[PATCH] sparc64: add function save_stack_trace_tsk()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi

Current -next does not build on sparc64:
  LD      .tmp_vmlinux1
  fs/built-in.o: In function `proc_pid_stack':
  /home/alexb/linux-2.6/fs/proc/base.c:360: undefined reference to
  `save_stack_trace_tsk'

---

  Add function save_stack_trace_tsk() on sparc64.
