Struct Pdpte1G 

#[repr(transparent)]
pub struct Pdpte1G(u64);

L3 PDPTE (1 GiB leaf) — maps a single 1 GiB page (PS = 1).

• PAT (Page Attribute Table) selector lives at bit 12 in this form.
• Physical address uses bits 51:30 and must be 1 GiB aligned.
• Dirty is set by CPU on first write; Global keeps TLB entries across CR3 reload unless explicitly invalidated.

This is a terminal mapping (leaf).
