This should help us to: - More easily add or remove machine initialization arguments without having to change every single machine init function; - More easily make mechanical changes involving the machine init functions in the future; - Let machine initialization forward the init arguments to other functions more easily. This change was half-mechanical process: first the struct was added with the local ram_size, boot_device, kernel_*, initrd_*, and cpu_model local variable initialization to all functions. Then the compiler helped me locate the local variables that are unused, so they could be removed. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
