This provokes early boot failure (before the # console is active). # # As it is not necessary to do this verification that early, this # patch moves the test into patch_instruction() instead of # __patch_instruction(). # # This modification also has the advantage of avoiding unnecessary # remappings. # # Fixes: 51c3c62b58b3 ("powerpc: Avoid code patching freed init sections") # Cc:
