Linus Torvalds 4a692ae360 - Flush *all* mappings from the TLB after switching to the trampoline 
pagetable to prevent any stale entries' presence
 
 - Flush global mappings from the TLB, in addition to the CR3-write,
 after switching off of the trampoline_pgd during boot to clear the
 identity mappings
 
 - Prevent instrumentation issues resulting from the above changes
