/*
* Originally we used small TLB pages for kernel data and grouped some
- * things together as "write once", enforcing the property at the end
+ * things together as ro-after-init, enforcing the property at the end
* of initialization by making those pages read-only and non-coherent.
* This allowed better cache utilization since cache inclusion did not
* need to be maintained. However, to do this requires an extra TLB
* entry, which on balance is more of a performance hit than the
* non-coherence is a performance gain, so we now just make "read
- * mostly" and "write once" be synonyms. We keep the attribute
+ * mostly" and "ro-after-init" be synonyms. We keep the attribute
* separate in case we change our minds at a future date.
