The patch basically looks fine to me, except that I'd really like to
prefer to have it split up into one patch that does the pt_regs fixes
and one that does the debug enhancements.  And while you're at it,
please use something a bit more concise than UNW_DEBUG_PRINT
(something like DPRINT or UNW_DPRINT should be sufficient).
