b6782728d7 [PATCH] libata: Add the useful macros/constants needed for merging PATA stuff
HPA presence/enabled
HPA commands

Also add ata_id_is_cfa() as that is needed to detect and handle CF cards
which currently we reject.

3d2ca91095 [PATCH] libata: separate out ata_id_major_version()
Separate out ATA major version calculation from ata_dev_identify()
into ata_id_major_version().  It's preparation for splitting
ata_dev_identify().

9b84754866 [PATCH] Suspend support for libata
This patch adds suspend patch to libata, and ata_piix in particular. For
most low level drivers, they should just need to add the 4 hooks to
work. As I can only test ata_piix, I didn't enable it for more
though.

Suspend support is the single most important feature on a notebook, and
most new notebooks have sata drives. It's quite embarrassing that we
_still_ do not support this. Right now, it's perfectly possible to
suspend the drive in mid-transfer.

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.

c6a33e2464 [PATCH] libata CHS: LBA28/LBA48 optimization (revise #6)
- add lba_28_ok() and lba_48_ok() to ata.h.
     - check ending block number instead of staring block number.
     - use lba_28_ok() for CHS range check
     - LBA28/LBA48 optimization

Suggested by Mark Lord and Alan Cox.

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

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!
