  "message": "powerpc/kprobes: Dereference function pointers only if the address does not belong to kernel text\n\nThis makes the changes introduced in commit 83e840c770f2c5\n(\"powerpc64/elfv1: Only dereference function descriptor for non-text\nsymbols\") to be specific to the kprobe subsystem.\n\nWe previously changed ppc_function_entry() to always check the provided\naddress to confirm if it needed to be dereferenced. This is actually\nonly an issue for kprobe blacklisted asm labels (through use of\n_ASM_NOKPROBE_SYMBOL) and can cause other issues with ftrace. Also, the\nadditional checks are not really necessary for our other uses.\n\nAs such, move this check to the kprobes subsystem.\n\nFixes: 83e840c770f2 (\"powerpc64/elfv1: Only dereference function descriptor for non-text symbols\")\nCc: stable@vger.kernel.org # v4.13+\nSigned-off-by: Naveen N.
