It's weird. They don't turn up on linux-mm either, and that's running
at kvack.org, also majordomo. They don't get through when sent with
either heirloom-mailx or with sylpheed.
Also, it seems that when Anshuman originally sent the patch, linux-mm
and linux-kernel didn't send it back out. So perhaps a spam filter
triggered?
I'm seeing
https://lore.kernel.org/linux-arm-kernel/1615278790-18053-3-git-send-email-anshuman.khandual@xxxxxxx/
which is via linux-arm-kernel@xxxxxxxxxxxxxxxxxxx but the linux-kernel
server massacred that patch series. Searching
https://lkml.org/lkml/2021/3/9 for "anshuman" only shows 3 of the 7
email series.
One of the emails (as sent my me) is attached, if that helps.

Subject: mm: generalize SYS_SUPPORTS_HUGETLBFS (rename as ARCH_SUPPORTS_HUGETLBFS)
SYS_SUPPORTS_HUGETLBFS config has duplicate definitions on platforms that
subscribe it. Instead, just make it a generic option which can be
selected on applicable platforms. Also rename it as
ARCH_SUPPORTS_HUGETLBFS instead. This reduces code duplication and makes
it cleaner.
