This configuration variable will be used to build the support for VMA locking during page fault handling. This is enabled by default on supported architectures with SMP and MMU set. 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? Thanks, Davidlohr
