Without this, only the crash frame's window is spilled to the stack; all deeper call frames remain in the register file and are absent from the core's memory segments. Stack unwinding fails past the first DWARF step because the callers' register save areas contain stale/garbage data. The real kernel calls flush_all_user_windows() at the top of do_coredump(). Mirror that via a weak target_flush_windows() hook called from dump_core_and_abort(), with the SPARC override calling the existing flush_windows() in cpu_loop.c.
