Is this available as a patch, or preferably as a compilation option to the standard kernel?
The ASIC tools that we use wants all the memory they can grab, and the extra few hundred megs can sometimes be _very_ critical. On Solaris, Synopsys' Design Compiler can allocate 3.8Gig and we've hit that limit hard when working with toplevel netlists and SDF databases.
