## Summary qemu-rv's S-mode/non-SMP setintstack unconditionally reloaded sp to the top of the per-cpu interrupt stack. A trap taken while already running on that stack rewound sp back to the same address, so the nested trap's frame overwrote the still-live outer trap's frame. Port the bounds check already used by the canonical setintstack in riscv_macros.S: only move sp when it is outside the interrupt stack range. Other vendor chip.h files have the same unconditional-reload pattern and are left for a follow-up. ## Impact RELEASE ## Testing CI -- This is an automated message from the Apache Git Service.
