FUJITA Tomonori 67eb63364e [SCSI] aic79xx: fix warnings with CONFIG_PM disabled
CC [M]  drivers/scsi/aic7xxx/aic79xx_osm_pci.o
drivers/scsi/aic7xxx/aic79xx_osm_pci.c:101: warning: 'ahd_linux_pci_dev_suspend' defined but not used
drivers/scsi/aic7xxx/aic79xx_osm_pci.c:121: warning: 'ahd_linux_pci_dev_resume' defined but not used

This moves aic79xx_pci_driver struct, removes some forward
declarations, and adds some ifdef CONFIG_PM.

Hannes Reinecke b5720729f5 [SCSI] aic7xxx: Add suspend/resume support
The aic7xxx driver already contains fragments for suspend/resume
support. So we only need to update them to the current interface
and have full PCI suspend/resume.

Hannes Reinecke f89d0a4e1d [SCSI] aic79xx: remove slave_destroy
Even with the latest fixes aic79xx still occasionally triggers the
BUG_ON in slave_destroy. Rather than trying to figure out the various
levels of interaction here I've decided to remove the callback altogether.

The primary reason for the slave_alloc / slave_destroy is to keep an
index of pointers to the sdevs associated with a given target.
However, by changing the arguments to the affected functions slightly
it's possible to avoid the use of that index entirely.
The only performance penalty we'll incur is in writing the
information for /proc/scsi/XXX, as we'll have to recurse over all
available sdevs to find the correct ones. But I doubt that reading
from /proc is in any way time-critical.

Hannes Reinecke b0d2364887 [SCSI] aic79xx: target hotplug fixes
When a target is added aic79xx tries to be overly clever: it changes
the command on the fly to TEST UNIT READY and tries to requeue the
original command. Sadly this breaks SCSI compability and of course
the midlayer is getting a bit confused by it.

So we're just removing that bit of code and let the midlayer deal with
it. It's clever enough by now. And the driver code is getting simpler.

Hannes Reinecke f41b5cec9b [SCSI] aic79xx bus reset update
As James B. correctly noted, ahd_reset_channel() in
ahd_linux_bus_reset() should be protected by ahd_lock().  However, the
main reason for not doing so was a deadlock with the interesting
polling mechanism to detect the end a bus reset.

This patch replaces the polling mechanism with a saner signalling via
flags; it also gives us the benefit of detecting any multiple calls to
ahd_reset_channel().

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!
