Commit3840ed9548("tty: goldfish: Implement support for kernel 'earlycon' parameter") breaks an allmodconfig config on x86: | LD vmlinux.o | MODPOST vmlinux.o |drivers/tty/serial/earlycon.o: In function `parse_options': |drivers/tty/serial/earlycon.c:97: undefined reference to `uart_parse_earlycon' |Makefile:1005: recipe for target 'vmlinux' failed earlycon.c::parse_options() invokes uart_parse_earlycon() from serial_core.c which is compiled=m because GOLDFISH_TTY itself (and most others) are =m. To avoid that, I'm adding the _CONSOLE config option which is selected if the GOLDFISH module itself is =y since it doesn't need the early bits for the =m case (other drivers do the same dance). The alternative would be to move uart_parse_earlycon() from serial_core.c to earlycon.c (we don't have that many users of that function).

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.
