Add abort support for aens. Commonized the op abort to apply to aen or real ios (caused some reorg/routine movement). Abort path sets termination flag in prep for next patch that will be watching i/o abort completion before proceeding with controller teardown. Now that we're aborting aens, the "exit" code that simply cleared out their context no longer applies. Also clarified how we detect an AEN vs a normal io - by a flag, not by whether a rq exists or the a rqno is out of range. Note: saw some interesting cases where if the queues are stopped and we're waiting for the aborts, the core layer can call the complete_rq callback for the io. So the io completion synchronizes link side completion with possible blk layer completion under error.

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.
