Hi,

During the review of patch#2, David noticed that we could remove the
!PAGE_ALIGNED handling in remove_pte_table, as we should never get there.
Therefore, let us place that cleanup before the sub-pmd-populated fixup.

More details can be found in the respective changelogs.

  x86/vmemmap: Remove !PAGE_ALIGNED case in remove_pte_table
  x86/vmemmap: Handle unpopulated sub-pmd ranges
