New version that switches to the common onstack completion and just a
pointer in the platform_data struct idiom. This gets rid of all the
flags fiddling.

The driver is doing a rather stupid mod_timer allegedly to "give
request sense more time to complete". This is illegal and pointless,
so just eliminate it. Also eliminate all the other uses of struct
timer_list in the driver, which are mostly bogus.

This patch removes almost all inclusions of linux/version.h. The 3
#defines are unused in most of the touched files.
A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.
There are also lots of #ifdef for long obsolete kernels, this was not
touched. In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.
quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'`
search pattern:
/UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h

This patch moves aic7xxx over to the dma_get_required_mask() API and
dumps its open coded memory check.
It also appears from this bug:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=167049
That 39 bit addressing doesn't work on older cards. I surmise that the
AHC_LARGE_SCBS flag is the one that marks cards capable of using 39 bit
addressing, so I also folded that check into the code.

This patch upports all relevant code fixes and bumps the driver version
to 7.0 to signify starting a new tree.

- the eisa layer only probes when it's actually safe, no need for
a driver option
- store the id table directly in linux format instead of convering
at runtime

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.

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.

This should finish the spurious queue removal from aic7xxx (there are
other queues that are probably unnecessary, but at least the major and
obviously unnecessary ones are done with).

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.

Now that we export all the parameters, this is easy to do.
It also means that we can dump about 2000 lines of code that
were dedicated to doing this internally.
Additionally, this removes all the aic7xxx driver abuse
of SCSI timers which were embedded in the DV routines.

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!
