From: Colin Cross <ccross@xxxxxxxxxxx> The pointers to the 2nd level page tables are converted to 1st level page table entries, which means kmemleak can't find them and assumes they have been leaked. Call kmemleak_ignore on the 2nd level page tables to prevent them from showing up in kmemleak reports.
