Subject: [251/264] crypto: cryptd - Use subsys_initcall to prevent races with aesni

3.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Herbert Xu <herbert@...dor.apana.org.au>

commit b2bac6acf86d05d8af0499f37d91ecac15722803 upstream.

As cryptd is depeneded on by other algorithms such as aesni-intel,
it needs to be registered before them.  When everything is built
as modules, this occurs naturally.  However, for this to work when
they are built-in, we need to use subsys_initcall in cryptd.
