We have some function implementation under some arch does nothing.
We can mark it with weak attributes to improve.
1. arch_init_kprobes in kprobes
2. arch_uprobe_exception_notify in uprobes

Yipeng Zou (2):
  kprobes: make arch_init_kprobes as weak
  uprobes: make arch_uprobe_exception_notify as weak
