Nothing to worry about. It's normal and should be there, it represents the entire virtual address space for your system. It can be used for debugging
the kernel while it is running.
It's a virtual file, In fact, everything in /proc
is a virtual file. They don't physically exist on your disk.
On my debian wheezy desktop, running
# ls -lh /proc/kcore
...shows that it is 128TB in size (i only have a 280GB disk).
128TB is the limit for total virtual RAM on x86_64 machines, which is why it shows up as that size for me.
