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"
* tag 'x86-mm-2021-04-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
smp: Micro-optimize smp_call_function_many_cond()

x86/mm/tlb: Remove unnecessary uses of the inline keyword
cpumask: Mark functions as pure
x86/mm/tlb: Do not make is_lazy dirty for no reason
x86/mm/tlb: Privatize cpu_tlbstate
x86/mm/tlb: Flush remote and local TLBs concurrently
x86/mm/tlb: Open-code on_each_cpu_cond_mask() for tlb_is_not_lazy()
