You've used his patches or from origin? That's really not important but
just for curiosity.

Problem with patches vs public repo is that they lack 'origin'.
You don't know what version you need to apply them, you can not reliably
track changes etc...

So patchset is changing... Another argument to settle it in some repo.

Heh, since you are working on it - you are EMC developer :)

If there is no other way to get them - yes.
Is it possible for you (or maybe Michael) to setup repository with your patchset
somewhere? github (or gitourious) are easy to start with and allow you to commit
anything you want without threat of breaking main emc2 repository. But will
provide
others with good point to track your changes, review and maybe merge to
mainline.
If it's not an option somebody may merge theese patches for you but that will do
more harm then good -- you won't be able to control that process and for example
if merger has no linux-rt testbed may introduce untested bugs.

It depends on complexity of changes and probably should live in separate branch
for a while.
