s390: kernel: add SPDX identifiers to the remaining files

2017-11-24T14:37:12Z

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

s390/cputime: simplify account_system_index_scaled

2017-06-12T14:25:57Z

The account_system_index_scaled gets two cputime values, a raw value derived from CPU timer deltas and a scaled value. The scaled value is always calculated from the raw value, the code can be simplified by moving the scale_vtime call into account_system_index_scaled. Signed-off-by: Martin Schwidefsky

sched/headers: Prepare to move cputime functionality from into

2017-03-02T07:42:39Z

Introduce a trivial, mostly empty header to prepare for the moving of cputime functionality out of sched.h. Update all code that relies on these facilities.

s390/cputime: remove last traces of cputime_t

2017-03-01T08:59:27Z

The cputime_t type is a thing of the past, replace the last occurences of the type in the s390 code with a simple u64. Signed-off-by: Martin Schwidefsky

sched/cputime: Convert task/group cputime to nsecs

2017-02-01T08:13:49Z

Now that most cputime readers use the transition API which return the task cputime in old style cputime_t, we can safely store the cputime in nsecs. This will eventually make cputime statistics less opaque and more granular. Back and forth convertions between cputime_t and nsecs in order to deal with cputime_t random granularity won't be needed anymore.
