
running 32-bit-compat-mode executables doing sendmsg() syscalls with
unaligned CMSG data areas
Another thing is that we use kmalloc() to allocate and sock_kfree_s()
to free afterwards; less serious, but also needs fixing.

The acpi-cpufreq driver does a P-state get after a P-state set
to verify whether set went through successfully. This test
is kind of redundant as set goes throught most of the times,
and the test is also expensive as a get of P-states can
take a lot of time (same as a set operation) as it goes
through SMM mode. Effectively, we are doubling the P-state
latency due to this get opertion.
momdule parameter "acpi_pstate_strict" restores orginal paranoia.
