Thanks.
"hugetlb: clean up potential spectre issue warnings" was supposed to
fix these.

Are they present in your tree?
When I took a quick look yesterday, those line numbers (4170 and 4172) did not
seem correct. They appeared to be from a version of hugetlb.c without the
above referenced change. However, branch HEAD: cb153b68ff91 does contain the
referenced change. ???
Hi,
Sorry for the inconvenience, this is a known defect in the summary
report, we don't have enough resource to confirm the errors whether
fixed or not in latest branch, so the errors here were discovered
recently, we'll update the description in the report to avoid noise.
Best Regards,
Rong Chen
