This configuration variable will be used to build the support for VMA

This is enabled by default on supported architectures with SMP and MMU

The architecture support is needed since the page fault handler is called
from the architecture's page faulting code which needs modifications to
handle faults under VMA lock.
I don't think that per-vma locking should be something that is
user-configurable.
It should just be depdendant on the arch. So maybe just remove
CONFIG_PER_VMA_LOCK?
