    Subject: [PATCH] x86, mm: make pgd next calculation consistent with pud/pmd

    Just like the way we calculate next for pud and pmd, aka
    round down and add size.

    also remove not needed next checking, just pass end with phys_pud_init.

    pyhs_pud_init() uses PTRS_PER_PUD to stop its loop early so it could handle
    big end properly.
