systemd-journal-flush.service failed due to a timeout resulting in a very very
slow boot on my test laptop. qemu test on openqa failed due to the same problem.

https://openqa.qa.codethink.co.uk/tests/365

A bisect showed the problem to be 8615ff6dd1ac ("mm: filemap: check if THP has
hwpoisoned subpage for PMD page fault"). Reverting it on top of 5.10.79-rc1
fixed the problem.
Incidentally, I was having similar problem with Linus's tree
for last few days and was failing since 20211106 (did not get the time to check).
I will test mainline again with this commit reverted.
