We have a whole pile of unused code to maintain the ACOP register, allocate coprocessor PIDs and handle ACOP faults. This mechanism was used for the HFI adapter on POWER7 which is dead and gone and whose driver never went upstream. It was used on some A2 core based stuff that also never saw the light of day. Take out all that code. There is still some POWER8 coprocessor code that uses icswx but it's kernel only and thus doesn't use any of that infrastructure.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
