This adds the module name to all PCI drivers, if they are built into the
kernel or not. It will show up in /sys/modules/MODULE_NAME/drivers/
It also fixes up the IDE core, which was calling __pci_register_driver()
directly.

This is the driver for the Toshiba TC86C001 GOKU-S PCI IDE controller,
completely reworked from the original brain-damaged Toshiba's 2.4 version.
This single channel UltraDMA/66 controller is very simple in programming,
yet Toshiba managed to plant many interesting bugs in it. The particularly
nasty "limitation 5" (as they call the errata) caused me to abuse the IDE
core in a possibly most interesting way so far. However, this is still
better than the #ifdef mess in drivers/ide/ide-io.c that the original
version included (well, it had much more mess)...

Support for dynamic loading and unloading of ACPI SSDT tables upon slot
hotplugs and unplugs.
On SN platforms, we now represent every populated root bus slot with a single
ACPI SSDT table containing info for every device and PPB attached to the slot.
These SSDTs are generated by the prom at initial boot and hotplug time. The
info in these SSDT tables is used by the SN kernel IO "fixup" code (which is
called at boot and hotplug time).
On hotplugs (i.e. enable_slot()), if running with an ACPI capable prom,
attempt to obtain a new ACPI SSDT table for the slot being hotplugged. If
successful, add the table to the ACPI namespace (acpi_load_table()) and then
walk the new devices and add them to the ACPI infrastructure (acpi_bus_add()).
On hot unplugs (i.e. disable_slot()), if running with an ACPI capable prom,
attempt to remove the SSDT table associated with the slot from the ACPI
namespace (acpi_unload_table_id()) and infastructure (acpi_bus_trim()).
From: John Keller <jpk@sgi.com>
A bug was fixed where the sgi hotplug driver was removing
the slot's SSDT table from the ACPI namespace a bit too early in
disable_slot(). Also, we now call acpi_bus_start() subsequent
to acpi_bus_add().

For all JMicrons except for 361 and 368, AHCI mode enable bits in the
Control(1) should be set. This used to be done in both ahci and
pata_jmicron but while moving programming to PCI quirk, it was removed
from ahci part while still left in pata_jmicron.
The implemented JMicron PCI quirk was incorrect in that it didn't
program AHCI mode enable bits. If pata_jmicron is loaded first and
programs those bits, the ahci ports work; otherwise, ahci device
detection fails miserably.
This patch makes JMicron PCI quirk clear SATA IDE mode bits and set
AHCI mode bits and remove the respective part from pata_jmicron.
Tested on JMB361, 363 and 368.

Fix VIA quirks that were recently broken by Alan Cox in the upstream
kernel (commit 1597cacbe39802d86656d1f2e6329895bd2ef531).
My understanding is that pci_find_present() doesn't work yet at the time
the quirks are run. So I used a two-step quirk as is done for some other
quirks already. First we detect the VIA south bridges and set the right
low and high device limits, then we are ready to actually run the quirks on
the affected devices.

While testing 2.6.20-rc3 on a machine with some CK804 chipsets, we noticed
that quirk_nvidia_ck804_msi_ht_cap() was not detecting HT MSI capabilities
anymore. It is actually caused by the MSI mapping on the root chipset
being the 2nd HT capability in the chain. pci_find_ht_capability() does
not seem to find anything but the first HT cap correctly, because it
forgets to increment the position before looking for the next cap. The
following patch seems to fix it.
At least, this proves that having a ttl is good idea since the machine
would have been stucked in an infinite loop if we didn't have a ttl :)
We have to pass pos + PCI_CAP_LIST_NEXT to __pci_find_next_cap_ttl to
get the next HT cap instead of the same one again.

The sis96x SMBus PCI device depends on two different quirks to run
in a specific order. Apart from being fragile, this was found to
actually break on (at least) recent FC4, FC5, and FC6 kernels. This
patch fixes the quirks so that they work without relying on the
compiler and/or linker to put them in any specific order.

* master.kernel.org:/pub/scm/linux/kernel/git/gregkh/pci-2.6:
[PATCH] PCI: disable PCI_MULTITHREAD_PROBE
|
|
The pci_find_subsys gets called very early by obsolete ide setup parameters.
This is a bogus call since pci is not initialized yet, so the list is empty.
But in the mean time, interrupts get enabled by down_read. This can result in
a kernel panic when the irq controller gets initialized.
This patch checks if the device list is empty before taking the semaphore, and
hence will not enable irq's. Furthermore it will inform that it is called
while pci_devices is empty as a reminder that the ide code needs to be fixed.
The pci_get_subsys can get called in the same manner, and as such is patched
in the same manner.

Linus sayeth:
Google knows everything, and finds, on MS own site no less:
"Windows 2000 default resources:
One 4K memory window
One 2 MB memory window
Two 256-byte I/O windows"
which is clearly utterly bogus and insufficient. But Microsoft apparently
realized this, and:
"Windows XP default resources:
Because one memory window of 4K and one window of 2 MB are not
sufficient for CardBus controllers in many configurations, Windows XP
allocates larger memory windows to CardBus controllers where possible.
However, resource windows are static (that is, the operating system
does not dynamically allocate larger memory windows if new devices
appear.) Under Windows XP, CardBus controllers will be assigned the
following resources:
One 4K memory window, as in Windows 2000
64 MB memory, if that amount of memory is available. If 64 MB is not
available the controller will receive 32 MB; if 32 MB is not available,
the controller will receive 16 MB; if 16 MB is not available, the
bridge will receive 8 MB; and so on down to a minimum assignment of 1
MB in configurations where memory is too constrained for the operating
system to provide a larger window.
Two 256-byte I/O windows"
So I think we have our answer. Windows uses one 4k window, and one 64MB
window. And they are no more dynamic than we are (we _could_ try to do it
dynamically, but let's face it, it's fairly painful to dynamically expand
PCI bus resources - you may need to reprogram everything up to the root,
so it would be absolutely crazy to do that unless you have some serious
masochistic tendencies).
So let's just increase our default value to 64M too.

Since commit 368c73d4f689dae0807d0a2aa74c61fd2b9b075f the kernel will try
to update the non-writeable BAR registers 0..3 of PIIX4 IDE adapters if
pci_assign_unassigned_resources() is used to do full resource assignment of
the bus. This fails because in the PIIX4 these BAR registers have
implicitly assumed values and read back as zero; it used to work because
the kernel used to just write zero to that register the read back value did
match what was written.
The fix is a new resource flag IORESOURCE_PCI_FIXED used to mark a resource
as non-movable. This will also be useful to keep other import system
resources from being moved around - for example system consoles on PCI
busses.

This patch is designed to fix:
- Disk eating corruptor on KT7 after resume from RAM
- VIA IRQ handling
- VIA fixups for bus lockups after resume from RAM
The core of this is to add a table of resume fixups run at resume time.
We need to do this for a variety of boards and features, but particularly
we need to do this to get various critical VIA fixups done on resume.
The second part of the problem is to handle VIA IRQ number rules which
are a bit odd and need special handling for PIC interrupts. Various
patches broke various boxes and while this one may not be perfect
(hopefully it is) it ensures the workaround is applied to the right
devices only.
From: Jean Delvare <khali@linux-fr.org>
Now that PCI quirks are replayed on software resume, we can safely
re-enable the Asus SMBus unhiding quirk even when software suspend support
is enabled.

There are already several places in the kernel that want to search a PCI
device for a given Hypertransport capability. Although this is possible
using pci_find_capability() etc., it makes sense to encapsulate that
logic in a helper - pci_find_ht_capability().
To cater for searching exhaustively for a capability, we also provide
pci_find_next_ht_capability().
We also need to cater for the fact that the HT capability fields may be
either 3 or 5 bits wide. pci_find_ht_capability() deals with this for you,
but callers using the #defines directly must handle that themselves.

The current implementation of __pci_bus_find_cap() does two things,
first it determines the start of the capability chain for the device,
and then it trys to find the requested capability.

a subsequent patch. Externally visible behaviour should be unchanged.

Unfortunately, the .../new_id feature does not work with the 8250_pci
driver.
The reason for this comes down to the way .../new_id is implemented.
When PCI tries to match a driver to a device, it checks the modules
static device ID tables _before_ checking the dynamic new_id tables.
When a driver is capable of matching by ID, and falls back to matching
by class (as 8250_pci does), this makes it absolutely impossible to
specify a board by ID, and as such the correct driver_data value to
use with it.
Let's say you have a serial board with vendor 0x1234 and device 0x5678.
It's class is set to PCI_CLASS_COMMUNICATION_SERIAL.
On boot, this card is matched to the 8250_pci driver, which tries to
probe it because it matched using the class entry. The driver finds
that it is unable to automatically detect the correct settings to use,
so it returns -ENODEV.
You know that the information the driver needs is to match this card
using a device_data value of '7'. So you echo 1234 5678 0 0 0 0 7
into new_id.
The kernel attempts to re-bind 8250_pci to this device. However,
because it scans the PCI driver tables, it _again_ matches the class
entry which has the wrong device_data. It fails.
End of story. You can't support the card without rebuilding the
kernel (or writing a specific PCI probe module to support it.)
So, can we make new_id override the driver-internal PCI ID tables?
IOW, like this:

For node-aware skb allocations we need information about the node in struct
net_device or struct device. Davem suggested to put it into struct device
which this patch does.
In particular:
- struct device gets a new int numa_node member if CONFIG_NUMA is set
- there are two new helpers, dev_to_node and set_dev_node to
transparently deal with the non-numa case
- for pci devices the node-info is set to the value we get from
pcibus_to_node.
Note that for some architectures pcibus_to_node doesn't work yet at the time
we call it currently. This is harmless and will just mean skb allocations
aren't node-local on this architectures until the implementation of
pcibus_to_node on these architectures have been updated (There are patches for
x86 and x86_64 floating around)
