Hi,

When I use GDB to debug a Kernel that running on the QEMU.  The GDB
cannot get the debug message from lkm.

I just can load this debug message with my hand:
1. Get the right module from modules.  It need parse the struct list.
2. p module->module_core get the mod address.
3. add-symbol-file mode.ko address

Do we have some easy way to handle it?

Thanks,
Hui
