Doug Ledford and Red Hat reported a crash when running the rdma_cm on
a real-time OS. The crash has the following call trace:

rdma_destroy_id
cma_exch
cma_cancel_operation
rdma_node_get_transport
rt_mutex_slowunlock
bad_area_nosemaphore
oops_enter
They were able to reproduce the crash multiple times with the
following details:
Crash seems to always happen on the:
mutex_unlock(&conn_id->handler_mutex);
as conn_id looks to have been freed during this code path.
An examination of the code shows that a race exists in the request
handlers. When a new connection request is received, the rdma_cm
allocates a new connection identifier. This identifier has a single
reference count on it. If a user calls rdma_destroy_id() from another
thread after receiving a callback, rdma_destroy_id will proceed to
destroy the id and free the associated memory. However, the request
handlers may still be in the process of running. When control returns
to the request handlers, they can attempt to access the newly created
identifiers.
Fix this by holding a reference on the newly created rdma_cm_id until
the request handler is through accessing it.

Improve the status messages that are displayed during some operations of the
PowerPC watchdog timer driver. When the watchdog is enabled, the timeout is
displayed as a number of seconds, instead of an obscure "period". The "period"
is the position of a bit in a 64-bit timer register. The higher the value,
the quicker the watchdog timeout occurs. Some people chose a high "period"
value for the timer and get confused as to why the board resets within a
few seconds.
Messages displayed during open and close are now debug messages, so that they
don't clutter the console by default. Finally, printk() is replaced with the
pr_xxx() equivalent.

This submission includes:
- Fix to intel_scu_write() to start watchdog timer the on the
first write, and refresh on subsequent writes.
This enables Open, write, write, ... usage model.
- Moves boot parameter checks from intel_scu_open() to
intel_scu_watchdog_init(), so driver init will fail if these
parameters are out of bounds.
- Adds check for whether process waiting in wait_event_interruptible()
received a signal while it was waiting.
- Other small error handling changes.
Removed the read() method for now as that wass a non-standard behaviour.

TI's sequencer serial port (TI-SSP) is a jack-of-all-trades type of serial port
device. It has a built-in programmable execution engine that can be programmed
to operate as almost any serial bus (I2C, SPI, EasyScale, and others).
This patch adds a driver for this controller device. The driver does not
expose a user-land interface. Protocol drivers built on top of this layer are
expected to remain in-kernel.

dsi_vc_send_bta_sync() waits for BTA interrupt with a 500ms timeout. If
a DSI error happens, no BTA is received and the timeout triggers. This
could be handled much faster by listening to DSI errors also.
This patch uses the ISR support to notice DSI errors while waiting for
the BTA, thus speeding up the fail-path considerably.

The structures dss_reg_field and dss_clk_source_name have enum members which
specify the register field and the clock source respectively. These members are
not used to choose the correct result in the corresponding feature functions.
Remove these members and change the features array declaration to incorporate
these enums.
The structure dss_clk_source_name without the enum member is just a pointer to
an string. Remove the structure and use a character pointer directly.

Note that this patch also makes 2 changes to the code paths for the f71889fg
to keep the code unified between the 2 (for simplicities sake). Both of these
are harmless for then f71889fg:
1) The first change is to always set the FAN_PROG_SEL bit to 0. This influences
accesses to some banked fan / pwm registers. On the f71889fg no registers
which we use are banked. On the f71889ed however some more fan registers
have been banked including one which we use, by making the FAN_PROG_SEL bit
0, address 0x96 will point to the right register.
2) The second change is to see a FANx_TEMP_SEL value of 0 as pointing to
a PECI / AMDSI value, and thus disable our pwm related sysfs attr.
This is correct for the f71889ed and on the f71889fg 0 is a reserved
value, so we should never see it and if we do, disabling the pwm related
sysfs attr is a sane thing to do.
