r254466 increased the KVA from 512GB to 2TB which requires 4 PDP pages as opposed to a single one before the change. This broke minidumpsys() since it assumed that the entire KVA could be addressed via a single PDP page. Fix this by obtaining the address of the PDP page from the PML4 entry associated with the KVA being dumped. Reported by: pho Submitted by: kib Pointy hat to: neel
