License cleanup: add SPDX license identifier to uapi header files with a license Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

net/hsr: Add support for the High-availability Seamless Redundancy protocol (HSRv0) High-availability Seamless Redundancy ("HSR") provides instant failover redundancy for Ethernet networks. It requires a special network topology where all nodes are connected in a ring (each node having two physical network interfaces). It is suited for applications that demand high availability and very short reaction time. HSR acts on the Ethernet layer, using a registered Ethernet protocol type to send special HSR frames in both directions over the ring. The driver creates virtual network interfaces that can be used just like any ordinary Linux network interface, for IP/TCP/UDP traffic etc. All nodes in the network ring must be HSR capable. This code is a "best effort" to comply with the HSR standard as described in IEC 62439-3:2010 (HSRv0). Signed-off-by: Arvid Brodin <arvid.brodin@xdin.com> Signed-off-by: David S.
