This happened with xtensa-allmodconfig. I compiled my own xtensa-allmodconfig kernel, and it happens there, too. If I'm not mistaken, the hex address between parentheses should match the "from" function, right? After disassembly ("xtensa-linux-objdump -D vmlinux"), the addresses didn't seem to match the function names at all. So it may be an issue with the toolchain?
