I ended up with a file not found error and it's asking for which file to patch. I'm assuming this is a conflict. Do I need to modify the grsec patch file to remove conflicts, or do I have to take the default Linux kernel and work on that one?
Any help is appreciated, thanks.

Perhaps you used the wrong -p or --strip option?
