I assume the warning was for `calltime'? Maybe other things? Please,
remove all doubt and always quote the compiler output in the changelog.

Also please mention the compiler version - it looks like this is a new
warning. It's not a false positive either - the compiler doesn't know
that initcall_debug's value never changes.

The patch doesn't apply to linux-next because someone went on a great
tromp through do_one_initcall() so could you please redo the patch
against linux-next?

I suggest that you not inline do_one_initcall_debug() - the compiler
will do that anwyay.

And if you're feeling keen, please do a separate patch which marks
do_one_initcall() and do_one_initcall_debug() with __init_or_module -
we don't need to leave that code in memory after bootup if
CONFIG_MODULES=n.

Thanks.
