also, while we are materially touching init/initramfs.c, that file has 
collected a few uglies in the past few years, checkpatch --file says:

  total: 7 errors, 7 warnings, 3 checks, 562 lines checked

it has a few other problems as well that can be seen if you look at the 
file. Unused macros:

 /* Diagnostic functions (stubbed out) */
 #define Assert(cond,msg)
 #define Trace(x)
 #define Tracev(x)
 #define Tracevv(x)
 #define Tracec(c,x)
 #define Tracecv(c,x)

 #define STATIC static
 #define INIT __init

lots of no-newline-after-variable-definitions instances:

 {
         int written;
         dry_run = check_only;

no-newline-before-return:

         kfree(header_buf);
         return message;
 }

so it would be nice to start off with a cleanup [strictly no code 
changed] patch.

then it also has an absolutely crazy turn-error-printouts-off hack:

 static __initdata char *message;
 static void __init error(char *x)
 {
         if (!message)
                 message = x;
 }

which is unobvious, 100% unused and should be removed.

those error()s should be pr_debug() perhaps. [this should be a second 
cleanup patch as it changes the code]

Hm?
