 PMD split lock enabling requires pgtable_pmd_page_ctor() call on PMD table
 allocation and pgtable_pmd_page_dtor() on freeing.
 
-Allocation usually happens in pmd_alloc_one(), freeing in pmd_free(), but
-make sure you cover all PMD table allocation / freeing paths: i.e X86_PAE
-preallocate few PMDs on pgd_alloc().

 With everything in place you can set CONFIG_ARCH_ENABLE_SPLIT_PMD_PTLOCK.
