For some reason several people have been sending bad patches to fix
compiler warnings in vmcore recently. Here's how it should be done.
Compile-tested only on x86. As noted in the first patch, s390 should
take this conversion a bit further, but I'm not inclined to do that
work myself.

vmcore: Convert copy_oldmem_page() to take an iov_iter
vmcore: Convert __read_vmcore to use an iov_iter
vmcore: Convert read_from_oldmem() to take an iov_iter
