Pull SCSI updates from James Bottomley:
"Usual driver updates (qla2xxx, mpi3mr, mpt3sas, ufs) plus assorted
cleanups and fixes.
The biggest core change is the massive code motion in the sd driver to
remove forward declarations and the most significant change is to
enumify the queuecommand return"

Firmware populates the negotiated SAS link rate in DevicePage0 during
device discovery. Update mpi3mr to cache this value while initializing
the target device.
When available, the cached link rate is used instead of issuing
additional SAS PHY or expander PHY page reads. If the DevicePage0 value
is missing or invalid, the driver falls back to the existing PHY-based
mechanism.

The driver was not reading the MAX_REQ_PER_REPLY_QUEUE_LIMIT IOCFacts
flag, so the reply-queue-full handling was never enabled, even on
firmware that supports it. Reading this flag enables the feature and
prevents reply queue overflow.

Allocate segmented trace buffer if firmware advertises the capability in
IOCfacts.
Upon driver load, read the trace buffer size from driver page 1, calculate
the required segments for trace buffer, and allocate segmented buffers.
Each segment is 4096 bytes in size.
While posting driver diagnostic buffer to firmware, advertise that trace
buffer is segmented.

1-element array with flexible array
Replace the deprecated[1] use of a 1-element array in struct
mpi3_event_data_pcie_topology_change_list with a modern flexible array.
Additionally add __counted_by annotation since port_entry is only ever
accessed in loops controlled by num_entries. For example:
for (i = 0; i < event_data->num_entries; i++) {
handle =
le16_to_cpu(event_data->port_entry[i].attached_dev_handle);

To be able to debug controller problems it is beneficial to allocate and
configure system/host memory buffers which can be used to capture hardware
and firmware diagnostic information.
Add functions required to allocate and post firmware and hardware
diagnostic buffers to the controller and to set up automatic diagnostic
capture triggers.
Captures will be triggered under the following circumstances:
1. Firmware is in FAULT state.
2. Admin commands time out.
3. Controller reset caused due to I/O timeout
