2017-11-24s390: drivers: Remove redundant license textGreg Kroah-Hartman1-4/+0
Now that the SPDX tag is in all drivers/s390/ files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

2017-11-24s390: virtio: add SPDX identifiers to the remaining filesGreg Kroah-Hartman1-0/+1
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/s390/virtio/ files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

2017-09-29s390/virtio: remove the old KVM virtio transportThomas Huth1-3/+0
There is no recent user space application available anymore which still supports this old virtio transport. Additionally, commit 3b2fbb3f06ef ("virtio/s390: deprecate old transport") introduced a deprecation message in the driver, and apparently nobody complained so far that it is still required. So let's simply remove it.

2016-08-09virtio/s390: deprecate old transportCornelia Huck1-1/+5
There only ever have been two host implementations of the old s390-virtio (pre-ccw) transport: the experimental kuli userspace, and qemu. As qemu switched its default to ccw with 2.4 (with most users having used ccw well before that) and removed the old transport entirely in 2.6, s390-virtio probably hasn't been in active use for quite some time and is therefore likely to bitrot. Let's start the slow march towards removing the code by deprecating it. Note that this also deprecates the early virtio console code, which has been causing trouble in the guest without being wired up in any relevant hypervisor code.
