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.

af36d7f0df [libata] license change, other bits
- 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

b8f6153ee4 libata: fix EH locking
Wrap ata_qc_complete() calls in EH context in spinlocks, to prevent
races (mainly in ATAPI code paths).

c138950371 [PATCH] fix atapi_packet_task vs. intr race (take 2)
Interrupts from devices sharing the same IRQ could cause
ata_host_intr to finish commands being processed by atapi_packet_task
if the commands are using ATA_PROT_ATAPI_NODATA or ATA_PROT_ATAPI_DMA
protocol.  This is because libata interrupt handler is unaware that
interrupts are not expected during that period.  This patch adds
ATA_FLAG_NOINTR flag to tell the interrupt handler that we're not
expecting interrupts.

 Note that once proper HSM is implemented for interrupt-driven PIO,
this should be merged into it and this flag will be removed.

 ahci.c is a different kind of beast, so it's left alone.

* The following drivers use ata_qc_issue_prot and ata_interrupt, so
  changes in libata core will do.

  ata_piix sata_sil sata_svw sata_via sata_sis sata_uli

* The following drivers use ata_qc_issue_prot and custom intr handler.
  They need this change to work correctly.

  sata_nv sata_vsc

* The following drivers use custom issue function and intr handler.
  Currently all custom issue functions don't support ATAPI, so this
  change is irrelevant, updated for consistency and to avoid later
  mistakes.

  sata_promise sata_qstor sata_sx4

9309049544 [PATCH] sata_promise: Add PDC40519 id
The Promise TX4200 is a 4-port SATA controller based on the PDC40519 chip. It
meets the description of the 20319, so just a simple ID needs to be added to
support this hardware. Thanks to Martin Povolný for testing.

aa8f0dc6c3 libata: Fix use-after-iounmap
Jens Axboe pointed out that the iounmap() call in libata was occurring
too early, and some drivers (ahci, probably others) were using ioremap'd
memory after it had been unmapped.

The patch should address that problem by way of improving the libata
driver API:

* move ->host_stop() call after all ->port_stop() calls have occurred.

* create default helper function ata_host_stop(), and move iounmap()
call there.

* add ->host_stop_prewalk() hook, use it in sata_qstor.c (hi Mark).
sata_qstor appears to require the host-stop-before-port-stop ordering
that existed prior to applying the attached patch.

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!
