The functions are __init because they're currently only needed during boot, and using __init allows the text to be freed once it's over, saving some memory. So this change, in isolation, doesn't make sense. If there were an enhancement you were thinking of making, this patch could then be bundled with it so the change is made only when it's used. However, there's still work that needs to be merged before padata_do_multithreaded can be called after boot. See the parts about priority adjustments (MAX_NICE/renicing) and concurrency limits in this branch https://oss.oracle.com/git/gitweb.cgi?p=linux-dmjordan.git;a=shortlog;h=refs/heads/padata-mt-wip-v0.5 and the ktask discussions from linux-mm/lkml where concerns about these issues were raised. I plan to post these parts fairly soon and can include you if you want.
