Subject: [cryptd] BUG: Bad page state in process cryptomgr_test pfn:0e0d0
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is

crypto: cryptd - Use subsys_initcall to prevent races with aesni
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.
