2016-01-10ASoC: Intel: Skylake: enable interrupt as wake source in active suspendJeeja KP
In active suspend, any HDA interrupt should wake the system. When device enters active suspend, we need to enable HDA controller interrupt as wake source. Similarly disable HDA controller interrupt as wake source when exiting active suspend.

2016-01-10ASoC: Support registering a DAI dynamicallyMengdong Lin
Define API snd_soc_register_dai() to add a DAI dynamically and create the DAI widgets. Topology can use this API to register DAIs when probing a component with topology info. These DAIs's playback & capture widgets will be freed when the sound card is unregistered and the DAIs will be freed when cleaning up the component. And a dobj is embedded into the struct snd_soc_dai_driver. Topology can use the dobj to find the DAI drivers created by it and free them when the topology component is removed.

2016-01-10i2c: designware: Do not require clock when SSCN and FFCN are providedSuravee Suthikulpanit
The current driver uses input clock source frequency to calculate values for [SS|FS]_[HC|LC] registers. However, when booting ACPI, we do not currently have a good way to provide the frequency information. Instead, we can leverage the SSCN and FFCN ACPI methods, which can be used to directly provide these values. So, the clock information should no longer be required during probing. However, since clk can be invalid, additional checks must be done where we are making use of it.

2016-01-09vxlan: fix test which detect duplicate vxlan ifaceNicolas Dichtel
When a vxlan interface is created, the driver checks that there is not another vxlan interface with the same properties. To do this, it checks the existing vxlan udp socket. Since commit 1c51a9159dde, the creation of the vxlan socket is done only when the interface is set up, thus it breaks that test. Example: $ ip l a vxlan10 type vxlan id 10 group 239.0.0.10 dev eth0 dstport 0 $ ip l a vxlan11 type vxlan id 10 group 239.0.0.10 dev eth0 dstport 0 $ ip -br l | grep vxlan vxlan10 DOWN f2:55:1c:6a:fb:00 <BROADCAST,MULTICAST> vxlan11 DOWN 7a:cb:b9:38:59:0d <BROADCAST,MULTICAST> Instead of checking sockets, let's loop over the vxlan iface list.

NVDIMM devices, which can behave more like DRAM rather than block devices, may develop bad cache lines, or 'poison'. A block device exposed by the pmem driver can then consume poison via a read (or write), and cause a machine check. On platforms without machine check recovery features, this would mean a crash. The block device maintaining a runtime list of all known sectors that have poison can directly avoid this, and also provide a path forward to enable proper handling/recovery for DAX faults on such a device.
