57a62fed87 [PATCH] I2O: Bugfixes to get I2O working again
From: Markus Lidel <Markus.Lidel@shadowconnect.com>

- Fixed locking of struct i2o_exec_wait in Executive-OSM

- Removed LCT Notify in i2o_exec_probe() which caused freeing memory and
  accessing freed memory during first enumeration of I2O devices

- Added missing locking in i2o_exec_lct_notify()

- removed put_device() of I2O controller in i2o_iop_remove() which caused
  the controller structure get freed to early

- Fixed size of mempool in i2o_iop_alloc()

- Fixed access to freed memory in i2o_msg_get()

93d2341c75 [PATCH] mempool: use mempool_create_slab_pool()
Modify well over a dozen mempool users to call mempool_create_slab_pool()
rather than calling mempool_create() with extra arguments, saving about 30
lines of code and increasing readability.

8b3e09e199 [PATCH] I2O: fix and workaround for Motorola/Freescale controller
- This controller violates the I2O spec for the I/O registers.  The patch
  contains a workaround which moves the registers to the proper location.
  (originally author: Matthew Starzewski)

- If a message frame is beyond the mapped address range a error is
  returned.

dcceafe25a [PATCH] I2O: Bugfixes
- Removed some kmalloc's with __GFP_ZERO and replace it with memset()
  because it didn't work properly.

- Fixed returned message frame in i2o_cfg_passthru() which caused raidutils
  to display wrong error message in case a disk was missing.

- Fixed size of printk() in i2o_scsi.c.

- Fixed get_device() and put_device() in probing of the I2O controller.

a1a5ea70a6 [PATCH] I2O: changed I2O API to create I2O messages in kernel memory
Changed the I2O API to create I2O messages first in kernel memory and then
transfer it at once over the PCI bus instead of sending each quad-word over
the PCI bus.

4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

7bd7b09142 [PATCH] I2O: remove i2o_device_class
I2O: cleanup - remove i2o_device_class

I2O devices reside on their own bus so there should be no reason
to also have i2c_device class that mirros i2o bus.

   take care of it
 - Added new device / removed device handling to SCSI-OSM
 - Make status access volatile
 - Cleaned up activation of I2O controller
 - Removed unnecessary wmb() and rmb() calls
 - Use own struct i2o_io for I/O memory instead of struct i2o_dma

b2aaee33fb [PATCH] I2O: Adaptec specific SG_IO access, firmware access through sysfs and 2400A workaround
Changes:
 - Provide SG_IO access to BLOCK and EXECUTIVE class on Adaptec
   controllers
 - Use PRIVATE messages in SCSI-OSM because on some controllers normal
   SCSI class commands like READ or READ CAPACITY cause errors
 - Use new DMA and SG list creation function
 - Added workaround to limit sectors per request for Adaptec 2400A
   controllers

f10378fff6 [PATCH] I2O: new sysfs attributes and Adaptec specific block device access and 64-bit DMA support
Changes:
 - Added Bus-OSM which could be used by user space programs to reset a
   channel on the controller

   controllers

   controllers
 - Added vendor id and product id as sysfs-attribute to Executive classes
 - Added automatic notification of LCT change handling to Exec-OSM
 - Added flushing function to Block-OSM for later barrier implementation
 - Use PRIVATE messages for Block access on Adaptec controllers, which are
   faster then BLOCK class access
 - Cleaned up support for Promise controller
 - New messages are now detected using the IRQ status register as
   suggested by the I2O spec
 - Added i2o_dma_high() and i2o_dma_low() functions
 - Added facility for SG tablesize calculation when using 32-bit and
   64-bit DMA addresses
 - Added i2o_dma_map_single() and i2o_dma_map_sg() which could build the
   SG list for 32-bit as well as 64-bit DMA addresses

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
