Patch: fix wrong HD activity control by ahci driver
The ahci driver 1.0 sets the SActive bit on every transaction,
causing the LED to light up. The SActive bit is used only for
native command queuing (NCQ) which the current driver version
doesn't implement. Resetting the SActive bit is the device's
responsibility (by sending a "Set Device Bits FIS" to the
host adapter) but this is not required in response to
non-NCQ commands, and (most) devices don't. Thus the LED
stays always on. This patch fixes the LED behavior.

Hello,
This patch adds the Intel ICH7-M DH DID to the ahci.c file for AHCI mode SATA support. This patch was built against the 2.6.13-rc6 kernel.
If acceptable, please apply.
Thanks,
Jason Gaston

The previous patch did not compile cleanly on all architectures so
here's a fixed one which #includes <linux/dma-mapping.h>.
Use the DMA_{64,32}BIT_MASK constants from dma-mapping.h when calling
pci_set_dma_mask() or pci_set_consistent_dma_mask()
This patch includes dma-mapping.h explicitly because it caused errors
on some architectures otherwise.

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.
This patch adds the Intel ESB2 DID's to the ahci.c file for AHCI mode SATA
support.

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!
