commit 0768f91530ff46683e0b372df14fd79fe8d156e5 upstream.
Some cases in THP like:
- MADV_FREE
- mprotect
- split
mark the PMD non present for temporarily to prevent races. The window for
an L1TF attack in these contexts is very small, but it wants to be fixed
for correctness sake.
Use the proper low level functions for pmd/pud_mknotpresent() to address
this.
