[GIT PULL] erofs fixes for 5.10-rc4

[Gao Xiang <hsiangkao@redhat.com>]

Hi Linus,

Could you consider these 2 bugfixes for 5.10?

A week ago, Vladimir reported an issue that the kernel log
would become polluted if the page allocation debug option is
enabled. I also found this when I cleaned up magical page->mapping
and originally planned to submit these all for 5.11 but it
seems the impact can be noticed so submit the fix in advance.

In addition, nl6720 also reported that atime is empty although
EROFS has the only one on-disk timestamp as a practical
consideration for now but it's better to derive it as what
we did for the other timestamps.

All commits have been tested and have been in linux-next for
almost a week as well. This merges cleanly with master.

Thanks,
Gao Xiang
