Not able to mlock

Hi all!,

I am not able to mlock more than half of the memory available. I am
working on ARM processor in which
64 MB of SDRAM memory is available. But I am not able to mlock more
than 32 MB. If I am trying to allocate more than 32 MB, it return
an ENOMEM error. Can any one suggest me why this is happening and what
is the way to mlock more than 32 MB?
Please let me know, do I need to set the limit for mlock in kernel? If
so, where do I set the limit for mlock?

Thanks and Regards,
P.R.Hariram
