Hello,

kernel test robot noticed a -34.3% regression of vm-scalability.throughput on:


commit: 875fa64577da9bc8e9963ee14fef8433f20653e7 ("mm/hugetlb_vmemmap: fix race with speculative PFN walkers")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master

[still regression on linux-next/master 0b58e108042b0ed28a71cd7edf5175999955b233]

testcase: vm-scalability
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz (Ice Lake) with 256G memory
parameters:

	runtime: 300s
