Protection by rtems_interrupt_disable() is incompatible with SMP build. Actual page table entries manipulation function does not need locking and disabling cache and can be run concurrently even on multiple CPUs as long as changes do not modify same region. If the function is called from more threads/CPUs to modify same region with different mapping options concurrently then there is problem at another level of virtual address space management and has to be solved by mutex or other locking at that level.
