c6e6e666cb [libata] REQUEST SENSE handling fixes
- Move ATAPI check-condition handling out of the timeout handler
- Use multi-qc-issue feature to issue REQUEST SENSE ATAPI PACKET
  command upon receiving an ATAPI check-condition.

This cleans things up a lot, and eliminates a nasty recursion bug.

e533825447 [libata] ata_tf_to_host cleanups
Integrate ata_exec() and ata_tf_to_host() into their only caller,
ata_bus_edd().

Rename ata_tf_to_host_nolock() to ata_tf_to_host().

This makes locking a bit easier to review, and may help pave the way for
future changes.

a7dac447bb [libata] change ata_qc_complete() to take error mask as second arg
The second argument to ata_qc_complete() was being used for two
purposes: communicate the ATA Status register to the completion
function, and indicate an error.  On legacy PCI IDE hardware, the latter
is often implicit in the former.  On more modern hardware, the driver
often completely emulated a Status register value, passing ATA_ERR as an
indication that something went wrong.

Now that previous code changes have eliminated the need to use drv_stat
arg to communicate the ATA Status register value, we can convert it to a
mask of possible error classes.

This will lead to more flexible error handling in the future.

057ace5e79 libata: const-ification bombing run
Enforce access rules where appropriate.

If the compiler is smart enough, this may buy us an optimization or two
as a side effect.

8cbd6df1f0 [PATCH] libata CHS: calculate read/write commands and protocol on the fly (revise #6)
- merge ata_prot_to_cmd() and ata_dev_set_protocol() as
       ata_rwcmd_protocol()
     - pave road for read/write multiple support
     - remove usage of pre-cached command and protocol values and call
       ata_rwcmd_protocol() instead

ae00651020 [libata scsi] improve scsi error handling with ata_scsi_set_sense()
- change "xlat" and "fill" actors in libata-scsi so
    they are responsible for SCSI status and sense data
    when they return 1. This allows GOOD status or a
    specialized error to be set.
  - yield an error for mode sense requests for saved
    values [sat-r06]
  - remove static inlines for ata_bad_scsiop() and
    ata_bad_cdb() which are no longer used

644dd0cc49 [libata] improve device scan
Replace SCSI's legacy "bang at the door" method of probing with one
directly controlled by the underlying ATA transport layer.

We now only call scsi_scan_target() for devices we find, rather than
probing every possible channel/id within a certain range.

1623c81eec [libata] allow ATAPI to be enabled with new atapi_enabled module option
ATAPI is getting close to being ready.  To increase exposure, we enable
the code in the upstream kernel, but default it to off (present
behavior).  Users must pass atapi_enabled=1 as a module option (if
module) or on the kernel command line (if built in) to turn on
discovery of their ATAPI devices.

- changes license of all code from OSL+GPL to plain ole GPL
  - except for NVIDIA, who hasn't yet responded about sata_nv
  - copyright holders were already contacted privately

- adds info in each driver about where hardware/protocol docs may be
  obtained

- where I have made major contributions, updated copyright dates

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!
