The max depth of a fastreg mr depends on whether the device supports
DSGL or not. So compute it dynamically based on the device support
and the module use_dsgl option.

There is a race when moving a QP from RTS->CLOSING where a SQ work
request could be posted after the FW receives the RDMA_RI/FINI WR.
The SQ work request will never get processed, and should be completed
with FLUSHED status. Function c4iw_flush_sq(), however was dropping
the oldest SQ work request when in CLOSING or IDLE states, instead of
completing the pending work request. If that oldest pending work
request was actually complete and has a CQE in the CQ, then when that
CQE is proceessed in poll_cq, we'll BUG_ON() due to the inconsistent
SQ/CQ state.
This is a very small timing hole and has only been hit once so far.
The fix is two-fold:
1) c4iw_flush_sq() MUST always flush all non-completed WRs with FLUSHED
status regardless of the QP state.
2) In c4iw_modify_rc_qp(), always set the "in error" bit on the queue
before moving the state out of RTS. This ensures that the state
transition will not happen while another thread is in
post_rc_send(), because set_state() and post_rc_send() both aquire
the qp spinlock. Also, once we transition the state out of RTS,
subsequent calls to post_rc_send() will fail because the "in error"
bit is set. I don't think this fully closes the race where the FW
can get a FINI followed a SQ work request being posted (because
they are posted to differente EQs), but the #1 fix will handle the
issue by flushing the SQ work request.

Some HW platforms can reorder read operations, so we must rmb() after
we see a valid gen bit in a CQE but before we read any other fields
from the CQE.

1) timedout endpoint processing can be starved. If there are continual
CPL messages flowing into the driver, the endpoint timeout
processing can be starved. This condition exposed the other bugs
below.
Solution: In process_work(), call process_timedout_eps() after each CPL
is processed.
2) Connection events can be processed even though the endpoint is on
the timeout list. If the endpoint is scheduled for timeout
processing, then we must ignore MPA Start Requests and Replies.
Solution: Change stop_ep_timer() to return 1 if the ep has already been
queued for timeout processing. All the callers of stop_ep_timer() need
to check this and act accordingly. There are just a few cases where
the caller needs to do something different if stop_ep_timer() returns 1:
1) in process_mpa_reply(), ignore the reply and process_timeout()
will abort the connection.
2) in process_mpa_request, ignore the request and process_timeout()
will abort the connection.
It is ok for callers of stop_ep_timer() to abort the connection since
that will leave the state in ABORTING or DEAD, and process_timeout()
now ignores timeouts when the ep is in these states.
3) Double insertion on the timeout list. Since the endpoint timers
are used for connection setup and teardown, we need to guard
against the possibility that an endpoint is already on the timeout
list. This is a rare condition and only seen under heavy load and
in the presense of the above 2 bugs.
Solution: In ep_timeout(), don't queue the endpoint if it is already on
the queue.

Pull infiniband updates from Roland Dreier:
"Main batch of InfiniBand/RDMA changes for 3.15:
- The biggest change is core API extensions and mlx5 low-level driver
support for handling DIF/DIX-style protection information, and the
addition of PI support to the iSER initiator. Target support will
be arriving shortly through the SCSI target tree.
- A nice simplification to the "umem" memory pinning library now that
we have chained sg lists. Kudos to Yishai Hadas for realizing our
code didn't have to be so crazy.
- Another nice simplification to the sg wrappers used by qib, ipath
and ehca to handle their mapping of memory to adapter.
- The usual batch of fixes to bugs found by static checkers etc.
from intrepid people like Dan Carpenter and Yann Droneaud.
- A large batch of cxgb4, ocrdma, qib driver updates"

Pull bulk of gpio updates from Linus Walleij:
"A pretty big chunk of changes this time, but it has all been on
rotation in linux-next and had some testing. Of course there will be
some amount of fixes on top...
- Merged in a branch of irqchip changes from Thomas Gleixner: we need
to have new callbacks from the irqchip to determine if the GPIO
line will be eligible for IRQs, and this callback must be able to
say "no". After some thinking I got the branch from tglx and have
switched all current users over to use this.
- Based on tglx patches, we have added some generic irqchip helpers
in the gpiolib core. These will help centralize code when GPIO
drivers have simple chained/cascaded IRQs. Drivers will still
define their irqchip vtables, but the gpiolib core will take care
of irqdomain set-up, mapping from local offsets to Linux irqs, and
reserve resources by marking the GPIO lines for IRQs.
- Initially the PL061 and Nomadik GPIO/pin control drivers have been
switched over to use the new gpiochip-to-irqchip infrastructure
with more drivers expected for the next kernel cycle. The
factoring of just two drivers still makes it worth it so it is
already a win.
- A new driver for the Synopsys DesignWare APB GPIO block.
- Modify the DaVinci GPIO driver to be reusable also for the new TI
Keystone architecture.
- A new driver for the LSI ZEVIO SoCs.
- Delete the obsolte tnetv107x driver.
- Some incremental work on GPIO descriptors: have
gpiod_direction_output() use a logical level, respecting assertion
polarity through ACTIVE_LOW flags, adding gpiod_direction_output_raw()
for the case where you want to set that very value. Add
gpiochip_get_desc() to fetch a GPIO descriptor from a specific
offset on a certain chip inside driver code.
- Switch ACPI GPIO code over to using gpiochip_get_desc() and get rid
of gpio_to_desc().
- The ACPI GPIO event handling code has been reworked after
encountering an actual real life implementation.
- Support for ACPI GPIO operation regions.
- Generic GPIO chips can now be assigned labels/names from platform
data.
- We now clamp values returned from GPIO drivers to the boolean [0,1]
range.
- Some improved documentation on how to use the polarity flag was
added.
- a large slew of incremental driver updates and non-critical fixes.
Some targeted for stable"

Add code to check sizes of on-disk data of metadata files such as inode
size, segment usage size, DAT entry size, and checkpoint size. Although
these sizes are read from disk, the current implementation doesn't check
them.
If these sizes are not sane on disk, it can cause out-of-range access to
metadata or memory access overrun on metadata block buffers due to
overflow in sundry calculations.
Both lower limit and upper limit of metadata sizes are verified to
prevent these issues.

With this ioctl the segment usage entries in the SUFILE can be updated
from userspace.
This is useful, because it allows the userspace GC to modify and update
segment usage entries for specific segments, which enables it to avoid
unnecessary write operations.
If a segment needs to be cleaned, but there is no or very little
reclaimable space in it, the cleaning operation basically degrades to a
useless moving operation. In the end the only thing that changes is the
location of the data and a timestamp in the segment usage information.
With this ioctl the GC can skip the cleaning and update the segment
usage entries directly instead.
This is basically a shortcut to cleaning the segment. It is still
necessary to read the segment summary information, but the writing of
the live blocks can be skipped if it's not worth it.

Using platform_get_irq_byname() to retrieve the IRQ number returns the
VIRQ number rather than the local IRQ number for the device. Passing that
value then into regmap_irq_get_virq() causes a failure because the
function is expecting the local IRQ number (e.g. 0, 1, 2, 3, etc).
This patch removes use of regmap_irq_get_virq() to prevent this failure
from happening
