Expand description

Supervisor memory management fence for given virtual address

The fence orders only reads and writes made to leaf page table entries corresponding to the virtual address in parameter `vaddr`, for all address spaces. The fence also invalidates all address-translation cache entries that contain leaf page table entries corresponding to the virtual address in parameter `vaddr`, for all address spaces.
