Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky:
"Among the traditional bug fixes and cleanups are some improvements:
- A tool to generated the facility lists, generating the bit fields
by hand has been a source of bugs in the past
- The spinlock loop is reordered to avoid bursts of hypervisor calls
- Add support for the open-for-business interface to the service
element
- The get_cpu call is added to the vdso
- A set of tracepoints is defined for the common I/O layer
- The deprecated sclp_cpi module is removed
- Update default configuration"
