On Xen kernels, if ATC (address translation cache) is enabled, the
first PCIe DMA read from the adapter fails with an error. This is due to
a bug ASIC, which leads to a failure of 1860 ports to be initialised.
This patch includes the fix to disable Invalidated Tag Match Enable
capability by setting the bit 26 of CHIP_MISC_PRG to 0, by default it is
set to 1.

D-Port is a new port type created with the intention of running link
level diagnostic tests like loopback, traffic test. In static D-port
mode, user configures the port to D-port mode and starts the test, but
in dynamic D-port, once the Brocade switch port is configured to
D-port, it will reject the regular FLOGI from HBA with reason that it is
in D-port mode. So based on the reason code HBA port will turn itself into
D-port and start diagnostic test.

The 'ctl' field of the 'struct ata_taskfile' is not really dual purpose, i.e.
it is not intended for storing the alternate status register (which is mapped
at the same address in the legacy IDE controllers) in the qc_fill_rtf() method.
No other 'libata' driver except 'drivers/scsi/ipr.c' stores the alternate status
register's value in the 'ctl' field of 'qc->result_tf', hence this driver should
not do this as well...

Commit 39c60a0948cc '[SCSI] sd: fix array cache flushing bug causing
performance problems' added temp as a pointer to "temporary " and used
sizeof(temp) - 1 as its length. But sizeof(temp) is the size of the
pointer, not the size of the string constant. Change temp to a static
array so that sizeof() does what was intended.

MegaRAID older Firmware does not support uneven span configuration for PRL11.
E.g User wants to create 34 Driver PRL11 config, it was not possible using old
firmware, since it was not supported configuration in old firmware
Old Firmware expect even number of Drives in each span and same number of
physical drives at each span. Considering above design, 17 Drives at Span-0
and 17 drives at span-1 was not possible.
Now, using this new feature Firmware and Driver both required changes. New
Firmware can allow user to create 16 Drives at span-0 and 18 Drives at
span-1. This will allow user to create 34 Drives Uneven span PRL11.
RAID map is interface between Driver and FW to fetch all required
fields(attributes) for each Virtual Drives. Since legacy RAID map consider
Even Span design, there was no place to keep Uneven span information in
existing Raid map. Because of this limitation, for Uneven span VD, driver can
not use RAID map.
This patch address the changes required in Driver to support Uneven span PRL11
support.
1. Driver will find if Firmware has UnevenSpanSupport or not by reading
Controller Info.
2. If Firmware has UnvenSpan PRL11 support, then Driver will inform about its
capability of handling UnevenSpan PRL11 to the firmware.
3. Driver will update its copy of span info on each time Raid map update is
called.
4. Follow different IO path if it is Uneven Span. (For Uneven Span, Driver
uses Span Set info to find relavent fields for that particular Virtual
Disk)
More verbose prints will be available by setting "SPAN_DEBUG" to 1 at
compilation time.

critical h/w error
Do not return SCSI_MLQUEUE_HOST_BUSY, but send DID_ERROR to SCSI mid-layer, if

Not all disks fill out the VPD pages correctly. Add a blacklist flag
that allows us ignore the SBC-3 VPD pages for a given device. The
BLIST_SKIP_VPD_PAGES flag triggers our existing skip_vpd_pages
scsi_device parameter to bypass VPD scanning.
Also blacklist the offending Seagate drive model.
