When core_kernel_text() is used to determine whether an address on a task's stack trace is a kernel text address, it incorrectly returns false for early text addresses for the head code between the _text and _stext markers. Head code is text code too, so mark it as such. This seems to match the intent of other users of the _stext symbol, and it also seems consistent with what other architectures are already doing.
