Merge tag 'x86-mm-2021-04-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 tlb updates from Ingo Molnar:
"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"
