      [PATCH] I2O: remove on-demand allocation of Scsi_Host's in · b590b47b
      Andrew Morton authored 
      From: Markus Lidel <Markus.Lidel@shadowconnect.com>

- New notification system for i2o_driver's which get now a notification if a
  I2O controller is added or removed.

- SCSI-OSM now uses notifications to create the Scsi_Host to the
  corresponding I2O controller.

- Use __scsi_add_device to preset hostdata.

      [PATCH] I2O: add functionality to scsi_add_device to preset · ff8da0ac
      Andrew Morton authored 
      From: Markus Lidel <Markus.Lidel@shadowconnect.com>

- Add a new function __scsi_add_device, which has an additional parameter
  compared to scsi_add_device.  This parameter is used to preset the hostdata
  pointer.

      i20 rewrite · 3d0affc8
      James Bottomley authored 
      From: Markus Lidel <Markus.Lidel@shadowconnect.com>

generic:
- split i2o_core into several files, grouped by same function
- I2O devices are now registered as devices and show up in sysfs
- the various I2O OSM's (e.g. i2o_scsi) now register in the I2O core
   and also use the 2.6 driver mechanism.
- I2O messages will be created in the message frame instead of creating
   it in local memory and copying it over later on.
- context list for 64 pointer to 32 context conversion now uses a
   double linked list

PCI:
- driver now registers as a PCI device driver and uses probe function to
   get the possible controllers. (needed for hotplugging)
- converted DMA handling from pci_* to generic dma_* functions

Block OSM:
- use one request queue per I2O block device instead of one per
   controller
- I2O block devices and queues are allocated dynamically and therefore
   no more limit of block devices

SCSI OSM:
- corrected bug in SCSI reply function which caused the memory to be
   freed before the done function was called.
- one I2O controller registers as one scsi host instead of one scsi host
   per channel
- no more ch,id,lun => tid mapping table

Config OSM:
- added ioctl32 for passthru and getiops.
- removed ioctl_html

Documentation:
- removed TODO entries from README
- moved docs under Documentation/i2o

      [PATCH] fix for Domain Validation hang on some devices with sym_2 · afe57355
      James Bottomley authored 
      There's a bad hang where the driver locks the system solid trying to do
domain validation with certain devices.  The one I've managed to
reproduce it with is a Quantum Atlas.

What happens is that setting the offset to zero is an async negotiation
message.  However, the driver still seems to have DT set (which is
illegal).  Most devices just reject this as stupid, but the Quantum
seems to try to obey it and hangs the bus.

The simple fix is to reset all PPR options when the offset is set to
zero.

      [PATCH] Allow TCQ depth to be lowered properly · 74a84824
      Brian King authored 
      Ran into a couple small issues with the patch. First,
blk_queue_resize_tags wasn't getting exported, so I sent Jens a patch to
fix this, which he has now sent upstream. Second, the comment above
blk_queue_resize_tags says the queue_lock must be held when calling this
routine. Attached is an updated patch that grabs the lock. Other than
that, it looks good.

      get the kernel to warn about deprecated SCSI ioctls · 59fbf85b
      James Bottomley authored 
      The non unique SCSI ioctls:

SCSI_IOCTL_SEND_COMMAND
SCSI_IOCTL_TEST_UNIT_READY
SCSI_IOCTL_BENCHMARK_COMMAND
SCSI_IOCTL_SYNC
SCSI_IOCTL_START_UNIT
SCSI_IOCTL_STOP_UNIT

Have been deprecated for a while now.  We should make the kernel
complain when a program actually uses one of them, so users have had
adequate warning before they are removed.

      [PATCH] reorder call in scsi_remove_host · 44d90463
      Mike Anderson authored 
      This patch against scsi-misc-2.6 reorders a call to scsi_forget_host in
the scsi_remove_host function. This removes the error message
"Synchronizing SCSI cache..." on rmmod of a scsi host driver module as
shown in example output 1 and 2 below.

I had previous created a much more complicated patch to work around this
problem. In response Christoph mention a simpler solution (pointer to
thread below) which is this patch.
