mainlining shenanigans

The warning message "READ LOG DMA EXT failed, trying unqueued" in ata_read_log_page() as well as the macro name ATA_HORKAGE_NO_NCQ_LOG are confusing: the command READ LOG DMA EXT is not an queued NCQ command unless it is encapsulated in a RECEIVE FPDMA QUEUED command. From ACS-4 READ LOG DMA EXT description: "The device processes the READ LOG DMA EXT command in the NCQ feature set environment (see 4.13.6) if the READ LOG DMA EXT command is encapsulated in a RECEIVE FPDMA QUEUED command (see 7.30) with the inputs encapsulated as shown in 7.23.6." To avoid confusion, fix the warning messsage to mention switching to PIO and not "unqueued" and rename the macro ATA_HORKAGE_NO_NCQ_LOG to ATA_HORKAGE_NO_DMA_LOG.

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.
