2016-01-07phy: Move phy specific bus match into phy_deviceAndrew Lunn
Matching a driver to a device has both generic parts, and parts which are specific to PHY devices. Move the PHY specific parts into phy_device. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-01-07ftrace/module: Call clean up function when module init fails earlySteven Rostedt (Red Hat)
If the module init code fails after calling ftrace_module_init() and before calling do_init_module(), we can suffer from a memory leak. This is because ftrace_module_init() allocates pages to store the locations that ftrace hooks are placed in the module text. If do_init_module() fails, it still calls the MODULE_GOING notifiers which will tell ftrace to do a clean up of the pages it allocated for the module. But if load_module() fails before then, the pages allocated by ftrace_module_init() will never be freed. Call ftrace_release_mod() on the module if load_module() fails before getting to do_init_module().

2016-01-07xen/gntdev: add ioctl for grant copyDavid Vrabel
Add IOCTL_GNTDEV_GRANT_COPY to allow applications to copy between user space buffers and grant references. This interface is similar to the GNTTABOP_copy hypercall ABI except the local buffers are provided using a virtual address (instead of a GFN and offset). To avoid userspace from having to page align its buffers the driver will use two or more ops if required. If the ioctl returns 0, the application must check the status of each segment with the segments status field. If the ioctl returns a -ve error code (EINVAL or EFAULT), the status of individual ops is undefined.

2016-01-07driver-core: platform: Add platform_irq_count()Stephen Boyd
A recent patch added calls to of_irq_count() in the qcom pinctrl drivers and that caused module build failures because of_irq_count() is not an exported symbol. We shouldn't export of_irq_count() to modules because it's an internal OF API that shouldn't be used by drivers. Platform drivers should use platform device APIs instead. Therefore, add a platform_irq_count() API that mirrors the of_irq_count() API so that platform drivers can stay DT agnostic.

2016-01-06cxlflash: Fix to avoid virtual LUN failover failureMatthew R. Ochs
Applications which use virtual LUN's that are backed by a physical LUN over both adapter ports may experience an I/O failure in the event of a link loss (e.g. cable pull). Virtual LUNs may be accessed through one or both ports of the adapter. This access is encoded in the translation entries that comprise the virtual LUN and used by the AFU for load-balancing I/O and handling failover scenarios. In a link loss scenario, even though the AFU is able to maintain connectivity to the LUN, it is up to the application to retry the failed I/O. When applications are unaware of the virtual LUN's underlying topology, they are unable to make a sound decision of when to retry an I/O and therefore are forced to make their reaction to a failed I/O absolute. The result is either a failure to retry I/O or increased latency for scenarios where a retry is pointless. To remedy this scenario, provide feedback back to the application on virtual LUN creation as to which ports the LUN may be accessed. LUN's spanning both ports are candidates for a retry in a presence of an I/O failure. Signed-off-by: Matthew R.

2016-01-06drivers: md: use ktime_get_real_seconds()Deepa Dinamani
get_seconds() API is not y2038 safe on 32 bit systems and the API is deprecated. Replace it with calls to ktime_get_real_seconds() API instead. Change mddev structure types to time64_t accordingly. 32 bit signed timestamps will overflow in the year 2038. Change the user interface mdu_array_info_s structure timestamps: ctime and utime values used in ioctls GET_ARRAY_INFO and SET_ARRAY_INFO to unsigned int. This will extend the field to last until the year 2106. The long term plan is to get rid of ctime and utime values in this structure as this information can be read from the on-disk meta data directly. Clamp the tim64_t timestamps to positive values with a max of U32_MAX when returning from GET_ARRAY_INFO ioctl to accommodate above changes in the data type of timestamps to unsigned int. v0.90 on disk meta data uses u32 for maintaining time stamps. So this will also last until year 2106. Assumption is that the usage of v0.90 will be deprecated by year 2106. Timestamp fields in the on disk meta data for v1.0 version already use 64 bit data types. Remove the truncation of the bits while writing to or reading from these from the disk.

2016-01-05include/uapi/linux/sockios.h: mark SIOCRTMSG unusedxypron.glpk@gmx.de
IOCTL SIOCRTMSG does nothing but return EINVAL. So comment it as unused. SIOCRTMSG is only used in: * net/ipv4/af_inet.c * include/uapi/linux/sockios.h inet_ioctl calls ip_rt_ioctl. ip_rt_ioctl only handles SIOCADDRT and SIOCDELRT and returns -EINVAL otherwise.
