[x86/mm/tlb] 2f4305b19f: will-it-scale.per_thread_ops 23.3% improvement

by kernel test robot

Greeting, FYI, we noticed a 23.3% improvement of will-it-scale.per_thread_ops due to commit: commit: 2f4305b19fe6a2a261d76c21856c5598f7d878fe ("x86/mm/tlb: Privatize cpu_tlbstate") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: will-it-scale on test machine: 144 threads 4 sockets Intel(R) Xeon(R) CPU E7-8890 v3 @ 2.50GHz with 512G memory with following parameters: nr_task: 100% mode: thread test: tlb_flush3 cpufreq_governor: performance ucode: 0x16 test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two. test-url: https://github.com/antonblanchard/will-it-scale Details are as below:
