History
Linus Torvalds 635de956a7 The x86 MM changes in this cycle were: 
- Implement concurrent TLB flushes, which overlaps the local TLB flush with the
    remote TLB flush. In testing this improved sysbench performance measurably by
    a couple of percentage points, especially if TLB-heavy security mitigations
    are active.
 
  - Further micro-optimizations to improve the performance of TLB flushes.
