This patch was inspired by Al Viro, for simplifying and fixing the
retrieval of osd-devices by in-kernel users, eg: file systems.
In-Kernel users, now, go through the same path user-mode does by
opening a file on the osd char-device and though holding a reference
to both the device and the Module.
A file pointer was added to the osd_dev structure which is now
allocated for each user. The internal osd_dev is no longer exposed
outside of the uld. I wanted to do that for a long time so each
libosd user can have his own defaults on the device.
The API is left the same, so user code need not change.
It is no longer needed to open/close a file handle on the osd
char-device from user-mode, before mounting an exofs on it.

For supporting of chained-bios we can not inspect the first
bio only, as before. Caller shall pass the total length of the
request, ie. sum_bytes(bio-chain).
Also since the bio might be a chain we don't set it's direction
on behalf of it's callers. The bio direction should be properly
set prior to this call. So fix a couple of write users that now
need to set the bio direction properly
[In this patch I change both library code and user sites at
exofs, to make it easy on integration. It should be submitted
via James's scsi-misc tree.]

_osd_req_finalize_data_integrity was trying to deduce the number of
out_bytes from passed osd_request->out.bio. This is wrong when
the bio is chained. The caller of _osd_req_finalize_data_integrity
has more ready available information and should just pass it.
Also in the light of future support for CDB-continuation segment this is
a better solution.

single threaded and using the generic MPT_MGMT struct, deleting
mptscsih_TMHandler, replacing with single request TM handler
mptscsih_IssueTaskMgmt, and killing the watchdog timer functions.
2.) cleanup ioc_reset callback handlers, introducing wrappers for

mpt_clear_taskmgmt_in_progress_flag), as the fusion firmware only handles
one task management request at a time

The reason for this change is there is a data corruption when four different
physical memory regions in the 36GB to 37GB region are
accessed. This is only affecting 1078.
The solution is we need to use different addressing when filling in
the scatter gather table for the effected memory regions. So instead
of snooping on all four different memory holes, we treat any physical
addresses in the 36GB address with the same algorithm.
The fix is explained below
1) Ensure that the message frames are NOT located in the trouble
region. There is no remapping available for message frames, they must
be allocated outside the problem region.
2) Ensure that Sense buffers are NOT in the trouble region. There is
no remapping available.
3) Walk through the SGE entries and if any are inside the trouble region
then they need to be remapped as discussed below.
1) Set the Local Address bit in the SGE Flags field.
MPI_SGE_FLAGS_LOCAL_ADDRESS
2) Ensure we are using 64-bit SGEs
3) Set MSb (Bit 63) of the 64-bit address, this will indicate buffer
location is Host Memory.

The CNIC driver controls BNX2 hardware rings and resources used by
iSCSI. Most hardware resources for iSCSI are separate from those
used for ethernet networking.
iSCSI uses a separate MAC address and IP address. The CNIC driver
creates a UIO interface to handle the non-offloaded packets such as
ARP, etc in userspace.

Add support to ibmvscsi for the capabilities MAD. This command gets sent
to the Virtual I/O server prior to login in order to communicate client
capabilities. Additionally it returns information regarding capabilities
that the server supports. The two main capabilities communicated in this
MAD are related to partition migration and client reserve. Client reserve
allows for SCSI-2 reservations to be sent to virtual disks which are backed
by physical LUNs and will result in the reservation being sent to the
physical LUN.

A new mode of error reporting, fast fail, has been added to the VIOS
which allows failover to happen more quickly.
If this new fast fail mode is enabled on the VIOS and the vSCSI client
supports the mode, the VIOS will not return MEDIUM error on path failures,
but rather return VIOSRP_ADAPTER_FAIL in the crq response, which
ibmvscsi will translate to DID_ERROR.
This new mode can be enabled for single path configurations as well,
so it is the new default error reporting mode. A module parameter is
provided to disable this new behavior on the off chance it causes a
problem on some old VIOS version.
