megaraid's MMIO RD*/WR* macros directly call readl() and writel() with
an 'unsigned long' argument. This throws a warning, but is otherwise OK
because the 'unsigned long' is really the result of ioremap(). This
setup is also OK because the variable can hold an ioremap cookie /or/ a
PCI I/O port (PIO).However, to fix the warning thrown when readl() and writel() are passed
an unsigned long cookie, I introduce 'void __iomem *mmio_base', holding
the same value as 'base'. This will silence the warnings, and also
cause an oops whenever these MMIO-only functions are ever accidentally
passed an I/O address.Signed-off-by: Jeff Garzik

The user-space daemon and tgt kernel module need bi-directional
kernel/user high-performance interface, however, mainline provides no
standard interface like that.This patch adds shared memory interface between kernel and user spaces
like some other drivers do by using own character device. The
user-space daemon and tgt kernel module creates shared memory via mmap
and use it like ring buffer. poll (kernel to user) and write (user to
kernel) system calls are used for notification.Signed-off-by: FUJITA Tomonori

The core scsi target lib functions.
TODO:
- mv md/dm-bio-list.h to linux/bio-list.h so md and us do not have to
do that weird include.
- convert scsi_tgt_cmd's work struct to James's execute code. And try
to kill our scsi_tgt_cmd.
- add host state checking. We do refcouting so hotplug is partially
supported, but we need to add state checking to make it easier on
the LLD.Signed-off-by: Mike Christie

This patch contains the needed changes to the scsi-ml for the target
mode support.Note, per the last review we moved almost all the fields we added
to the scsi_cmnd to our internal data structure which we are going
to try and kill off when we can replace it with support from other
parts of the kernel.The one field we left on was the offset variable. This is needed to handle
the case where the target gets request that is so large that it cannot
execute it in one dma operation. So max_secotors or a segment limit may
limit the size of the transfer. In this case our tgt core code will
break up the command into managable transfers and send them to the
LLD one at a time. The offset is then used to tell the LLD where in
the command we are at. Is there another field on the scsi_cmd for
that?Signed-off-by: Mike Christie

Modify intialization semantics:
- perform basic hardware configuration only (as usual)
- allocate resources
- load and execute firmware- defer link (transport) negotiations to the DPC thread
- again the code in qla2x00_initialize_adapter() to stall probe()
completion was needed for legacy-style scanning.
- DPC thread stalls until probe() complete.- before probe() completes, set DPC flags to perform loop-resync logic
(similar to what's done during cable-insertion/removal).Benefits: user does not have to wait 20+ seconds in case the FC cable
is unplugged during driver load, code consolidation (removal of
redundant link negotiation logic during initialize_adaoter()), and
finilly, the driver no longer needs to defer the fc_remote_port_add()
calls to hold off lun-scanning prior to returning from the probe()
function.Signed-off-by: Andrew Vasquez

If a driver can find its own targets, it can now fill in scan_finished and
(optionally) scan_start in the scsi_host_template. Then, when it calls
scsi_scan_host(), it will be called back (from a thread if asynchronous
discovery is enabled), first to start the scan, and then at intervals to
check if the scan is completed.Also make scsi_prep_async_scan and scsi_finish_async_scan static.

Received from Mark Salyzyn:
Add code to abort outstanding management ioctl fibs when the blinkLED recovery
is performed. This code is 'clunky' and does not have any real feedback in that
the reset could progress before the user application has gotten it's
notification of command completion. We put a schedule() call to delay just the
right amount for most cases, because we tried a spin and still managed to find
cases where we would spin forever waiting for the management application to
acknowledge the impending doom surrounding the cause of the BlinkLED. Will
cause an oops in the context of the management application if we proceed too
quickly. I view this as the lesser of many evils since currently if there are
outstanding management ioctls during a need to reset/recover the adapter, the
management application just locks up and waits forever. The best practices fix
for this problem not going to be simple or easy (at least the fixes I imagine
today); and we found a balance between the needs of the driver to proceed, and
the applications that locked or confused that would hold back the driver. I
just do not like the idea of a kernel oops in an application to deal with low
priority, sluggish or misbehaving applications.Signed-off-by: Mark Haverkamp
