I managed to run 32 bits applications , with shared memory using 32 bits
emulation under 64 bit kernel with xenomai 3. (latest git next branch
with 3.18.20 kernel)
The main problem remains with rtnet.
ioctl replies with no such device.
This can be reproduced with rtifconfig 32 and 64 bits version against
rteth0 interface (that is loaded ...).
rtifconfig 64bits works , not 32 bit one.
