Initial roundup of 4.5 merge window patches
- Remove usage of ib_query_device and instead store attributes in ib_device struct - Move iopoll out of block and into lib, rename to irqpoll, and use in several places in the rdma stack as our new completion queue polling library mechanism. Update the other block drivers that already used iopoll to use the new mechanism too. - Replace the per-entry GID table locks with a single GID table lock - IPoIB multicast cleanup - Cleanups to the IB MR facility - Add support for 64bit extended IB counters - Fix for netlink oops while parsing RDMA nl messages - RoCEv2 support for the core IB code - mlx4 RoCEv2 support - mlx5 RoCEv2 support - Cross Channel support for mlx5 - Timestamp support for mlx5 - Atomic support for mlx5 - Raw QP support for mlx5 - MAINTAINERS update for mlx4/mlx5 - Misc ocrdma, qib, nes, usNIC, cxgb3, cxgb4, mlx4, mlx5 updates - Add support for remote invalidate to the iSER driver (pushed through the RDMA tree due to dependencies, acknowledged by nab) - Update to NFSoRDMA (pushed through the RDMA tree due to dependencies, acknowledged by Bruce) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWoSygAAoJELgmozMOVy/dDjsP/2vbTda2MvQfkfkGEZBQdJSg 095RN0gQgCJdg78lAl8yuaK8r4VN/7uefpDtFdudH1I/Pei7X0wxN9R1UzFNG4KR AD53lz92IVPs15328SbPR2kvNWISR9aBFQo3rlElq3Grqlp0EMn2Ou1vtu87rekF aMllxr8Nl0uZhP+eWusOsYpJUUtwirLgRnrAyfqo2UxZh/TMIroT0TCx1KXjVcAg dhDARiZAdu3OgSc6OsWqmH+DELEq6dFVA5F+DDBGAb8bFZqlJc7cuMHWInwNsNXT so4bnEQ835alTbsdYtqs5DUNS8heJTAJP4Uz0ehkTh/uNCcvnKeUTw1c2P/lXI1k 7s33gMM+0FXj0swMBw0kKwAF2d9Hhus9UAN7NwjBuOyHcjGRd5q7SAnfWkvKx000 s9jVW19slb2I38gB58nhjOh8s+vXUArgxnV1+kTia1+bJSR5swvVoWRicRXdF0vh TvLX/BjbSIU73g1TnnLNYoBTV3ybFKQ6bVdQW7fzSTDs54dsI1vvdHXi3bYZCpnL HVwQTZRfEzkvb0AdKbcvf8p/TlaAHem3ODqtO1eHvO4if1QJBSn+SptTEeJVYYdK n4B3l/dMoBH4JXJUmEHB9jwAvYOpv/YLAFIvdL7NFwbqGNsC3nfXFcmkVORB1W3B KEMcM2we4bz+uyKMjEAD =5oO7 -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull rdma updates from Doug Ledford: "Initial roundup of 4.5 merge window patches - Remove usage of ib_query_device and instead store attributes in ib_device struct - Move iopoll out of block and into lib, rename to irqpoll, and use in several places in the rdma stack as our new completion queue polling library mechanism.

More power management and ACPI updates for v4.5-rc1
- Modify the driver core and the USB subsystem to allow USB devices to stay suspended over system suspend/resume cycles if they have been runtime-suspended already beforehand and fix some bugs on top of these changes (Tomeu Vizoso, Rafael Wysocki). - Update ACPICA to upstream revision 20160108, including updates of the ACPICA's copyright notices, a code fixup resulting from a regression fix that was necessary in the upstream code only (the regression fixed by it has never been present in Linux) and a compiler warning fix (Bob Moore, Lv Zheng). - Fix a recent regression in the cpuidle menu governor that broke it on practically all architectures other than x86 and make a couple of optimizations on top of that fix (Rafael Wysocki). - Clean up the selection of cpuidle governors depending on whether or not the kernel is configured for tickless systems (Jean Delvare). - Revert a recent commit that introduced a regression in the ACPI backlight driver, address the problem it attempted to fix in a different way and revert one more cosmetic change depending on the problematic commit (Hans de Goede). - Add two more ACPI backlight quirks (Hans de Goede). - Fix a few minor problems in the core devfreq code, clean it up a bit and update the MAINTAINERS information related to it (Chanwoo Choi, MyungJoo Ham). - Improve an error message in the ACPI fan driver (Andy Lutomirski). - Fix a recent build regression in the cpupower tool (Shreyas Prabhu). / -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABCAAGBQJWoCQ4AAoJEILEb/54YlRxLscQALEFVKSRnNaco72OqqRZs9Bu 1RI6TgHTpZxR+Ef0+QWqE1QMnDwfImGhKDbSRm/t3S2sMYYZbAOL8cu4y6GmkBv4 bOon/f9WEoPlQCFoo/6U4u8H45rNT5W9zX5+Bva8x+4Wu3n2J1QdvirnS5JHeHe1 o6tGLaHuZXSwX8SLnCk8gJYK1VhATxbubJtpcVtvlnAhO11qUAwsscCrkUmB60i7 5hLyrZb06hoa/hZVcIefGFuSd9qPhzDMQE2M20EohQ7UVkNJQdY9QNHMqCk2P42T nMWCNSwGnwfiO1p9ByXqunOFBCmyL7P+KV/DHsz6TFCVjz+jeG53Kqey9SkSJ/2W iaAE80K9MfOMvg8j7rib6fTn5uXBwRfqdeUDF/Hr64QqJoRn3R2LX4HmZe4L8ufb zA1rece67o8FD+7p7GkNbT3rPV/kA62tn/moFk446X5N+b261Kz90t1DVci8kRVf k+1gcvEdqO0GPpEHoirfXrBvQFixqkXakKj4r2aAob/DldQeLX7CkOUuRRJ1ykec bxwI9R0v8MlVe5rDxg+rPB0I9EFxRDmxqxpU5j0MRWxKnMRzLvBtHuk8YNVS/eU1 xwyJOGcwF6yI0PaCFggPqmhebSrWLE7wJxaK+3bC+yiDTvHYPjB+4MfQrmkRAwwM azgb+ZgXDYx5wXeb8EjB =bKJ9 -----END PGP SIGNATURE----- Merge tag 'pm+acpi-4.5-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull more power management and ACPI updates from Rafael Wysocki: "This includes fixes on top of the previous batch of PM+ACPI updates and some new material as well. From the new material perspective the most significant are the driver core changes that should allow USB devices to stay suspended over system suspend/resume cycles if they have been runtime-suspended already beforehand. Apart from that, ACPICA is updated to upstream revision 20160108 (cosmetic mostly, but including one fixup on top of the previous ACPICA update) and there are some devfreq updates the didn't make it before (due to timing). A few recent regressions are fixed, most importantly in the cpuidle menu governor and in the ACPI backlight driver and some x86 platform drivers depending on it.

selftests/x86: Test __kernel_sigreturn and __kernel_rt_sigreturn
The vdso-based sigreturn mechanism is fragile and isn't used by modern glibc so, if we break it, we'll only notice when someone tests an unusual libc. Add an explicit selftest. [ I wrote this while debugging a Bionic breakage -- my first guess was that I had somehow messed up sigreturn. I've caused problems in that code before, and it's really easy to fail to notice it because there's nothing on a modern distro that needs vdso-based sigreturn. ] Signed-off-by: Andy Lutomirski <luto@kernel.org> Cc: Andy Lutomirski <luto@amacapital.net> Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Gerst <brgerst@gmail.com> Cc: Denys Vlasenko <dvlasenk@redhat.com> Cc: H.

Power management and ACPI updates for v4.5-rc1
- Add a debugfs-based interface for interacting with the ACPICA's AML debugger introduced in the previous cycle and a new user space tool for that, fix some bugs related to the AML debugger and clean up the code in question (Lv Zheng, Dan Carpenter, Colin Ian King, Markus Elfring). - Update ACPICA to upstream revision 20151218 including a number of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng, Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box, Rafael Wysocki). In particular, the previously added erroneous support for the _SUB object is dropped, the concatenate operator will support all ACPI objects now, the Debug Object handling is improved, the SuperName handling of parameters being control methods is fixed, the ObjectType operator handling is updated to follow ACPI 5.0A and the handling of CondRefOf and RefOf is updated accordingly, module-level code will be executed after loading each ACPI table now (instead of being run once after all tables containing AML have been loaded), the Operation Region handlers management is updated to fix some reported problems and a the ACPICA code in the kernel is more in line with the upstream now. - Update the ACPI backlight driver to provide information on whether or not it will generate key-presses for brightness change hotkeys and update some platform drivers (dell-wmi, thinkpad_acpi) to use that information to avoid sending double key-events to users pace for these, add new ACPI backlight quirks (Hans de Goede, Aaron Lu, Adrien Schildknecht). - Improve the ACPI handling of interrupt GPIOs (Christophe Ricard). - Fix the handling of the list of device IDs of device objects found in the ACPI namespace and add a helper for checking if there is a device object for a given device ID (Lukas Wunner). - Change the logic in the ACPI namespace scanning code to create struct acpi_device objects for all ACPI device objects found in the namespace even if _STA fails for them which helps to avoid device enumeration problems on Microsoft Surface 3 (Aaron Lu). - Add support for the APM X-Gene ACPI I2C device to the ACPI driver for AMD SoCs (Loc Ho). - Fix the long-standing issue with the DMA controller on Intel SoCs where ACPI tables have no power management support for the DMA controller itself, but it can be powered off automatically when the last (other) device on the SoC is powered off via ACPI and clean up the ACPI driver for Intel SoCs (acpi-lpss) after previous attempts to fix that problem (Andy Shevchenko). - Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King, Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki, Sinan Kaya). - Update the device properties framework for better handling of built-in properties, add support for built-in properties to the platform bus type, update the MFD subsystem's handling of device properties and add support for passing default configuration data as device properties to the intel-lpss MFD drivers, convert the designware I2C driver to use the unified device properties API and add a fallback mechanism for using default built-in properties if the platform firmware fails to provide the properties as expected by drivers (Andy Shevchenko, Mika Westerberg, Heikki Krogerus, Andrew Morton). - Add new Device Tree bindings to the Operating Performance Points (OPP) framework and update the exynos4412 DT binding accordingly, introduce debugfs support for the OPP framework (Viresh Kumar, Bartlomiej Zolnierkiewicz). - Migrate the mt8173 cpufreq driver to the new OPP bindings (Pi-Cheng Chen). - Update the cpufreq core to make the handling of governors more efficient, especially on systems where policy objects are shared between multiple CPUs (Viresh Kumar, Rafael Wysocki). - Fix cpufreq governor handling on configurations with CONFIG_HZ_PERIODIC set (Chen Yu). - Clean up the cpufreq core code related to the boost sysfs knob support and update the ACPI cpufreq driver accordingly (Rafael Wysocki). - Add a new cpufreq driver for ST platforms and corresponding Device Tree bindings (Lee Jones). - Update the intel_pstate driver to allow the P-state selection algorithm used by it to depend on the CPU ID of the processor it is running on, make it use a special P-state selection algorithm (with an IO wait time compensation tweak) on Atom CPUs based on the Airmont and Silvermont cores so as to reduce their energy consumption and improve intel_pstate documentation (Philippe Longepe, Srinivas Pandruvada). - Update the cpufreq-dt driver to support registering cooling devices that use the (P * V^2 * f) dynamic power draw formula where V is the voltage, f is the frequency and P is a constant coefficient provided by Device Tree and update the arm_big_little cpufreq driver to use that support (Punit Agrawal). - Assorted cpufreq driver (cpufreq-dt, qoriq, pcc-cpufreq, blackfin-cpufreq) updates (Andrzej Hajda, Hongtao Jia, Jacob Tanenbaum, Markus Elfring). - cpuidle core tweaks related to polling and measured_us calculation (Rik van Riel). - Removal of modularity from a few cpuidle drivers (clps711x, ux500, exynos) that cannot be built as modules in practice (Paul Gortmaker). - PM core update to prevent devices from being probed during system suspend/resume which is generally problematic and may lead to inconsistent behavior (Grygorii Strashko). - Assorted updates of the PM core and related code (Julia Lawall, Manuel Pégourié-Gonnard, Maruthi Bayyavarapu, Rafael Wysocki, Ulf Hansson). - PNP bus type updates (Christophe Le Roy, Heiner Kallweit). -

The most significant new feature is the debugfs-based interface to the ACPICA's AML debugger added in the previous cycle and a new user space tool for accessing it. On the cpufreq front, the core is updated to handle governors more efficiently, particularly on systems where a single cpufreq policy object is shared between multiple CPUs, and there are quite a few changes in drivers (intel_pstate, cpufreq-dt etc). The device properties framework is updated to handle built-in (ie included in the kernel itself) device properties better, among other things by adding a fallback mechanism that will allow drivers to provide default properties to be used in case the plaform firmware doesn't provide the properties expected by them. The Operating Performance Points (OPP) framework gets new DT bindings and debugfs support. A new cpufreq driver for ST platforms is added and the ACPI driver for AMD SoCs will now support the APM X-Gene ACPI I2C device. The rest is mostly fixes and cleanups all over.

selftests/x86: Disable the ldt_gdt_64 test for now
ldt_gdt.c relies on cross-cpu invalidation of SS to do one of its tests. On 32-bit builds, this works fine, but on 64-bit builds, it only works if the kernel has proper SS sigcontext handling for 64-bit user programs. Since the SS fixes are currently reverted, restrict the test case to 32 bits for now. In principle, I could change the test to use a different segment register, but it would be messy: CS can't point to the LDT for 64-bit code, and the other registers don't result in immediate faults because they aren't reloaded on kernel -> user transitions. When we fix sigcontext (in 4.6?), we can revert this.
