It seems like a lot of fuss for a small problem.  But this:

--- a/init/main.c~init-mainc-wrap-long-kernel-cmdline-when-printing-to-logs-fix
+++ a/init/main.c
@@ -944,7 +944,7 @@ static void __init early_numa_node_init(
  *   Kernel command line: jumps over the \
  *   Kernel command line: lazy dog."
  */
-static void print_kernel_cmdline(const char *cmdline)
+static void __init print_kernel_cmdline(const char *cmdline)
 {
 	size_t len;
 
_

will make it a whole lot more palatable, no?
