Merge tag 'powerpc-4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman: "Highlights include:
- Larger virtual address space on 64-bit server CPUs. By default we use a 128TB virtual address space, but a process can request access to the full 512TB by passing a hint to mmap().
- Support for the new Power9 "XIVE" interrupt controller.
- TLB flushing optimisations for the radix MMU on Power9.
- Support for CAPI cards on Power9, using the "Coherent Accelerator Interface Architecture 2.0".
- The ability to configure the mmap randomisation limits at build and runtime.
- Several small fixes and cleanups to the kprobes code, as well as support for KPROBES_ON_FTRACE.
- Major improvements to handling of system reset interrupts, correctly treating them as NMIs, giving them a dedicated stack and using a new hypervisor call to trigger them, all of which should aid debugging and robustness.
- Many fixes and other minor enhancements.

powerpc/xive: Native exploitation of the XIVE interrupt controller
The XIVE interrupt controller is the new interrupt controller found in POWER9. It supports advanced virtualization capabilities among other things.
Currently we use a set of firmware calls that simulate the old "XICS" interrupt controller but this is fairly inefficient.
This adds the framework for using XIVE along with a native backend which OPAL for configuration. Later, a backend allowing the use in a KVM or PowerVM guest will also be provided.
This disables some fast path for interrupts in KVM when XIVE is enabled as these rely on the firmware emulation code which is no longer available when the XIVE is used natively by Linux.
A latter patch will make KVM also directly exploit the XIVE, thus recovering the lost performance (and more).
