tmpfs size restriction

I'm facing an issue with tmpfs mounts on PowerPC (mpc83xx specifically).
After "mount -t tmpfs tmpfs /tmp -o size=16m" I can fill the machine's mem
(512MiB) until oom becomes active.
I can't see this on any other machine (x86/ARM) I have access to.
There's always a "no space left on device" message as soon as size specified is
kernel versions available are v18.104.22.168 and v22.214.171.124 showing the same
I'd expect the kernel to limit available tmpfs size to 50% of physical memory
Any ideas what might be wrong ?
