Brian King 463fc696ed [SCSI] ipr: Use PCI-E reset API for new ipr adapter
Use a newly added PCI API to issue a PCI Fundamental reset
(warm reset) to a new ipr PCI-E adapter. Typically, the
ipr adapter uses the start BIST bit in config space to reset
an adapter. Issuing start BIST on this particular adapter
results in the PCI-E logic on the card losing sync, which
causes PCI-E errors, making the card unusable. The only reset
mechanism that exists on this hardware that does not have this
problem is PCI Fundamental reset (warm reset).

Brian King 65f5647544 [SCSI] ipr: Handle IOA reset request
In ipr dual adapter configurations, the ipr adapter firmware
may require an adapter reset for various reasons. The reset
is requested by the adapter firmware logging an error with
an IOASC of 0x02048000. Add support to log this error, and
reset the adapter.

Brian King 4733804c9f [SCSI] ipr: Fix adapter initialization failure
Since scsi core is always sending scatterlists now, remove
some code which was written with the bad assumption that
a small transfer would not be sent down in a scatterlist.
Without this fix, the ipr driver ends up sending garbage
data to the adapter following a reset, causing it to
fail the reset and take the adapter offline.

brking@us.ibm.com ce155ccecd [SCSI] ipr: Driver initialization fix for kexec/kdump
When kexec booting a kernel when the previous kernel did not
call ipr's shutdown method, the ipr adapter does not get
properly initialized, which can result in the ipr adapter
completing commands issued by the previous kernel. Fix ipr
to detect this scenario by reading the adapter's interrupt
mask register and the microprocessor interrupt register.
If the interrupt mask register indicates that interrupts
are enabled or the reset alert bit is set when the card is
probed, this means the card is in an unknown state and we
hard reset the card.

brking@us.ibm.com ee0a90fa3e [SCSI] ipr: Support new device queueing model
New ipr adapters support a new device queueing model in the
adapter firmware. The queueing model is the NACA queueing model,
but it does not mean use of NACA is required. The new model removes
some of the adapter firmware queue state that made handling QERR=0
almost impossible. The queueing model on older adapters included the
concept of a queue frozen state, which would freeze the response
queue in the adapter when a check condition occurred, requiring a
a primitive to resume the queue. The new queueing model removes this
complexity.

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.
