Subject: [patch 10/11] uml: add stack addresses to dumps


From: Bodo Stroesser <[email protected]>

Add stack addresses to print of symbols from stack trace.
For stack analysis it's important to have this information.

Signed-off-by: Bodo Stroesser <[email protected]>

For UML, we should also copy the CONFIG_FRAME_POINTER stack walking from i386,
and move the result to sys-i386.

Another note: this should be done for i386 also, if ksymoops does not have
problems.
