git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management and ACPI fixes from Rafael Wysocki: "These are fixes mostly, for a few changes made in this cycle (the intel_idle driver, the OPP library, the ACPI EC driver, turbostat) and for some issues that have just been discovered (ACPI PCI IRQ management, PCI power management documentation, turbostat), with a couple of cleanups on top of them. Specifics: - intel_idle driver fixup for the recently added Skylake chips support (Len Brown). - Operating Performance Points (OPP) library fix related to the recently added support for new DT bindings and a fix for a typo in a comment (Viresh Kumar, Stephen Boyd). - ACPI EC driver fix for a recently introduced memory leak in an error code path (Lv Zheng). - ACPI PCI IRQ management fix for the issue where an ISA IRQ is shared with a PCI device which requires it to be configured in a different way and may cause an interrupt storm to happen as a result with an extra ACPI SCI IRQ handling simplification on top of it (Jiang Liu). - Update of the PCI power management documentation that became outdated and started to actively confuse the readers to make it actually reflect the code (Rafael J Wysocki). - turbostat fixes including an IVB Xeon regression fix (related to the --debug command line option), Skylake adjustment for the TSC running at a frequency that doesn't match the base one exactly, and a Knights Landing quirk to account for the fact that it only updates APERF and MPERF every 1024 clock cycles plus bumping up the turbostat version number (Len Brown, Hubert Chrzaniuk)" * tag 'pm+acpi-4.3-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: tools/power turbosat: update version number tools/power turbostat: SKL: Adjust for TSC difference from base frequency tools/power turbostat: KNL workaround for %Busy and Avg_MHz tools/power turbostat: IVB Xeon: fix --debug regression ACPI / PCI: Remove duplicated penalty on SCI IRQ ACPI, PCI, irq: Do not share PCI IRQ with ISA IRQ ACPI / EC: Fix a memory leak issue in acpi_ec_query() PM / OPP: Fix typo modifcation -> modification PCI / PM: Update runtime PM documentation for PCI devices PM / OPP: of_property_count_u32_elems() can return errors intel_idle: Skylake Client Support - updated

2015-09-30net/mlx4: Handle return codes in mlx4_qp_attach_commonRobb Manes1-3/+4
Both new_steering_entry() and existing_steering_entry() return values based on their success or failure, but currently they fall through silently. This can make troubleshooting difficult, as we were unable to tell which one of these two functions returned errors or specifically what code was returned. This patch remedies that situation by passing the return codes to err, which is returned by mlx4_qp_attach_common() itself. This also addresses a leak in the call to mlx4_bitmap_free() as well.

2015-09-29net/ibm/emac: bump version numbers for correct work with ethtoolIvan Mikhaylov1-3/+3
The size of the MAC register dump used to be the size specified by the reg property in the device tree. Userland has no good way of finding out that size, and it was not specified consistently for each MAC type, so ethtool would end up printing junk at the end of the register dump if the device tree didn't match the size it assumed. Using the new version numbers indicates unambiguously that the size of the MAC register dump is dependent only on the MAC type.

Currently poweroff/halt results in a reboot on the Raspberry Pi. The firmware uses the RSTS register to know which partiton to boot from. The partiton value is spread into bits 0, 2, 4, 6, 8, 10.

gic_handle_shared_int reads the GIC interrupt pending & mask registers directly into a bitmap, which is defined as an array of unsigned longs. The GIC pending registers may be 32 bits wide if the CM is older than CM3, regardless of the bit width of the CPU, but for MIPS64 kernels the unsigned longs in the bitmap will be 64 bits wide. In this case we need to perform 2 x 32 bit reads per 64 bit unsigned long in order to avoid missing interrupts.

2015-09-26IB/ipoib: increase the max mcast backlog queueDoug Ledford1-1/+1
When performing sendonly joins, we queue the packets that trigger the join until the join completes. This may take on the order of hundreds of milliseconds. It is easy to have many more than three packets come in during that time. Expand the maximum queue depth in order to try and prevent dropped packets during the time it takes to join the multicast group. Signed-off-by: Doug Ledford <dledford@redhat.com>

2015-09-26ACPI, PCI, irq: Do not share PCI IRQ with ISA IRQJiang Liu2-0/+14
Avoid IRQs occupied by ISA IRQs when allocating IRQs for PCI link devices, otherwise it may cause interrupt storm due to incompatible pin attributes. This issue was triggered on a KVM virtual machine, which 1) uses IRQ9 for SCI in high level mode. 2) defines an PCI interrupt link device (LNKS) with IRQ9 as the only possible irq. 3) has an PCI device referring to link device LNKS. So it causes interrupt storm when enabling the PCI device because PCI IRQ works in low level mode.

2015-09-26ACPI / EC: Fix a memory leak issue in acpi_ec_query()Lv Zheng1-0/+2
When query handler is not found, "result" is actually stil 0, and "struct acpi_ec_query" is not NULL, so the deletion code of "struct acpi_ec_query" at the end of the function cannot be invoked. As a consequence, memory leak can be observed. The issue is introduced by this commit: Commit: 02b771b64b73226052d6e731a0987db3b47281e9 Subject: ACPI / EC: Fix an issue caused by the serialized _Qxx This patch fixes such memory leakage.

2015-09-25IB/ipoib: Make sendonly multicast joins create the mcast groupDoug Ledford1-10/+12
Since IPoIB should, as much as possible, emulate how multicast sends work on Ethernet for regular TCP/IP apps, there should be no requirement to subscribe to a multicast group before your sends are properly sent. However, due to the difference in how multicast is handled on InfiniBand, we must join the appropriate multicast group before we can send to it. Previously we tried not to trigger the auto-create feature of the subnet manager when doing this because we didn't have tracking of these sendonly groups and the auto-creation might never get undone. The previous patch added timing to these sendonly joins and allows us to leave them after a reasonable idle expiration time. So supply all of the information needed to auto-create group.
