sys/arch/powerpc64/powerpc64: pmap.c
Log message:
Even though the PowerISA indicates that hardware should update reference
and change bits in the page table entries that doesn't seem to happen
reliably on the POWER9 CPU I'm looking at. So make our pmap not depend
on this and emulate these bits instead.
As far as I can determine Linux doesn't rely on the hardware bits either.
