Subject: [PATCH 0/4] kallsyms header cleanup

During review of an unrelated patchset, the question was asked why
module.h was included in code that wouldn't be a module and didn't do
anything with modules [1].

The reason is that it uses kallsyms defines, but kallsyms.h doesn't
include module.h, though it should because it uses MODULE_NAME_LEN.
The code in question also didn't include kallsyms.h but relied on
ftrace.h to pull it in.  But ftrace.h no longer contains anything that
needs kallsyms.h, and continues to include it only because other code
expects it to.

This patchset is the start of cleaning all that up.  It also adds
explicit kallsyms.h includes and removes module.h includes for obvious
cases in kernel/trace and lib/, where I happened to be working.

There are a bunch of other files that probably include module.h only
for kallsyms, but I haven't gone through them yet.  I can either
resubmit this patchset after looking at all those, or can submit a
follow-on patchset to this one assuming this is best way to do it...
