2016-12-09hwmon: (core) Rename groups parameter in API to extra_groupsGuenter Roeck
The 'groups' parameter of hwmon_device_register_with_info() and devm_hwmon_device_register_with_info() is only necessary if extra non-standard attributes need to be provided. Rename the parameter to extra_groups and clarify the documentation. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2016-12-09hwmon: (core) Explain why at least two attribute groups are allocatedGuenter Roeck
A list of sysfs attribute groups is NULL-terminated, so we always need to allocate data for at least two groups (the dynamically generated group plus the NULL pointer). Add a comment to explain the situation. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2016-12-09hwmon: (core) Make is_visible callback truly mandatoryGuenter Roeck
The is_visible callback provides the sysfs attribute mode and is thus truly mandatory as documented. Check it once at registration and remove other checks for its existence. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2016-12-09hwmon: (core) Deprecate hwmon_device_register()Guenter Roeck
Inform the user that hwmon_device_register() is deprecated, and suggest conversion to the newest API. Also remove hwmon_device_register() from the kernel API documentation. Note that hwmon_device_register() is not marked as __deprecated() since doing so might result in build errors. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2016-12-09hwmon: (core) Clarify use of chip attributesGuenter Roeck
Describing chip attributes as "attributes which apply to the entire chip" is confusing. Rephrase to "attributes which are not bound to a specific input or output". Also rename hwmon_chip_attr_templates[] to hwmon_chip_attrs[] to indicate that the respective strings strings are not templates but actual attribute names.

2016-12-09hwmon: (coretemp) Simplify package managementThomas Gleixner
Keeping track of the per package platform devices requires an extra object, which is held in a linked list. The maximum number of packages is known at init() time. So the extra object and linked list management can be replaced by an array of platform device pointers in which the per package devices pointers can be stored. Lookup becomes a simple array lookup instead of a list walk. The mutex protecting the list can be removed as well because the array is only accessed from cpu hotplug callbacks which are already serialized.

2016-12-09hwmon: (coretemp) Use proper error codes in cpu online callbackThomas Gleixner
The cpu online callback returns success unconditionally even when the device has no support, micro code mismatches or device allocation fails. Only if CPU_HOTPLUG is disabled, the init function checks whether the device list is empty and removes the driver. This does not make sense. If CPU HOTPLUG is enabled then there is no point to keep the driver around when it failed to initialize on the already online cpus. The chance that not yet online CPUs will provide a functional interface later is very close to zero. Add proper error return codes, so the setup of the cpu hotplug states fails when the device cannot be initialized and remove all the magic cruft.

2016-12-09hwmon: (coretemp) Simplify sibling managementThomas Gleixner
The coretemp driver provides a sysfs interface per physical core. If hyperthreading is enabled and one of the siblings goes offline the sysfs interface is removed and then immeditately created again for the sibling. The only difference of them is the target cpu for the rdmsr_on_cpu() in the sysfs show functions. It's way simpler to keep a cpumask of cpus which are active in a package and only remove the interface when the last sibling goes offline. Otherwise just move the target cpu for the sysfs show functions to the still online sibling. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2016-12-09hwmon: (coretemp) Fixup target cpu for package when cpu is offlinedThomas Gleixner
When a CPU is offlined nothing checks whether it is the target CPU for the package temperature sysfs interface. As a consequence all future readouts of the package temperature return crap: 90000 which is Tjmax of that package. Check whether the outgoing CPU is the target for the package and assign it to some other still online CPU in the package. Protect the change against the rdmsr_on_cpu() in show_crit_alarm().

When trying to get a regulator we may get deferred and we see this noise: smsc911x 1b800000.ethernet-ebi2 (unnamed net_device) (uninitialized): couldn't get regulators -517 Then the driver continues anyway. Which means that the regulator may not be properly retrieved and reference counted, and may be switched off in case noone else is using it.

2016-12-09ibmveth: set correct gso_size and gso_typeThomas Falcon
This patch is based on an earlier one submitted by Jon Maxwell with the following commit message: "We recently encountered a bug where a few customers using ibmveth on the same LPAR hit an issue where a TCP session hung when large receive was enabled. Closer analysis revealed that the session was stuck because the one side was advertising a zero window repeatedly. We narrowed this down to the fact the ibmveth driver did not set gso_size which is translated by TCP into the MSS later up the stack. The MSS is used to calculate the TCP window size and as that was abnormally large, it was calculating a zero window, even although the sockets receive buffer was completely empty." We rely on the Virtual I/O Server partition in a pseries environment to provide the MSS through the TCP header checksum field. The stipulation is that users should not disable checksum offloading if rx packet aggregation is enabled through VIOS. Some firmware offerings provide the MSS in the RX buffer. This is signalled by a bit in the RX queue descriptor.

2016-12-09net: qcom/emac: add support for the Qualcomm Technologies QDF2400Timur Tabi
The QDF2432 and the QDF2400 have slightly different internal PHYs, so there are some programming differences. Some of the registers in the QDF2400 have moved, and some registers require different values during initialization. Because of the differences, and because HIDs are a scare resource, the ACPI tables specify the hardware version in an _HRV property. Version 1 is the QDF2432, and version 2 is the QDF2400. Any future SOC that has the same internal PHY but different programming requirements will be assigned the next available version number.

2016-12-09net: qcom/emac: move phy init code to separate filesTimur Tabi
The internal PHY of the EMAC differs on each SOC, and the list will only continue to grow. By separating the code into individual files, we can add support for more SOCs more cleanly. Note: The internal PHY is also sometimes called the SGMII device. We also stop referring to the various PHY variations by version number, so no more "v2", "v3", etc. Instead, the devices are named after the SOC they are, which is in sync with the device tree property names. Future patches will probably rearrange more code among the files. Signed-off-by: Timur Tabi <timur@codeaurora.org> Signed-off-by: David S. Miller <davem@davemloft.net>

Reorganize the E400 detection now that we have everything in place: switch the CPUs to broadcast mode after the LAPIC has been initialized and remove the facilities that were used previously on the idle path. Unfortunately static_cpu_has_bug() cannpt be used in the E400 idle routine because alternatives have been applied when the actual detection happens, so the static switching does not take effect and the test will stay false.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm fixes from Dan Williams: "Several fixes to the DSM (ACPI device specific method) marshaling implementation. I consider these urgent enough to send for 4.9 consideration since they fix the kernel's handling of ARS (Address Range Scrub) commands. Especially for platforms without machine-check-recovery capabilities, successful execution of ARS commands enables the platform to potentially break out of an infinite reboot problem if a media error is present in the boot path. There is also a one line fix for a device-dax read-only mapping regression. Commits 9a901f5495e2 ("acpi, nfit: fix extended status translations for ACPI DSMs") and 325896ffdf90 ("device-dax: fix private mapping restriction, permit read-only") are true regression fixes for changes introduced this cycle. Commit efda1b5d87cb ("acpi, nfit, libnvdimm: fix / harden ars_status output length handling") fixes the kernel's handling of zero-length results, this never would have worked in the past, but we only just recently discovered a BIOS implementation that emits this arguably spec non-compliant result. The remaining two commits are additional fall out from thinking through the implications of a zero / truncated length result of the ARS Status command. In order to mitigate the risk that these changes introduce yet more regressions they are backstopped by a new unit test in commit a7de92dac9f0 ("tools/testing/nvdimm: unit test acpi_nfit_ctl()") that mocks up inputs to acpi_nfit_ctl()" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: device-dax: fix private mapping restriction, permit read-only tools/testing/nvdimm: unit test acpi_nfit_ctl() acpi, nfit: fix bus vs dimm confusion in xlat_status acpi, nfit: validate ars_status output buffer size acpi, nfit, libnvdimm: fix / harden ars_status output length handling acpi, nfit: fix extended status translations for ACPI DSMs

2016-12-09block: improve handling of the magic discard payloadChristoph Hellwig
Instead of allocating a single unused biovec for discard requests, send them down without any payload. Instead we allow the driver to add a "special" payload using a biovec embedded into struct request (unioned over other fields never used while in the driver), and overloading the number of segments for this case. This has a couple of advantages: - we don't have to allocate the bio_vec - the amount of special casing for discard requests in the block layer is significantly reduced - using this same scheme for other request types is trivial, which will be important for implementing the new WRITE_ZEROES op on devices where it actually requires a payload (e.g. SCSI) - we can get rid of playing games with the request length, as we'll never touch it and completions will work just fine - it will allow us to support ranged discard operations in the future by merging non-contiguous discard bios into a single request - last but not least it removes a lot of code This patch is the common base for my WIP series for ranges discards and to remove discard_zeroes_data in favor of always using REQ_OP_WRITE_ZEROES, so it would be good to get it in quickly.

These usage are most for superblock write, so spearate superblock related flags. This should make the code clearer and also fix real bugs.

2016-12-08md: takeover should clear unrelated bitsShaohua Li
When we change level from raid1 to raid5, the MD_FAILFAST_SUPPORTED bit will be accidentally set, but raid5 doesn't support it. The same is true for the MD_HAS_JOURNAL bit.

2016-12-08net: xgene: avoid bogus maybe-uninitialized warningArnd Bergmann
In some configurations, gcc cannot trace the state of variables across a spin_unlock() barrier, leading to a warning about correct code: xgene_enet_main.c: In function 'xgene_enet_start_xmit': ../../../phy/mdio-xgene.h:112:14: error: 'mss_index' may be used uninitialized in this function [-Werror=maybe-uninitialized] Here we can trivially move the assignment before that spin_unlock, which reliably avoids the warning.

2016-12-08net: xgene: move xgene_cle_ptree_ewdn data off stackArnd Bergmann
The array for initializing the cle is set up on the stack with almost entirely constant data and then passed to a function that converts it into HW specific bit patterns. With the latest addition, the size of this array has grown to the point that we get a warning about potential stack overflow in allmodconfig builds: xgene_enet_cle.c: In function ‘xgene_enet_cle_init’: xgene_enet_cle.c:836:1: error: the frame size of 1032 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Looking a bit deeper at the usage, I noticed that the only modification of the data is in dead code, as we don't even use the cle module for phy_mode other than PHY_INTERFACE_MODE_XGMII. This means we can simply mark the structure constant and access it directly rather than passing the pointer down through another structure, making the code more efficient at the same time as avoiding the warning.
