[BUG] 2.6.3 Slab corruption: errors are triggered when memory exceeds 2GB

[Darren Williams]

On Ia64 Itanium 1 machines with more than 2.5GB of RAM the follwing error is triggered.
 
slab error in check_poison_obj(): cache `size-16384': object was modified after freeing

The machine that triggered the error above is an

i2000 HP workstation
4gb RAM
1gb SWAP

An identical machine with 2.5GB ram produces:

slab error in check_poison_obj(): cache `size-2048': object was modified after freeing

if the amount of RAM is reduced to 2GB or less then the errors do not appear.
