  leds: bugfixes for leds-gpio

* master.kernel.org:/pub/scm/linux/kernel/git/gregkh/pci-2.6:
  PCI: Add Kconfig option to disable deprecated pci_find_* API
  PCI: pciserial_resume_one ignored return value of pci_enable_device
  PCI Hotplug: cpqhp_pushbutton_thread(): remove a pointless if() check
  PCI: make pci_match_device() static
  PCI: Remove 3 incorrect MSI quirks.
  PCI: Add MSI INTX_DISABLE quirks for ATI SB700/800 SATA and IXP SB400 USB
  PCI: Add quirk for devices which disable MSI when INTX_DISABLE is set.
  PCI: Add MSI quirk for ServerWorks HT1000 PCIX bridge.
  PCI: Revert "PCI: disable MSI by default on systems with Serverworks HT1000 chips"

Three bugfixes to the leds-gpio driver, plus minor whitespace tweaks:

 - Do the INIT_WORK() before registering each LED, so if its trigger
   becomes immediately active it can schedule work without oopsing..

 - Use normal registration, not platform_driver_probe(), so that
   devices appearing "late" (hotplug type) can still be bound.

 - Mark the driver remove code as "__devexit", preventing oopses
   when the underlying device is removed.

These issues came up when using this driver with some GPIO expanders
living on serial busses, which act unlike "normal" platform devices:
they can appear and vanish along with the serial bus driver.

Now that we have dealt with the real issue, in that some ATI SATA and
USB controllers needed the INTX_DISABLE quirk, we can remove these AMD
chipset global MSI disabling quirks.

This reverts three changesets:

4be8f906 (PCI: disable MSI on RS690)
aea6a433 (PCI: disable MSI on RD580)
f122392f (PCI: disable MSI on RX790)

A reasonably common problem with some devices is that they will
disable MSI generation when the INTX_DISABLE bit is set in the
PCI_COMMAND register.

Quirk this explicitly, guarding the pci_intx() calls in msi.c with
this quirk indication.

The first entries for this quirk are for 5714 and 5780 Tigon3 chips,
and thus we can remove the workaround code from the tg3.c driver.

This is the fix for the following problem:

https://bugzilla.redhat.com/show_bug.cgi?id=227657

The bnx2 device 5706 complains about MSI not working behind a
ServerWorks HT1000 PCIX bridge. An earlier commit to fix the problem:

e3008ded:

"PCI: disable MSI by default on systems with Serverworks HT1000 chips"

was not entirely correct, and has been reverted.

MSI does not work on the PCIX bus because the BIOS did not set the
HT_MSI_FLAGS_ENABLE bit in the HyperTransport MSI capability on the
bridge.  We use the existing quirk_msi_ht_cap() to detect the problem
and disable MSI in all buses behind it.

Fix the memory leak that may occur when we attempt to reuse a cpu_slab
that was allocated while we reenabled interrupts in order to be able to
grow a slab cache.

The per cpu freelist may contain objects and in that situation we may
overwrite the per cpu freelist pointer loosing objects.  This only
occurs if we find that the concurrently allocated slab fits our
allocation needs.

If we simply always deactivate the slab then the freelist will be
properly reintegrated and the memory leak will go away.

The Time of Day clock is the standard time source for s390. It is
- monotonic
- allows very fast reading
- architecture guarantees at least microsecond stepping
- available as part of the architecture

We should announce the rate of tod as 400 to be in sync with the
