/proc/kcore size

Hi all...

To the request of one of my users, I installed the 'hinv' program (1.4pre1) by
Larry McVoy.

Problem: it detects the memory amount in the box by stat'ing /proc/kcore.
Thats not the problem, but that the box has 1Gb of memory, and kcore is just
896Mb big.

Kernel is built with 4Gb support:

annwn:/proc# free
total used free shared buffers cached
Mem: 1033172 1017772 15400 0 164792 556416
-/+ buffers/cache: 296564 736608
Swap: 1951856 8 1951848

annwn:/proc# hinv
Main memory size: 896 Mbytes
...

annwn:/proc# ll /proc/kcore
-r-------- 1 root root 939528192 Jan 12 10:02 /proc/kcore

Exactly the same as a box that has _really_ 896 Mb:

werewolf:/proc# ll kcore
-r-------- 1 root root 939528192 Jan 12 10:02 kcore

werewolf:/proc# free
total used free shared buffers cached
Mem: 905012 276008 629004 0 27268 109344
-/+ buffers/cache: 139396 765616
Swap: 345356 0 345356

BUG ?

TIA
