Changeset 11369:52df7c56508b --------------------------- x86: fix TLB issue In case we have a 4k page mapping and we will later add a 2M mapping at the same address, we will return the still existing 4k entry. It is unclear to me why this is, but by deleting any entry at the same address with a different size we avoid this problem.
Observed booting FreeBSD amd64; did a manual run to dump the trie to verify a few weeks back.
