If ahd_linux_dev_reset() really can be called with local interrupts disabled

James Bottomley ace4e7185d [SCSI] aic7xxx: fix boot hang with Fujitsu drives
Apparently these are the only drives that try to negotiate IU and QAS
at u160 speeds.  The aic7xxx driver can't cope with this.  The fix is
to eliminate the IU and QAS setting routines.  I've #if 0'd them out,
just in case we ever get the sequencer documentation out of Adaptec,
since we'd then be able to fix the driver.

James Bottomley b1abb4d67f [SCSI] aic7xxx: remove separate target and device allocations
Since the aic driver is now taught to speak in terms of the generic
linux devices, we can now also dispense with the transport class get
routines (since we update the parameters when the driver sees they
change) and also plumb it into the spi transport transfer agreement
reporting infrastructure.

James Bottomley 2bf2c568c8 [SCSI] aic7xxx: fix U160 mode
The new period/dt setting routines don't get the coupling of these
parameters correct.  This means that Domain Validation never gets DT
set, and thus the drive gets restricted to U80.

Fix this by restoring the couplings in the set routines.

James Bottomley c7525233d2 [SCSI] aic7xxx: make correct use of slave_alloc/destroy and remove the per device timer
The allocation of all of our components should be done in slave alloc.
Currently it's rather fancifully refcounted in the queuecommand
callback.  This patch moves allocation and destroy to their correct
places in slave_alloc/slave_destory.  Now we can guarantee that
everywhere a device is requested, it's actually been allocated, so don't
check for this anymore.

Additionally, the per device busy timer was the only source of potential
use after free.  It's been deleted because Linux does the correct thing
with busy returns, so there's no need to implement a separate timer in
the driver.

Finally, implement code that forces all the device parameters to zero
(i.e. async and narrow) in the slave alloc, inform the spi class of the
bios recorded maximums and wait until slave configure before trying
anything more adventurous.

James Bottomley e4e360c325 [SCSI] remove aic7xxx busyq
The aic7xxx driver has two spurious queues in it's linux glue code: the
busyq which queues incoming commands to the driver and the completeq
which queues finished commands before sending them back to the mid-layer

This patch just removes the busyq and makes the aic finally return the
correct status to get the mid-layer to manage its queueing, so a command
is either committed to the sequencer or returned to the midlayer for
requeue.

Additionally, this removes all the aic7xxx driver abuse

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!
