Subject: [GIT PULL] s390 patches for 4.5 merge window
Hi Linus,
please pull from the 'for-linus' branch of
git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git for-linus
to receive the following updates:
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
There is a trivial merge conflict with a patch from Al, I hope it
is not too much of a hassle to fix it.
