Subject: [PATCH] kernel/param: consolidate __{start,stop}___param[] in
 <linux/moduleparam.h>

Consolidate the various external const and non-const declarations of
__start___param[] and __stop___param in <linux/moduleparam.h>.  This
requires making a few struct kernel_param pointers in kernel/params.c
const.
