how many "contexts" are there?

[Robert P. J. Day]

  the standard explanation of context related to linux is that there
are three "contexts" one can be in at any time:

  * user context
  * kernel, process context
  * kernel, interrupt context

but that's clearly(?) an incomplete (or not refined enough) list,
since it doesn't include kernel threads, and a quick google showed
this:

http://stackoverflow.com/questions/9389688/in-what-context-kernel-thread-runs-in-linux

  so is there a more refined or up-to-date list of contexts which
explains them fairly well, including the subtle distinctions?  thanks.
