ib_srp: Add post-3.5 upstream patches
The following three patches have been accepted upstream after kernel

ib_srp: Avoid that module removal can trigger a deadlock
Avoid that scsi_remove_host() is invoked from the context of a work
queue thread on which work has been queued that scsi_remove_host()

triggers a deadlock on a pre-2.6.36 kernel. This patch has been

Use the <scsi/srp.h> header from compat-rdma instead of the

Also, undefine pr_fmt() before redefining it since the

cxgb4: Add support for T4 configuration file
This patch adds patch series from linux-next tree to add support for T4
configuration file.
Starting with T4 firmware version 1.3.11.0 the firmware now supports device
configuration via a Firmware Configuration File. The Firmware Configuration
File was primarily developed in order to centralize all of the configuration,
resource allocation, etc. for Unified Wire operation where multiple
Physical / Virtual Function Drivers would be using a T4 adapter simultaneously.
The Firmware Configuration file can live in three locations as shown below
in order of precedence.
1) User defined configuration file: /lib/firmware/cxgb4/t4-config.txt
2) Factory Default configuration file written to FLASH within
the manufacturing process.
3) Hardwired driver configuration.
The meaning of the "Required-Stop" tag is which services must be
available during shutdown of a service. Avoid specifying the same
runlevel for the "Default-Start" and "Default-Stop" tag. Also,
the default start runlevels on Debian are 2, 3, 4 and 5.

dst_neigh_lookup and neigh_release function has been introduced

neigh_release was getting called unnecessary for the kernel < 3.4.0

Fix for ucma context uid=0, causing iWarp RDMA applications to fail in connection establishment.
This is a new patch addressing the librdmacm segfault when RDMA_CM_EVENT_ESTABLISHED event shows up with evt->id_priv = NULL
In the ucma_event_handler(), ctx->file->mut is moved up to prevent race conditions and protect from assigning zero ucma ctx->uid to asynchronously generated events.

linux-next-cherry-picks: Add DB drop recovery patches for Chelsio's T4 adapter
This patch-series implements doorbell drop recovery for Chelsio T4 iWARP driver.
In the event where DBs are dropped application can get stalled for one or more
reasons. So, we recover RDMA and LLD queues in such an event.
We also take care for handling DB overflow events.
The patch-series also has some bug fixes, adds RDMA debugfs stats and removes
kfifo usage for ID mangement.
This patch-series is already merged with linux-next. However it is too big to
go into stable branch. It is required for Chelsio's T4 adapter correctness.
Hence adding them to linux-next-cherry-picks.
