You don't want to do that :) You're starving other GFP_ATOMIC processes, and will increase system failures due to lack of memory... even though there may be plenty outside the emergency pools.
One option is to create a background kernel thread (via schedule_task or schedule_work, depending on your kernel version) that allocates memory which your tasklet then takes.
