This set is based on mmotm's kcore patch stack.
So, just for discussing. 

  [1/3] ... clean up (tiny bug fix)
  [2/3] ... show size of /proc/kcore
  [3/3] ... update kcore size at memory hotplug.

After patches, /proc/kcore's size is as following.
==
[kamezawa@bluextal mmotm-2.6.31-Sep14]$ ls -l /proc/kcore
-r-------- 1 root root 140737486266368 2009-09-17 11:53 /proc/kcore
[kamezawa@bluextal mmotm-2.6.31-Sep14]$

I'm not sure how this value is useful...but..hmm..better than zero ?
(The reason of very big value is because vmalloc area is too large.)


Thanks,
-Kame
