here are some coding style fixes.

The following patch remove irq_resource and dma_resource from pci_dev.  It
appears that the serial pci driver depends on irq_resource, however, it may be
broken portions of an old quirk.  I attempted to maintain the existing behavior
while removing irq_resource.  I changed FL_IRQRESOURCE to FL_NOIRQ.  Russell,
could you provide any comments?  irq_resource and dma_resource are most likely
remnants from when pci_dev was shared with pnp.

This fixes some issues in the dvb subsystem and some nasty things in the
v4l saa7146 driver.

[DVB]
 - dvb-core: aquire -> acquire spelling fix
 - nxt600 frontend: don't send zero-byte messages when probing the PLL
   type
 - Kconfig: add a note that says that the CI of the budget-CI card is
   not actually supported by the budget-CI driver
 - ttusb-dec: Check for presence of crc32 function.  Make unknown types
   of packet less likely to cause packet loss.

[V4L]
 - saa7146: use kernel mint_t()/max_t() instead of homebrewn stuff
 - saa7146: disable video clipping before capturing for sure to prevent
   black pictures
 - saa7146: make sure to disable the right video dma upon device close
 - saa7146: don't free resources if disabling an already disabled video
   overlay

This is a simple fix for some of the problems with bad ACPI frequency values:

  Abort if the frequency field in _PSS is zero, as we're having a
  completely broken ACPI table then.

A more complete overhaul of the acpi-cpufreq driver (where the cause of
the problem lies) is in the latest acpi-test tree, but that's definitely
something to be delayed for 2.6.3 -- and the same is true for the
yet-to-be-written do_div64 conversion.

This fixes my APM problems (without them my laptop, Acer TravelMate
210TEV (Celeron 700, 128 MB RAM), hangs after resuming from APM since
2.6.0-test4).

Modified based on comments from Pavel Machek <pavel@suse.cz>, who
has acked the updated patch.

- Replaces pci.ids with a snapshot from pciids.sf.net from 14 Jan 2004

- Changes gen-devlist.c to truncate long device names rather than reject
  the database
- Changes PCI_NAME_SIZE to 96 (and PCI_NAME_HALF to 43) to allow all
  current pci.ids names to fit
- Modifies gen-devlist.c to truncate at 89 characters rather than 79 -
  allows for two digit instance numbers to be added to the name as well
  while staying within the 96 characters allocated. No names in the
  current pci.ids are any longer than this.
- Modifies names.c to no longer limit device name length when displaying
  both vendor and device name; the truncation is done by gen-devlist.c.

This lets the PPC pci hotplug driver initialize single devices, not just
entire slots.

insert missing iounmap()

This is the pending patch that adds 'address' file to show
PCI-address and a few other minor fixes.
As 2.6.0 is out, I'm resending the patch.
Would you mind taking this?

This just gets rid of a stupid compile warning.

James Bottomley found a bug in it; could you also apply:

This is in case others copy this code (which has already happened...)

tg3.c has a bug where it can find the wrong 5704 peer on a machine with
PCI domains.  The problem is that pci_find_slot() can't distinguish
whether it has the correct domain or not.

This patch fixes that problem by introducing pci_get_slot().

This is needed to show pci bus topology to userspace properly.

When plugging a 33MHz card into a bus that's running at 66MHz, I'd like
to see a better error message than:

acpiphp_glue: notify_handler: unknown event type 0x5 for \_SB_.SBA0.PCI4.S2F0

The following patch would give us:

Device \_SB_.SBA0.PCI4.S2F0 cannot be configured due to a frequency mismatch

which I think is clearer.

The functions are not named *_skel_*, so it seems useful not to call them with
this.

Greg,

As discussed about six or so months ago, we agreed to hold off this
patch until fairly late, due to its ability to catch duplicate PCI
driver names.  Please note that I haven't attempted to reproduce the
problem with recent kernels, and that all ARM kernel patches released
since then have had this patch in.

I'm guessing this will actually be 2.6.1 material since it probably
doesn't show for PCI drivers which are part of the kernel tree.


If pci_register_driver fails, the register the PCI driver structure
will not be registered with the driver model.  pci_register_driver
returns with negative value, and we then attempt to unregister the
driver structure.  This leads to an oops in the driver model.

The driver model does not return the number of devices it successfully
bound the driver to, and neither does pci_register_driver() return
this information.

Therefore, all of the code below is redundant.

(There's a little redundancy left in drivers/pci/pci-driver.c but it
is harmless unlike this block.)

This brown paper bag patch is needed to assure cpufreq_update_policy works
correctly.

Please apply, else the next ACPI patch will cause trouble with thermal
