Merge tag 'powerpc-4.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman: "Highlights include: - Support for STRICT_KERNEL_RWX on 64-bit server CPUs. - Platform support for FSP2 (476fpe) board - Enable ZONE_DEVICE on 64-bit server CPUs. - Generic & powerpc spin loop primitives to optimise busy waiting - Convert VDSO update function to use new update_vsyscall() interface - Optimisations to hypercall/syscall/context-switch paths - Improvements to the CPU idle code on Power8 and Power9. As well as many other fixes and improvements.
