Hi Chintan, Do you have any issue in my patchset? If so, can you please comment on them? It complicates the thing when you send a different approach without telling why a different approach is needed. Your approach purges TLB after updating pmd/pud, which I think is broken. Can you work on top of my patchset and properly implement pXd_free_pte_page() for arm64? I will send out my v2 today. Thanks, -Toshi
