Prepare for new format checking function by renaming functions and moving reusable code to separate functions: - Move sanity checks into a new function and make it reusable. - Move common format code to a new function called dasd_eckd_format_process_data. - Create the generic function dasd_eckd_format_build_ccw_req, which itself will then decide what ccw request is being built according to the input data.

2016-03-07s390/dasd: Simplify code in format logicJan Höppner
Currently, dasd_format is calling the format logic of a DASD discipline with PAV enabled. If that fails with an error code of -EAGAIN the value of retries is decremented and the discipline function is called with PAV turned off. The loop is supposed to try this up to 255 times until success. However, -EAGAIN can only occur once here and therefore the loop will never reach the 255 retries. So, replace the unnecessarily complicated loop logic and simply try again without PAV enabled in case of an -EAGAIN error.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v4.5 This is far too big a set of fixes for this late in the release cycle but the overwhelming bulk is essentially the same simple fix from Takashi for a cut'n'pasted 64 bit cleanliness issue in the userspace interface where drivers were accessing things using the wrong element in a union which worked OK on 32 bit platforms as the correct element happened to be aligned the same way but with 64 bit platforms ABIs are different and the two members of the union are laid out in different places. They aren't all tagged to stable since some of these chips have vanishingly little chance of being used in 64 bit systems. The other changes are: - A fix for Qualcomm devices to work on big endian systems. The original change is actually correct but triggered a bug in regmap which is too invasive to fix for this cycle and can be worked around by just letting regmap pick the default. - A fix for the Samsung I2S driver locking which wasn't using IRQ safe spinlocks when it needed to. - A fix for the new Intel Sky Lake driver forgetting that C pointer arithmetic takes the type of the pointer into consideration. - A revert of a change to the FSL SSI driver that broke some systems. - A fix for the cleanup path of the wm9713 driver. - A fix for some incorrect register definitions in the ADAU17x1 driver that caused misclocking in some configurations. - A fix for the tracepoints for jack detection to avoid using an internal field of the core jack structure which is no longer present in all configurations. - A fix for another of the new Intel drivers which tried to write to a string literal.
2016-03-07ARM: dts: dra7: do not gate cpsw clock due to errata i877Mugunthan V N
Errata id: i877 Description: ------------ The RGMII 1000 Mbps Transmit timing is based on the output clock (rgmiin_txc) being driven relative to the rising edge of an internal clock and the output control/data (rgmiin_txctl/txd) being driven relative to the falling edge of an internal clock source. If the internal clock source is allowed to be static low (i.e., disabled) for an extended period of time then when the clock is actually enabled the timing delta between the rising edge and falling edge can change over the lifetime of the device. This can result in the device switching characteristics degrading over time, and eventually failing to meet the Data Manual Delay Time/Skew specs. To maintain RGMII 1000 Mbps IO Timings, SW should minimize the duration that the Ethernet internal clock source is disabled. Note that the device reset state for the Ethernet clock is "disabled". Other RGMII modes (10 Mbps, 100Mbps) are not affected Workaround: ----------- If the SoC Ethernet interface(s) are used in RGMII mode at 1000 Mbps, SW should minimize the time the Ethernet internal clock source is disabled to a maximum of 200 hours in a device life cycle. This is done by enabling the clock as early as possible in IPL (QNX) or SPL/u-boot (Linux/Android) by setting the register CM_GMAC_CLKSTCTRL[1:0]CLKTRCTRL = 0x2:SW_WKUP. So, do not allow to gate the cpsw clocks using ti,no-idle property in cpsw node assuming 1000 Mbps is being used all the time. If someone does not need 1000 Mbps and wants to gate clocks to cpsw, this property needs to be deleted in their respective board files.

commit 4d5cfcba2f6e ('tipc: fix connection abort during subscription cancel'), removes the check for a valid subscription before calling tipc_nametbl_subscribe(). This will lead to a nullptr exception when we process a subscription cancel request. For a cancel request, a null subscription is passed to tipc_nametbl_subscribe() resulting in exception.

The routing uses the GPIO namespace and not the pin namespace so a lookup is preformed on the pin. Routing configuration is done in the device tree by using the new nxp,gpio-pin-interrupt property.

2016-03-07xfs: only run torn log write detection on dirty logsBrian Foster
XFS uses CRC verification over a sub-range of the head of the log to detect and handle torn writes. This torn log write detection currently runs unconditionally at mount time, regardless of whether the log is dirty or clean. This is problematic in cases where a filesystem might end up being moved across different, incompatible (i.e., opposite byte-endianness) architectures. The problem lies in the fact that log data is not necessarily written in an architecture independent format. For example, certain bits of data are written in native endian format. Further, the size of certain log data structures differs (i.e., struct xlog_rec_header) depending on the word size of the cpu. This leads to false positive crc verification errors and ultimately failed mounts when a cleanly unmounted filesystem is mounted on a system with an incompatible architecture from data that was written near the head of the log. Update the log head/tail discovery code to run torn write detection only when the log is not clean. This means something other than an unmount record resides at the head of the log and log recovery is imminent. It is a requirement to run log recovery on the same type of host that had written the content of the dirty log and therefore CRC failures are legitimate corruptions in that scenario.

2016-03-07xfs: refactor in-core log state update to helperBrian Foster
Once the record at the head of the log is identified and verified, the in-core log state is updated based on the record. This includes information such as the current head block and cycle, the start block of the last record written to the log, the tail lsn, etc. Once torn write detection is conditional, this logic will need to be reused. Factor the code to update the in-core log data structures into a new helper function. This patch does not change behavior.

2016-03-07xfs: refactor unmount record detection into helperBrian Foster
Once the mount sequence has identified the head and tail blocks of the physical log, the record at the head of the log is located and examined for an unmount record to determine if the log is clean. This currently occurs after torn write verification of the head region of the log. This must ultimately be separated from torn write verification and may need to be called again if the log head is walked back due to a torn write (to determine whether the new head record is an unmount record). Separate this logic into a new helper function. This patch does not change behavior.

2016-03-07xfs: separate log head record discovery from verificationBrian Foster
The code that locates the log record at the head of the log is buried in the log head verification function. This is fine when torn write verification occurs unconditionally, but this behavior is problematic for filesystems that might be moved across systems with different architectures. In preparation for separating examination of the log head for unmount records from torn write detection, lift the record location logic out of the log verification function and into the caller.

2016-03-05scsi: mvumi: use __maybe_unused to hide pm functionsArnd Bergmann
The mvumi scsi hides the references to its suspend/resume functions in an #ifdef but does not hide the implementation the same way: drivers/scsi/mvumi.c:2632:12: error: 'mvumi_suspend' defined but not used [-Werror=unused-function] drivers/scsi/mvumi.c:2651:12: error: 'mvumi_resume' defined but not used [-Werror=unused-function] This adds __maybe_unused annotations so the compiler knows it can silently drop them instead of warning, while avoiding the addition of another #ifdef.
