Currently, when booting a kernel with DMI support on a platform that has no DMI tables, the following output is emitted into the kernel log: [ 0.128818] DMI not present or invalid. ... [ 1.306659] dmi: Firmware registration failed. ... [ 2.908681] dmi-sysfs: dmi entry is absent. The first one is a pr_info(), but the subsequent ones are pr_err()s that complain about a condition that is not really an error to begin with. So let's clean this up, and give up silently if dma_available is not set.

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.
