The driver special cases certain things for command issue, depending on whether it's an internal command or not. Make the internal commands use the regular infrastructure for issuing IO. Since this is an 8-group souped up AHCI variant, we have to deal with NCQ vs non-queueable commands. Do this from the queue_rq handler, by backing off unless the drive is idle.

README
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.
