This patch sets up some device quirks surrounding arrays to inform the
scsi layer that various mode pages are not supported. This reduces the
severity of the complaints that show up in the logs as the array devices
are enumerated.

Kernel 2.6.16-rc1 broke the ide-scsi driver: ide-scsi loads but fails to
find any devices to bind to.  It also triggers a message "Driver 'ide-scsi'
needs updating - please use bus_type methods" from the driver core.

The IDE core in 2.6.16-rc1 changed the location of an IDE driver's
->probe()/->remove()/->shutdown() methods: they are now in the ide_driver_t
struct not in the gen_driver sub-struct.  drivers/ide/ was updated for this
change but ide-scsi.c wasn't.  Hence the breakage.

This patch repairs ide-scsi and also eliminates the driver core warning.

A critical thing the ServeRAID driver MUST do is hide the physical DASDI
devices from the OS. It does this by intercepting the INQUIRY commands.

In recent 2.6.15 testing, I discovered this to be failing.

The cause was the driver assuming that the INQUIRY response data was in a
simple single buffer, when it was actually a 1 element scatter gather list.

This patch makes ips always look at the correct data when examining an
INQUIRY response.

This patch defines a new template to represent each type of
controllers (identified by the processor used). The template has
members that is set with appropriate values during driver
initialisation. This change is done to support new controllers with
minimal change to existing code. In future, for a new controller
support, a template will be declared and its members initialised
appropriately.

Isolate some PCI config register bitbanging to Intel hardware, as it
should have been all along.

Add support for JMicron JMB360.

When the scsi_execute_async interface was added it ended up reducing
the flexibility of userspace to send arbitrary scsi commands through
sg using SG_IO. The SG_IO interface allows userspace to specify the
CDB length. This is now ignored in scsi_execute_async and it is
guessed using the COMMAND_SIZE macro, which is not always correct,
particularly for vendor specific commands. This patch adds a cmd_len
parameter to the scsi_execute_async interface to allow the caller
to specify the length of the CDB.

Resetting the adapter causes the ServeRAID driver to exceed
the max time allowed by the softlock watchdog. Resetting the
hardware can easily require 30 or more seconds. To avoid the

    "BUG: soft lockup detected on CPU#0!"

result, this patch replaces the mdelay() calls in the
initialization/reset routines with msleep().

A target can LOGO an initiator at any time (i.e. during I/O,
due to a controller hicup, or as a simple authentication
mechanism after an initial CDB command), when this occurs,
the driver attempts to relogin (PLOGI) to the device via the
DPC thread.  Add code to make the appropriate upcall to the
FC transport layer (fc_remote_port_add()) upon successful
completion of the PLOGI.

The driver can typically detect port-loss during an
interrupt context (i.e. via interrogation of a status IOCB's
completion status [CS_PORT_LOGGED_OUT].  Due to the calling
requirements of the fc_rport APIs, the driver would defer
removal of the device to the default workqueue.  If the
work-item was preceded by an event which caused the port to
obtain visibility (relogin successful, target re-logged into
the topology), deferred removal could inadvertently drop the
rport.  The code also no longer defers removal via the
default workqueue, instead opting for use of the driver's
own DPC thread.
