2017-06-14time/posix-timers: Move the compat copyouts to the nanosleep implementationsAl Viro
Turn restart_block.nanosleep.{rmtp,compat_rmtp} into a tagged union (kind = 1 -> native, kind = 2 -> compat, kind = 0 -> nothing) and make the places doing actual copyout handle compat as well as native (that will become a helper in the next commit). Result: compat wrappers, messing with reassignments, etc. are gone.

2017-06-13spi: Generalize SPI "master" to "controller"Geert Uytterhoeven
Now struct spi_master is used for both SPI master and slave controllers, it makes sense to rename it to struct spi_controller, and replace "master" by "controller" where appropriate. For now this conversion is done for SPI core infrastructure only. Wrappers are provided for backwards compatibility, until all SPI drivers have been converted. Noteworthy details: - SPI_MASTER_GPIO_SS is retained, as it only makes sense for SPI master controllers, - spi_busnum_to_master() is retained, as it looks up masters only, - A new field spi_device.controller is added, but spi_device.master is retained for compatibility (both are always initialized by spi_alloc_device()), - spi_flash_read() is used by SPI masters only.

2017-06-13usb: gadget: core: introduce ->udc_set_speed() methodFelipe Balbi
Sometimes, the gadget driver we want to run has max_speed lower than what the UDC supports. In such situations, UDC might want to make sure we don't try to connect on speeds not supported by the gadget driver (e.g. super-speed capable dwc3 with high-speed capable g_midi) because that will just fail. In order to make sure this situation never happens, we introduce a new optional ->udc_set_speed() method which can be implemented by interested UDC drivers.

2017-06-13driver core: add helper to reuse a device-tree nodeJohan Hovold
Add a helper function to be used when reusing the device-tree node of another device. It is fairly common for drivers to reuse the device-tree node of a parent (or other ancestor) device when creating class or bus devices (e.g. gpio chips, i2c adapters, iio chips, spi masters, serdev, phys, usb root hubs). But reusing a device-tree node may cause problems if the new device is later probed as for example driver core would currently attempt to reinitialise an already active associated pinmux configuration. Other potential issues include the platform-bus code unconditionally dropping the device-tree node reference in its device destructor, reinitialisation of other bus-managed resources such as clocks, and the recently added DMA-setup in driver core. Note that for most examples above this is currently not an issue as the devices are never probed, but this is a problem for the USB bus which has recently gained device-tree support. This was discovered and worked-around in a rather ad-hoc fashion by commit dc5878abf49c ("usb: core: move root hub's device node assignment after it is added to bus") by not setting the of_node pointer until after the root-hub device has been registered. Instead we can allow devices to reuse a device-tree node by setting a flag in their struct device that can be used by core, bus and driver code to avoid resources from being over-allocated. Note that the helper also grabs an extra reference to the device node, which specifically balances the unconditional put in the platform-device destructor.

2017-06-12udp: avoid a cache miss on dequeuePaolo Abeni
Since UDP no more uses sk->destructor, we can clear completely the skb head state before enqueuing. Amend and use skb_release_head_state() for that. All head states share a single cacheline, which is not normally used/accesses on dequeue. We can avoid entirely accessing such cacheline implementing and using in the UDP code a specialized skb free helper which ignores the skb head state.

2017-06-12soc: renesas: Rework Kconfig and Makefile logicGeert Uytterhoeven
The goals are to: - Allow precise control over and automatic selection of which (sub)drivers are used for which SoC, - Allow adding support for new SoCs easily, - Allow compile-testing of all (sub)drivers, - Keep driver selection logic in the subsystem-specific Kconfig, independent from the architecture-specific Kconfig (i.e. no "select" from arch/arm64/Kconfig.platforms), to avoid dependencies. This is implemented by: - Introducing Kconfig symbols for all drivers and sub-drivers, - Introducing the Kconfig symbol SOC_RENESAS, which is enabled automatically when building for a Renesas ARM platform, and which enables all required drivers without interaction of the user, based on SoC-specific ARCH_* symbols, - Allowing the user to enable any Kconfig symbol manually if COMPILE_TEST is enabled, - Using the new Kconfig symbols instead of the ARCH_* symbols to control compilation in the Makefile, - Always entering drivers/soc/renesas/ during the build.
