Hi all,

soryy for such ugly subject line, but I already sent this patch=20
to LKML and didn't get any reply.

Patch adds __init_msg (and friends) macro that places its argument=20
(string constant) into corresponding .data.init section and returns
pointer to it. The goal of this patch is to allow constructions like this:

static void __init foo(void)
{
printk(__init_msg(KERN_INFO "Some random long message "
"going to .data.init and then to bit bucket\n"));
}

I hope this patch can save some memory and will be usefull :))

Best regards.
