The change adds watchdog pretimeout notification handling to imx2_wdt
driver, if device data contains information about a valid interrupt.
It is unlikely but still possible (e.g. through a software limitation)
that only a subset of watchdogs on SoC has interrupt lines, hence
functionally the devices from these two groups have different
capabilities, and this is reflected in different watchdog_info
structs assigned to the devices.

The change converts watchdog device attribute "pretimeout_governor" from
read-only to read-write type to allow users to select a desirable
watchdog pretimeout governor in runtime, e.g.
% echo -n panic > /sys/..../watchdog/watchdog0/pretimeout
To get this working a list of registered pretimeout governors is created
and a new helper function watchdog_pretimeout_governor_set() is exported
to watchdog_dev.c.
If a selected governor is gone, a watchdog device pretimeout notification
is delegated to a default built-in pretimeout governor.

The change adds panic watchdog pretimeout governor, on watchdog
pretimeout event the kernel shall panic. In general watchdog
pretimeout event means that something essentially bad is going on the
system, for example a process scheduler stalls or watchdog feeder is
killed due to OOM, so printing out information attendant to panic and
before likely unavoidable reboot caused by a watchdog may help to
determine a root cause of the issue.

The change adds noop watchdog pretimeout governor, only an
informational message is printed to the kernel log buffer when a
watchdog triggers a pretimeout event.
While introducing the first pretimeout governor the selected design
assumes that the default pretimeout governor is selected by its name
and it is always built-in, thus the default pretimeout governor can
not be unregistered and the correspondent check can be removed from
the watchdog_unregister_governor() function.

The change adds a simple watchdog pretimeout framework infrastructure,
its purpose is to allow users to select a desired handling of watchdog
pretimeout events, which may be generated by some watchdog devices.
A user selects a default watchdog pretimeout governor during
compilation stage.
Watchdogs with WDIOF_PRETIMEOUT capability now have one more device
attribute in sysfs, pretimeout_governor attribute is intended to display
the selected watchdog pretimeout governor.
The framework has no impact at runtime on watchdog devices with no
WDIOF_PRETIMEOUT capability set.

Pull ARM fixes from Russell King:
"Most of this update are fixes primarily discovered from testing on the
older StrongARM 1110 and PXA systems, as a result of recent interest
from several people in these platforms:
- Locomo interrupt handling incorrectly stores the handler data in
the chip's private data slot: when Locomo is combined with an
interrupt controller who's chip uses the chip private data, this
leads to an oops.
- SA1111 was missing a call to clk_disable() to clean up after a
failed probe.
- SA1111 and PCMCIA suspend/resume was broken:
The PCMCIA "ds" layer was using the legacy bus suspend/resume
methods, which the core PM code is no longer calling as a result of
device_pm_check_callbacks() introduced in commit aa8e54b559
("PM / sleep: Go direct_complete if driver has no callbacks").
SA1111 was broken due to changes to PCMCIA which makes PCMCIA
suspend itself later than the SA1111 code expects, and resume
before the SA1111 code has initialised access to the pcmcia
sub-device.
- the default SA1111 interrupt mask polarity got messed up when it
was converted to use a dynamic interrupt base number for its
interrupts.
- fix platform_get_irq() error code propagation, which was causing
problems on platforms where the interrupt may not be available at
probe time in DT setups.
- fix the lack of clock to PCMCIA code on PXA platforms, which was
omitted in conversions of PXA to CCF.
- fix an oops in the PXA PCMCIA code caused by a previous commit not
realising that Lubbock is different from the rest of the PXA PCMCIA
drivers.
- ensure that SA1111 low-level PCMCIA drivers propagate their error
codes to the main probe function, rather than the driver silently
accepting a failure.
- fix the sa11xx debugfs reporting of timing information, which
always indicated zero due to the clock being a factor of 1000 out.
- fix the polarity of the status change signal reported from the
sockets.
Lastly, one ARM specific commit from Stefan Agner fixing the LPAE
cache attributes"

The userspace memory region 'mr' is allocated with kzalloc in
__rvt_alloc_mr however it is incorrectly being freed with vfree in
__rvt_free_mr. Fix this by using kfree to free it.

rxe_requester() is sending a pkt with rxe_xmit_packet() and
then calls rxe_update() to update the wqe and qp's psn values.
But sometimes the response is received before the requester
had time to update the wqe in which case the completer
acts on errornous wqe values.
This fix updates the wqe and qp before actually sending
the request and rolls back when xmit fails.

When handling ack for atomic opcodes like "fetch&add"
or "cmp&swp", the method send_atomic_ack() saves the ack
before sending it, in case it gets lost and never reach the
requester. In which case the method duplicate_request()
will need to find it using the duplicated request.psn.
But send_atomic_ack() used a wrong psn value and thus
the above ack was never found.
This fix uses the ack.psn to locate the ack in case
its needed.
This fix also copies the ack packet to the skb's control buffer
since duplicate_request() will need it when calling rxe_xmit_packet()
