Hi Nicholas,

There are two cases outside the normal address space management
where a CPU's local TLB is to be flushed:
1. Host boot; in case something has left stale entries in the
TLB (e.g., kexec).
2. Machine check; to clean corrupted TLB entries.
CPU state restore from deep idle states also flush
