2016-01-10m68k: Provide __phys_to_pfn() and __pfn_to_phys()Sudip Mukherjee
The defconfig build of m68k was failing with the error: implicit declaration of function '__pfn_to_phys' Other architectures have added <asm/memory.h>, but if we do so here then we will also get redeclaration of some other functions. So it is better to copy these macros into page.h.

2016-01-10ASoC: Make aux_dev more like a generic componentMengdong Lin
aux_dev is mainly used by the machine driver to specify analog devices, which are registered as codecs. Making it more like a generic component can help the machine driver to use it to specify any component with topology info by name. Details: - Remove the stub 'rtd_aux' array from the soc card. - Add a list 'aux_comp_list' to store the components of aux_devs. And add a list head 'list_aux' to struct snd_soc_component, for adding such components to the above list. - Add a 'init' ops to a component for machine specific init. soc_bind_aux_dev() will set it to be aux_dev's init. And it will be called when probing the component. - soc_bind_aux_dev() will also search components by name of an aux_dev, since it may not be a codec. - Move probing of aux_devs before checking new DAI links brought by topology. - Move removal of aux_devs later than removal of links. Because topology of aux components may register DAIs and the DAI drivers will go with removal of the aux components, we want soc_remove_link_dais() to remove the DAIs at first.

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.

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.
