Hi YiZiRui,

if this is really the case, this would constitute a bug - VOLK kernels
should work on 32bit machines too, although there might be
instructions that only appear on CPU's that support 64bit anyway.

However, nowadays it surprises me that people install 32bit linuxes on
modern machines at all; having more than 3.2GB of RAM is rather usual
today :) but not (natively) possible with 32bit OSses.

With respect to make test fails: Bugs are fixed on a daily basis, and
a lot of things are happening in VOLK right now, so the fails on a
64bit machine might not really be os-dependent...

Greetings,
Marcus
