Subject: [PATCH v3 0/3] jump_label: Robustify jump label patching

v3:
- Make init_kernel_text() global
- Use braces in multi-line 'for' statements

v2:
- Refine the warning so that it doesn't warn about __init entries
- (Do so by explicitly disabling __init entries)
- Drop v1 patches which removed __init tracepoints

Josh Poimboeuf (3):
  jump_label: Explicitly disable jump labels in __init code
  jump_label: Warn on failed jump_label patch
  extable: Make init_kernel_text() global
