mainlining shenanigans

The RISC-V ISA defines a simple console that is availiable via SBI calls on all systems. The SBI console is designed to be availiable at all times, so while it's most natural to use this as an early printk target it's also possible to use this as the system console when there isn't a better one availiable. This patch adds support for the RISC-V SBI console via the HVC infastructure. It's entirely independent from our early printk support, which results in early boot messages appearing twice over the SBI console. As far as I can tell that's the fault of our early printk support (we should support earlycon) as opposed to this driver. There is one checkpatch.pl warning here: to check the MAINTAINERS file. They're all matched by the "K: riscv" line. Signed-off-by: Palmer Dabbelt <palmer@sifive.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

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.
