s390/sysinfo: add and display licensed internal code identifier

2018-02-02T09:47:15Z

With z14, the store system information instruction provides an licensed internal code identifier. Display it in /proc/sysinfo. For more information, see the z/Architecture Principles of Operation.

s390: include: Remove redundant license text

2017-11-24T14:37:22Z

Now that the SPDX tag is in all arch/s390/include/ 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.

s390: add SPDX identifiers to the remaining files

2017-11-24T14:37:19Z

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the remaining arch/s390/ 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.

Add the store-hypervisor-information code into features using a tip branch for parallel merging into the KVM tree.

s390/sthyi: reorganize sthyi implementation

As we need to support sthyi instruction on LPAR too, move the common code to kernel part and kvm related code to intercept.c for better reuse. Signed-off-by: QingFeng Hao Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

s390/topology: add detection of dedicated vs shared CPUs

2017-09-28T05:29:43Z

The topology information returned by STSI 15.x.x contains a flag if the CPUs of a topology-list are dedicated or shared. Make this information available if the machine provides topology information. Signed-off-by: Martin Schwidefsky

s390/sysinfo,topology: provide raw stsi 15,1,x data via debugfs

2017-03-22T07:29:15Z

Provide the raw stsi 15,1,x data contents via debugfs. This makes it much easier to debug unexpected scheduling domains on machines that provide cpu topology information. Therefore this file adds a new 's390/stsi' debugfs directory with a file for each possible topology nesting level that is allowed by the architecture. The files will be created regardless if the machine supports all, or any, level. If a level is not supported, or no data is available, user space can recognize this with a -EINVAL error code when trying to read such data. In addition a 'topology' symlink is created that points to the file that contains the data that is used to create the scheduling domains.

s390/topology: get rid of core mask array

2017-03-22T07:29:07Z

Use a single long value instead of a single element array to represent the core mask. The array is a leftover from 32/31 bit code so we were able to use bitops helper functions. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky
