Hi,
This is an updated version of page_is_secretmem() changes.
This is based on v5.12-rc7-mmots-2021-04-15-16-28.
@Andrew, please let me know if you'd like me to rebase it differently or
resend the entire set.
v3:
* add missing put_compound_head() if we are to return NULL from
gup_page_range(), thanks David.
* add unlikely() to test for page_is_secretmem.
v2:
* move the check for secretmem page in gup_pte_range after we get a
reference to the page, per Matthew.
