These were discussed at UDS:

comparing 64/64 64/32 32/32 kernel/userspace for various tasks, memory
usage, power consumption, and duration where approporiate.

What I can deduce from those is that 32-bit userspace definitely uses
15-20% less memory. power consumption was the same within 1% for most
tests, but 10% and 4% worse on 32bit for 2 tests (no idea why). 

Principal hats:  Linaro, Emdebian, Wookware, Balloonboard, ARM
