Thanks for the patch. There's nothing dangerous as kmemleak takes care
of not using the __init functions after it was initialised but I
couldn't find a way to free these functions/data and also avoid the
warning.

Anyway, that's fine as an interim patch but I think I'll just allocate
some pages dynamically for the early logging buffer so that we can free
them once initialised. I'll update the kmemleak branch sometime this
week.

Thanks.
