Browse Source 
Pull s390 updates from Martin Schwidefsky:

 - Support for kernel address space layout randomization

 - Add support for kernel image signature verification

 - Convert s390 to the generic get_user_pages_fast code

 - Convert s390 to the stack unwind API analog to x86

 - Add support for CPU directed interrupts for PCI devices

 - Provide support for MIO instructions to the PCI base layer, this will
   allow the use of direct PCI mappings in user space code

 - Add the basic KVM guest ultravisor interface for protected VMs

 - Add AT_HWCAP bits for several new hardware capabilities

 - Update the CPU measurement facility counter definitions to SVN 6

 - Arnds cleanup patches for his quest to get LLVM compiles working

 - A vfio-ccw update with bug fixes and support for halt and clear

 - Improvements for the hardware TRNG code

 - Another round of cleanup for the QDIO layer

 - Numerous cleanups and bug fixes
