Subject: [x86/mm] 763802b53a: stress-ng.eventfd.ops_per_sec 11.1% improvement

Greeting,

FYI, we noticed a 11.1% improvement of stress-ng.eventfd.ops_per_sec due to commit:


commit: 763802b53a427ed3cbd419dbba255c414fdd9e7c ("x86/mm: split vmalloc_sync_all()")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

in testcase: stress-ng
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 192G memory
with following parameters:

	nr_threads: 100%
	disk: 1HDD
	testtime: 1s
	class: os
	cpufreq_governor: performance
	ucode: 0x500002c
	fs: ext4






Details are as below:
