Dunno of arm. We're talking about > architectures needing discontigmem, 99% percent of users doesn't need > discontigmem in the first place, you never need discontigmem in x86 and That's not true. We use discontigmem on the NUMA-Q boxes for NUMA support. In some memory models, they're also really discontigous memory machines. At the moment I use the contig memory model (so we only use discontig for NUMA support) but I may need to change that in the future. M.
