Tejun Heo d7a80dad2f [PATCH] libata: convert several bmdma-style controllers to new EH, take #3
Convert sata_sis, svw, uli and vsc drivers to new EH.  All the drivers
used to specify ATA_FLAG_SATA_RESET to tell libata to use SATA
hardreset instead of SRST.  This patch makes all the converted drivers
use the standard bmdma error handler which uses both SRST and SATA
hardreset.

All the controllers should be able to perform SRST but still needs
verification.  If some of the controllers can't do SRST, it will be
very easy to spot as it will show up during boot probing.

Alan Cox a6b2c5d475 [PATCH] PATCH: libata. Add ->data_xfer method
We need to pass the device in order to do per device checks such as
32bit I/O enables. With the changes to include dev->ap we now don't have
to add parameters however just clean them up. Also add data_xfer methods
to the existing drivers except ata_piix (which is in the other block of
patches). If you reject the piix one just add a data_xfer to it...

Christoph Hellwig 9227c33de8 [PATCH] move ->eh_strategy_handler to the transport class
Overriding the whole EH code is a per-transport, not per-host thing.
Move ->eh_strategy_handler to the transport class, same as
->eh_timed_out.

Downside is that scsi_host_alloc can't check for the total lack of EH
anymore, but the transition period from old EH where we needed it is
long gone already.

Tejun Heo 30afc84cf7 [SCSI] libata: implement minimal transport template for ->eh_timed_out
SCSI midlayer has moved hostt->eh_timed_out to transport template.  As
libata doesn't need full-blown transport support yet, implement
minimal transport for libata.  No transport class or whatsoever, just
empty transport template with ->eh_timed_out hook.

Alan Cox 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)

Jeff Garzik 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.

Linus Torvalds 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!
