With CONFIG_DEBUG_SLAB=y I see slab corruption messages during boot on
pSeries machines with IPR adapters with any 2.6.12-rc kernel.

The change which seems to have introduced the problem is "SCSI: revamp
target scanning routines" and may be found at:
http://marc.theaimsgroup.com/?l=bk-commits-head&m=111093946426333&w=2

In order to revert that in a 2.6.12-rc1 tree, I had to revert "target
code updates to support scanned targets" first:
http://marc.theaimsgroup.com/?l=bk-commits-head&m=111094132524649&w=2

With both patches reverted, the corruption messages go away.

I did some digging and the problem seems to be a refcounting issue in
__scsi_add_device.  The target gets freed in scsi_target_reap, and
then __scsi_add_device tries to do another device_put on it.

This patch adds a new driver for "Option" cards.  This is a GSM data card,
controlled by three "serial ports" which are connected via an OHCI adapter,
all located on an oversized PC-Card.  It's sold by several GSM service
providers.

Traditionally, this card has been accessed via the standard serial driver
and appropriate vendor= and product= options.  However, testing has
revealed several problems with this approach, including hung data transfers
and lost data blocks when receiving.

Therefore, I've written a separate driver.

scales to the optimal frequency. The optimal frequency being the lowest
frequency which provides enough power to not trigger the upscaling policy.

A new cpufreq module, based on the ondemand one with my additional patches
just posted.  This one is more suitable for battery environments where its
probably more appealing to have the cpu freq gracefully increase and decrease
rather than flip between the min and max freq's.

N.B. Bruno Ducrot pointed out that the amd64's "do have unacceptable latency
between min and max freq transition, due to the step-by-step requirements
(200MHz IIRC)"; so AMD64 users would probably benefit from this too.

Here is my third attempt at a patch to further update the CompactPCI
hotplug driver infrastructure to address the pci_enable_device issue
discussed on the list as well as a few other issues I discovered during
some more testing.  This version addresses a few more issues pointed out
by Prarit Bhargava.  Changes include:
- cpci_enable_device and its recursive calling of pci_enable_device on
  new devices removed.
- Use list_rwsem to avoid slot status change races between disable_slot
  and check_slots.
- Fixed oopsing in cpci_hp_unregister_bus caused by calling list_del on
  a slot after calling pci_hp_deregister.
- Removed kfree calls in cleanup_slots since release_slot will have
  done it already.
- Reworked init_slots a bit to fix latch and adapter file updating on
  subsequent calls to cpci_hp_start.
- Improved sanity checking in cpci_hp_register_controller.
- Now shut things down correctly in cpci_hotplug_exit.
- Switch to pci_get_slot instead of deprecated pci_find_slot.
- A bunch of CodingStyle fixes.
