Mark Johnston 53a2985c43 pkru: Fix handling of 1GB largepage mappings 
pmap_pkru_update_range() did not handle the case where a PDPE has PG_PS
set.  More generally, the SET_PKRU and CLEAR_PKRU sysarch
implementations did not check whether the request covers a "boundary" vm
map entry.  Fix this, add the missing PG_PS test, and add some tests.
