[PATCH] Fix for "mod -S" causes symbols to be incorrect
by Lianbo Jiang
Currently, the "mod -S" command may cause that the "bt/sym" commands
incorrectly translate the kernel module virtual address to symbol names,
if a kernel module contains a per-cpu section, this was reported on
PPC64 kernel.
Without the patch:

[PATCH] maple_tree: add support for maple_tree.c output to respect the global radix and per-command -x/d flags
by Sterling Alexander
The commands that generate maple tree output do not currently respect the
global radix setting, nor do they respect the -x output flag. This
patch aims to fix this inconsistency, so that the output commands
respect both the global radix setting as well as the per-command -x/d
flags.
