We need to have backtrace() / print_backtrace() et al. working from
contexts without a kernel-supplied pt_regs to start from. This is
needed for e.g. markers.
See also bug #6580, bug #5085.

In the short term, it may be sufficient to jump over to the
kernel's show_stack() routine (if configured & available --
runtime/autoconf time).
For the longer term, a facility for filling in a pt_regs struct
on demand would be nice to find and use.
