I don't know where this ALIGN() came from, but I am hesitant to remove
it until I am sure it is safe to do so.
For both x86 and arm, .initcall will take a little more work to
disentangle, although I do intend to make it happen.
On arm, .init.proc.info is an array of 32byte elements. Looking at its
contents, it should be constant, and probably wants 4 byte alignment as
opposed to 32.

Will do.
