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 *.
