Help text

If you enabled support for /proc file system then the file /proc/kcore will contain the kernel core image in ELF format. This can be used in gdb:

$ cd /usr/src/linux ; gdb vmlinux /proc/kcore

This is especially useful if you have compiled the kernel with the "-g" option to preserve debugging information. It is mainly used for examining kernel data structures on the live kernel.
