From: Oscar Salvador <osalvador@xxxxxxx>
We provide generic definitions of pXd_leaf in pgtable.h when the arch
do not define their own, where the generic pXd_leaf always return false.
Although x86 defines {pgd,p4d}_leaf, they end up being a no-op, so drop them
and make them fallback to the generic one.
