  "message": "linux-user/sparc: flush register windows before core dump\n\nWithout this, only the crash frame\u0027s window is spilled to the\nstack; all deeper call frames remain in the register file and\nare absent from the core\u0027s memory segments. Stack unwinding\nfails past the first DWARF step because the callers\u0027 register\nsave areas contain stale/garbage data.\n\nThe real kernel calls flush_all_user_windows() at the top of\ndo_coredump(). Mirror that via a weak target_flush_windows()\nhook called from dump_core_and_abort(), with the SPARC override\ncalling the existing flush_windows() in cpu_loop.c.\n\nSigned-off-by: Matt Turner \u003cmattst88@gmail.com\u003e\nCc: Mark Cave-Ayland \u003cmark.cave-ayland@ilande.co.uk\u003e\nSigned-off-by: Helge Deller \u003cdeller@gmx.de\u003e\n",
