[Xen-devel] [Patch v3 0/4] Xen stack trace printing improvements

This series consists of improvements to Xen's ability to print traces of its
own stack, and specifically for the stack overflow case to be able to use
frame pointers in a debug build.

I have dev tested the series in debug and non-debug cases, with and without
memory guards, and I believe that all the stack traces look correct (given the
available information Xen has), and that the boundaries are now correct. This
series has had a substantial rebase on top of the %pS series.

George: Regarding the 4.4 code, I would like to argue this as a bugfix rather
than feature, therefore being exempt from the freeze at the moment.
