2017-03-02sched/headers: Prepare for new header dependencies before moving code to <linux/sched/loadavg.h>Ingo Molnar1-0/+1
We are going to split <linux/sched/loadavg.h> out of <linux/sched.h>, which will have to be picked up from a couple of .c files. Create a trivial placeholder <linux/sched/topology.h> file that just maps to <linux/sched.h> to make this patch obviously correct and bisectable.

2017-02-26platform/x86: asus-wmi: Detect quirk_no_rfkill from the DSDTJoão Paulo Rechi Vita1-4/+19
Some Asus laptops that have an airplane-mode indicator LED, also have the WMI WLAN user bit set, and the following bits in their DSDT: Scope (_SB) { (...) Device (ATKD) { (...) Method (WMNB, 3, Serialized) { (...) If (LEqual (IIA0, 0x00010002)) { OWGD (IIA1) Return (One) } } } } So when asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store the wlan state, it drives the airplane-mode indicator LED (through the call to OWGD) in an inverted fashion: the LED is ON when airplane mode is OFF (since wlan is ON), and vice-versa. This commit skips registering RFKill switches at all for these laptops, to allow the asus-wireless driver to drive the airplane mode LED correctly through the ASHS ACPI device. Relying on the presence of ASHS and ASUS_WMI_DSTS_USER_BIT avoids adding DMI-based quirks for at least 21 different laptops.

2017-02-24platform/x86: intel_turbo_max_3: make it explicitly non-modularPaul Gortmaker1-6/+5
The Kconfig currently controlling compilation of this code is: drivers/platform/x86/Kconfig:config INTEL_TURBO_MAX_3 drivers/platform/x86/Kconfig: bool "Intel Turbo Boost Max Technology 3.0 enumeration driver" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments. We do uncover some implicit includes during build coverage that were hidden behind the module.h which pulls in a lot of dependants.

Some Asus machines use 0x4/0x5 as their LED on/off values, while others use 0x0/0x1, as shown in the DSDT excerpts below. Luckily it seems this behavior is tied to different HIDs, after looking at 44 DSDTs from different Asus models. Another small difference is that a few of them call GWBL instead of OWGS, and SWBL instead of OWGD. That does not seem to make a difference for asus-wireless, and is additional reasoning to not try to call these methods directly.

2017-02-15goldfish: Sanitize the broken interrupt handlerThomas Gleixner1-5/+8
This interrupt handler is broken in several ways: - It loops forever when the op code is not decodeable - It never returns IRQ_HANDLED because the only way to exit the loop returns IRQ_NONE unconditionally. The whole concept of this is broken. Creating devices in an interrupt handler is beyond any point of sanity. Make it at least behave halfways sane so accidental users do not have to deal with a hard to debug lockup.
