Jens Axboe 242f9dcb8b block: unify request timeout handling
Right now SCSI and others do their own command timeout handling.
Move those bits to the block layer.

Instead of having a timer per command, we try to be a bit more clever
and simply have one per-queue. This avoids the overhead of having to
tear down and setup a timer for each command, so it will result in a lot
less timer fiddling.

Jeff Garzik 4c9c8d782c [SCSI] gdth: PCI probe cleanups, prep for PCI hotplug API conversion
- Reduce uses of gdth_pci_str::pdev, preferring a local variable
  (or function arg) 'pdev' instead.

- Reduce uses of gdth_pcistr array, preferring local variable
  (or function arg) 'pcistr' instead.

- Eliminate lone use of gdth_pci_str::irq, using equivalent
  pdev->irq instead

- Eliminate assign-only gdth_pci_str::io_mm

Note:  If the indentation seems weird, that's because a line was
converted from spaces to tabs, when it was modified.

Boaz Harrosh ee54cc6af9 [SCSI] gdth: fix to internal commands execution
The recent patch named:
  [SCSI] gdth: !use_sg cleanup and use of scsi accessors

has done a bad job in handling internal commands issued by gdth_execute().

Internal commands are issued with device gdth_cmd_str ready made directly
to the card, without any mapping or translations of scsi commands. So here
I added a gdth_cmd_str pointer to the gdth_cmndinfo private structure which
is then copied directly to host.

following this patch is a cleanup that removes the home cooked accessors
and reverts them to regular scsi_cmnd accessors. Since they are not used
anymore. After review maybe the 2 patches should be squashed together.

FIXME: There is still a problem with gdth_get_info(). as reported there
   is a WARN_ON trigerd in dma_free_coherent() when doing:
   $ cat /proc/sys/gdth/0

Boaz Harrosh 3892d88ae6 [SCSI] gdth: !use_sg cleanup and use of scsi accessors
gdth_execute() will issue an internal, none scsi-standard commands
onto __gdth_queuecommand(). Since it is not recommended to set
struct scsi_cmnd IO members in llds, gdth now uses internal IO
members for IO. In the case of gdth_execute() these members will be
set properly. In case the command was issued from scsi-ml
(by gdth_queuecommand) they will be set from scsi IO accessors.

  * define gdth IO accessors and use them throughout the driver.
  * use an sg-of-one in gdth_execute() and fix gdth_special_cmd()
    accordingly.
  * Clean the not use_sg code path and company

Boaz Harrosh f842b64e0f [SCSI] gdth: Move members from SCp to gdth_cmndinfo, stage 2
- Cleanup the rest of the scsi_cmnd->SCp members and move them
    to gdth_cmndinfo:
    SCp.this_residual 	 => priority
    SCp.buffers_residual => timeout
    SCp.Status 		 => status and dma_dir
    SCp.Message 	 => info
    SCp.have_data_in 	 => volatile wait_for_completion
    SCp.sent_command 	 => OpCode
    SCp.phase 		 => phase

  - Two more members will be naturally removed in the !use_sg cleanup

  TODO: What is the meaning of gdth_cmndinfo.phase? (rhetorically)

Boaz Harrosh 3058d5de47 [SCSI] gdth: Setup proper per-command private data
- scsi_cmnd and specifically ->SCp of, where heavily abused
    with internal meaning members and flags. So introduce a new
    struct gdth_cmndinfo, put it on ->host_scribble and define a
    gdth_cmnd_priv() accessor to retrieve it from a scsi_cmnd.

  - The structure now holds two members:
    internal_command - replaces the IS_GDTH_INTERNAL_CMD() croft.
    sense_paddr - which was a 64-bit spanning on 2 32-bit members of SCp.
    More overloaded members from SCp and scsi_cmnd will be moved in a later
    patch (For easy review).

  - Split up gdth_queuecommand to an additional internal_function. The later
    is the one called by gdth_execute(). This will be more evident later in
    the scsi accessors patch, but it also facilitates in the differentiation
    between internal_command and external. And the setup of gdth_cmndinfo of
    each command.

* Remove in-source changelog.  It's archived permanently in git and

  * Remove 2.4.x kernel support.  It is an active obstacle to

    gdth_kcompat.h which is 100% redundant in modern kernels.

Linus Torvalds 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!
