pcluster should be only set up for all managed pages instead of
temporary pages. Since it currently uses page->mapping to identify,
the impact is minor for now.

Fixes: 5ddcee1f3a1c ("erofs: get rid of __stagingpage_alloc helper")

Thanks, I've also added a note to the commit message like this,
"
[ Update: Vladimir reported the kernel log becomes polluted
   because PAGE_FLAGS_CHECK_AT_FREE flag(s) set if the page
   allocation debug option is enabled. ]
"
Will apply all of this to -fixes branch.

Thanks for noticing that, looks fine to me.

Thanks,
