The accessed bit may be set in only some of an L3C superpage's L3
PTEs. However, when pmap_mincore() found an L3C mapping, it reported
the accessed state of the specified L3 PTE only, so mincore(2) could
fail to report MINCORE_REFERENCED for an L3C superpage that had been
accessed. When the accessed bit is not set in the specified entry, use
pmap_load_l3c() to combine the accessed bits from all of the L3C
superpage's L3 PTEs.
