Hello,

kernel test robot noticed a -16.9% regression of vm-scalability.throughput on:

commit: c9eec08bac96898573c236af9cb0ccee765684fc ("iov_iter: Don't deal with iter->copy_mc in memcpy_from_iter_mc()")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

testcase: vm-scalability
test machine: 224 threads 4 sockets Intel(R) Xeon(R) Platinum 8380H CPU @ 2.90GHz (Cooper Lake) with 192G memory
parameters:

runtime: 300s
size: 256G
test: msync
cpufreq_governor: performance

test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/

If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
