2015-02-17watchdog: gpio_wdt: Add "always_running" feature to GPIO watchdogMike Looijmans
On some chips, like the TPS386000, the trigger cannot be disabled and the CPU must keep toggling the line at all times. Add a switch "always_running" to keep toggling the GPIO line regardless of the state of the soft part of the watchdog. The "armed" member keeps track of whether a timeout must also cause a reset.

2015-02-17watchdog: da9063: Add restart handler supportGeert Uytterhoeven
Register a restart handler for the da9063 watchdog. System restart is triggered by sending the shutdown command to the PMIC. As more-suitable restart handlers may exist, the priority of the watchdog restart handler is set to 128. The actual restart method was inspired by a platform-specific patch from the BSP by Hisashi Nakamura <hisashi.nakamura.ak@renesas.com>.

2015-02-17IB/iser: Fix memory regions possible leakSagi Grimberg
When teardown process starts during live IO, we need to keep the memory regions pool (frmr/fmr) until all in-flight tasks are properly released, since each task may return a memory region to the pool. In order to do this, we pass a destroy flag to iser_free_ib_conn_res to indicate we can destroy the device and the memory regions pool. iser_conn_release will pass it as true and also DEVICE_REMOVAL event (we need to let the device to properly remove). Also, Since we conditionally call iser_free_rx_descriptors, remove the extra check on iser_conn->rx_descs.

2015-02-17locks: remove conditional lock release in middle of flock_lock_fileJeff Layton
As Linus pointed out: Say we have an existing flock, and now do a new one that conflicts. I see what looks like three separate bugs. - We go through the first loop, find a lock of another type, and delete it in preparation for replacing it - we *drop* the lock context spinlock. - BUG #1? So now there is no lock at all, and somebody can come in and see that unlocked state. Is that really valid? - another thread comes in while the first thread dropped the lock context lock, and wants to add its own lock. It doesn't see the deleted or pending locks, so it just adds it - the first thread gets the context spinlock again, and adds the lock that replaced the original - BUG #2? So now there are *two* locks on the thing, and the next time you do an unlock (or when you close the file), it will only remove/replace the first one. ...remove the "drop the spinlock" code in the middle of this function as it has always been suspicious. This should eliminate the potential race that can leave two locks for the same struct file on the list. He also pointed out another thing as a bug -- namely that you flock_lock_file removes the lock from the list unconditionally when doing a lock upgrade, without knowing whether it'll be able to set the new lock. Bruce pointed out that this is expected behavior and may help prevent certain deadlock situations. We may want to revisit that at some point, but it's probably best that we do so in the context of a different patchset.

2015-02-17net: dsa: Set valid phy interface typeGuenter Roeck
If the phy interface mode is not found in devicetree, or if devicetree is not configured, of_get_phy_mode returns -ENODEV. The current code sets the phy interface mode to the return value from of_get_phy_mode without checking if it is valid. This invalid phy interface mode is passed as parameter to of_phy_connect or to phy_connect_direct. This sets the phy interface mode to the invalid value, which in turn causes problems for any code using phydev->interface.

The uses of "rcu_assign_pointer()" are NULLing out the pointers. According to RCU_INIT_POINTER()'s block comment: "1.

According to RCU_INIT_POINTER()'s block comment 3.a, it can be used if "1. This use of RCU_INIT_POINTER() is NULLing out the pointer" it is better to use it instead of rcu_assign_pointer() because it has a smaller overhead. "3. The referenced data structure has already been exposed to readers either at compile time or via rcu_assign_pointer() -and- a.

2015-02-17i2c: iproc: Add Broadcom iProc I2C DriverRay Jui
Add initial support to the Broadcom iProc I2C controller found in the iProc family of SoCs. The iProc I2C controller has separate internal TX and RX FIFOs, each has a size of 64 bytes. The iProc I2C controller supports two bus speeds including standard mode (100kHz) and fast mode (400kHz) Signed-off-by: Ray Jui <rjui@broadcom.com> Reviewed-by: Scott Branden <sbranden@broadcom.com> Reviewed-by: Kevin Cernekee <cernekee@chromium.org> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

When DRAM errors occur on memory controllers after EDAC_MAX_MCS (16), the kernel fatally dereferences unallocated structures, see splat below; this occurs on at least NumaConnect systems. Fix by checking if a memory controller info structure was found.

2015-02-17ALSA: usb-audio: Don't attempt to get Lifecam HD-5000 sample rateJoe Turner
Adds a quirk to disable the check that the sample rate has been set correctly, as the Lifecam does not support getting the sample rate. This means that we don't need to wait for the USB timeout when attempting to get the sample rate. Waiting for the timeout causes problems in some applications, which give up on the device acquisition process before it has had time to complete, resulting in no sound.

2015-02-16rtc: add driver for DS1685 family of real time clocksJoshua Kinard
This adds a driver for the Dallas/Maxim DS1685-family of RTC chips. It supports the DS1685/DS1687, DS1688/DS1691, DS1689/DS1693, DS17285/DS17287, DS17485/DS17487, and DS17885/DS17887 RTC chips. These chips are commonly found in SGI O2 and SGI Octane systems. It was originally derived from a driver patch submitted by Matthias Fuchs many years ago for use in EPPC-405-UC modules, which also used these RTCs. In addition to the time-keeping functions, this RTC also handles the shutdown mechanism of the O2 and Octane and acts as a partial NVRAM for the boot PROMS in these systems. Verified on both an SGI O2 and an SGI Octane.
