Nicholas Piggin c28573744b powerpc/64s: Make hash MMU support configurable 
This adds Kconfig selection which allows 64s hash MMU support to be
disabled. It can be disabled if radix support is enabled, the minimum
supported CPU type is POWER9 (or higher), and KVM is not selected.

IBM Coherent Accelerator (CXL) compatible devices

config CXL tristate "Support for IBM Coherent Accelerators (CXL)" depends on PPC_POWERNV && PCI_MSI && EEH select CXL_BASE default m help Select this option to enable driver support for IBM Coherent Accelerators (CXL). CXL is otherwise known as Coherent Accelerator Processor Interface (CAPI). CAPI allows accelerators in FPGAs to be coherently attached to a CPU via an MMU. This driver enables userspace programs to access these accelerators via /dev/cxl/afuM.N devices.

  CAPI adapters are found in POWER8 based systems.
