2015-10-02irqchip/gic-v3-its: Count additional LPIs for the aliased devicesMarc Zyngier1-1/+1
When configuring the interrupt mapping for a new device, we iterate over all the possible aliases to account for their maximum MSI allocation. This was introduced by e8137f4f5088 ("irqchip: gicv3-its: Iterate over PCI aliases to generate ITS configuration"). Turns out that the code doing that is a bit braindead, and repeatedly accounts for the same device over and over. Fix this by counting the actual alias that is passed to us by the core code.

2015-10-02md: clear CHANGE_PENDING in readonly arrayShaohua Li1-0/+1
If faulty disks of an array are more than allowed degraded number, the array enters error handling. It will be marked as read-only with MD_CHANGE_PENDING/RECOVERY_NEEDED set. But currently recovery doesn't clear CHANGE_PENDING bit for read-only array. If MD_CHANGE_PENDING is set for a raid5 array, all returned IO will be hold on a list till the bit is clear. But recovery nevery clears this bit, the IO is always in pending state and nevery finish. This has bad effects like upper layer can't get an IO error and the array can't be stopped.

2015-10-02drm/dp/mst: split connector registration into two parts (v2)Dave Airlie3-6/+22
In order to cache the EDID properly for tiled displays, we need to retrieve it before we register the connector with userspace, otherwise userspace can call get resources and try and get the edid before we've even cached it. This fixes some problems when hotplugging mst monitors, with X/mutter running. As mutter seems to get 0 modes for one of the monitors in the tile. v2: fix warning in radeon handle tile setting in cached path rather than get edid path.

2015-10-02drm/dp/mst: fixup handling hotplug on port removal.Dave Airlie1-10/+26
output ports should always have a connector, unless in the rare case connector allocation fails in the driver. In this case we only need to teardown the pdt, and free the struct, and there is no need to send a hotplug msg. In the case were we add the port to the destroy list we need to send a hotplug if we destroy any connectors, so userspace knows to reprobe stuff. this patch also handles port->connector allocation failing which should be a rare event, but makes the code consistent.

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
