a9524a76f7 [libata] use dev_printk() throughout drivers
A few drivers were not following the standard meme of printing out
their driver name and version at module load time; this is fixed
as well.

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.

47a8659380 libata: bitmask based pci init functions for one or two ports
This redoes the n_ports logic I proposed before as a bitmask.
ata_pci_init_native_mode is now used with a mask allowing for mixed mode
stuff later on. ata_pci_init_legacy_port is called with port number and
does one port now not two. Instead it is called twice by the ata init
logic which cleans both of them up.

There are stil limits in the original code left over

- IRQ/port mapping for legacy mode should be arch specific values
- You can have one legacy mode IDE adapter per PCI root bridge on some systems
- Doesn't handle mixed mode devices yet (but is now a lot closer to it)

a04ce0ffca [PATCH] PCI/libata INTx cleanup
Simple cleanup to eliminate X copies of the pci_enable_intx() function
in libata.  Moved ahci.c's pci_intx() to pci.c and use it throughout
libata and msi.c.

7da7931283 [PATCH] libata: fix pio_mask values (take 2)
ata_get_mode_mask() uses bits 3 and 4 in the pio_mask to represent PIO
modes 3 and 4.  The value read from the drive, which reports support
for PIO3 and PIO4 in bits 0 and 1, is shifted left by 3 bits and OR'd
with 0x7 (which then corresponds to PIO 2-0 in libata).  Thus, the
drivers below need adjustments to comply with the way pio_mask is
used.  I changed the masks from the commented values to all support
PIO4-0, since the spec mandates that PIO0-2 are supported and there's
no reason not to support PIO3 IMO.

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

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!
