Aneesh Kumar K.V 392b466981 powerpc/mm: add DEBUG_VM WARN for pmd_clear 
Patch series "mm/debug_vm_pgtable fixes", v4.

This patch series includes fixes for debug_vm_pgtable test code so that
they follow page table updates rules correctly.  The first two patches
introduce changes w.r.t ppc64.

Hugetlb test is disabled on ppc64 because that needs larger change to satisfy
page table update rules.

These tests are broken w.r.t page table update rules and results in kernel
crash as below.

This patch (of 13):

With the hash page table, the kernel should not use pmd_clear for clearing
huge pte entries.  Add a DEBUG_VM WARN to catch the wrong usage.
