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:

The majority of the s390 patches for the 4.12 merge window:

* Included are three merges for KVM/s390 with changes for vfio-ccw and cpacf.
The patches are included in the KVM tree as well, let git sort it out.

* Add the new 'trng' random number generator

* Provide the secure key verification API for the pkey interface

* Introduce the z13 cpu counters to perf

* Add a new system call to set up the guarded storage facility

* Simplify TASK_SIZE and arch_get_unmapped_area

* Export the raw STSI data related to CPU topology to user space

* And the usual churn of bug-fixes and cleanups.

On my test pull today there has been a small merge conflict in
arch/s390/Kconfig. HAVE_ARCH_HARDENED_USERCOPY got removed by
git commit 2fefc97b2180518b from Al and HAVE_ARCH_EARLY_PFN_TO_NID
is removed by a patch from Heiko in this pull request.
