This fixes calculating the key bits (KP and KS) in the SLB VSID for kernel
mappings.
I'm not CCing this to stable as there are no uses of this currently.

The cxl kernel API will allow drivers other than cxl to export a file
descriptor which has the same userspace API. These file descriptors will be
able to be used against libcxl.
This exports those file ops for use by other drivers.

When we release the device, we should also invalidate the default context.
With this cxl_get_context() will return null after removal.

The Debian powerpc little endian architecture is called ppc64le. This
is the default architecture used by Ubuntu for powerpc.
The below checks the kernel config to see if we are compiling little
endian and sets the Debian arch appropriately.

This add support for the Coherent Accelerator (cxl) attached to POWER8
processors. This coherent accelerator interface is designed to allow the
coherent connection of FPGA based accelerators (and other devices) to a POWER
systems.
IBM refers to this as the Coherent Accelerator Processor Interface

This will be used by some of the cxl PCIe code later.

This defines structs and magic numbers required for userspace to interact with
the kernel cxl driver via /dev/cxl/afu0.0.
It adds this header file Kbuild so it's exported when doing make
