Sorry. I know how to use addr2line. But it is not what I'm looking for.
For example, with i386 kernel, it is easy to find c017e7a5 belong to
function get_user.
x86]$ vi /hack/linux-3.12.6/Documentation/x86/exception-tables.txt
.

Hi, all
I build linux-3.12.6 uml with default configure.
tar -jxf linux-3.12.6.tar.bz2
cd linux-3.12.6
make ARCH=um defconfig
make ARCH=um linux
I'm confused about the exception table of the uml kernel.
$ objdump --full-contents --section=__ex_table linux
linux: file format elf32-i386
C
let me answer your second question.
I did this analysis with kernel linux-3.12.6:
1) make ARCH=um cscope
2) search functions which called 'clone'
File FunctionLine
0 ubd_user.c start_io_thread 43 pid = clone(io_thread, (void *) sp,
CLONE_FILES |
