Make show_regs() to dump the stack to improve riscv crash report,
and also fix the wrong value when stack unwind if FRAME_POINTER
enabled.

Chen Huang (1):
  riscv/stacktrace: Fix stack output without ra on the stack top

Kefeng Wang (2):
  riscv: Add dump stack in show_regs
  riscv: Improve __show_regs
