Merge tag 's390-6.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Vasily Gorbik:

 - Make use of the IBM z16 processor activity instrumentation facility
   extension to count neural network processor assist operations: add a
   new PMU device driver so that perf can make use of this.

 - Rework memcpy_real() to avoid DAT-off mode.

 - Rework absolute lowcore access code.

 - Various small fixes and improvements all over the code.
