Do you mean that CONFIG_HIGHMEM64G is deprecated, should not be used; that all development is for 64-bit only?

Will think about that. I know all my servers are 64-bit capable, will need to check all my desktops.

I find it puzzling that there seems to be a sharp cutoff at 32GB RAM, no problem under but OOM just over; whereas I would have expected lowmem starvation to be gradual, with OOM occuring much sooner with 64GB than with 34GB. Also, the kernel seems capable of reclaiming lowmem, so I wonder why does that fail just over the 32GB threshhold. (Obviously I have no idea what I am talking about.)
