Mostly from sparc64, where it's not a myth. That's why Linux on sparc64
(and IIRC, Solaris too) uses a 32-bit userland[1], even when running
with a 64-bit kernel. Certain key apps will be 64-bit (e.g., databases,
and other apps that need access to large amounts of memory), but the
rest of the system is 32-bit, IIRC mostly to reduce cache pressure.
However, on other architectures, for example amd64, the same isn't
true, so the whole of userland tends to be 64-bit.

    couple of years, so this might have changed by now.
