Revision 29b6cd794e73eea7600541d06288a09861ffecb0 authored by Masami Hiramatsu on 18 December 2007, 17:05:58 UTC, committed by Ingo Molnar on 18 December 2007, 17:05:58 UTC 
x86: jprobe bugfix
 
jprobe for x86-64 may cause kernel page fault when the jprobe_return()
is called from incorrect function.

- Use jprobe_saved_regs instead getting it from stack.
  (Especially on x86-64, it may get incorrect data, because
   pt_regs can not be get by using container_of(rsp))
- Change the type of stack pointer to unsigned long *.
