Expand description

Supervisor memory management fence for given address space

The fence orders all reads and writes made to any level of the page tables, but only for the address space identified by integer parameter `asid`.

Accesses to global mappings are not ordered. The fence also invalidates all address-translation cache entries matching the address space identified by integer parameter `asid`, except for entries containing global mappings.
