The patch titled
mm: __tlb_remove_page() check the correct batch
has been removed from the -mm tree. Its filename was

Subject: mm: __tlb_remove_page() check the correct batch
From: Shaohua Li <shaohua.li@xxxxxxxxx>
__tlb_remove_page() switches to a new batch page, but still checks space
in the old batch. This check always fails, and causes a forced tlb flush.
