commit 5c2f82deeba84394c621b2d98ce7d73489c88ac3
Author: Luca Dariz <>
Date:   Sun Feb 12 18:28:14 2023 +0100

    use L4 page table directly on x86_64 instead of short-circuiting to pdpbase
    This is a preparation to run the kernel on high addresses, where the
    user vm region and the kernel vm region will use different L3 page
    * i386/intel/pmap.c: on x86_64, retrieve the value of pdpbase from the
      L4 table, and add the pmap_pdp() helper (useful also for PAE).
    * i386/intel/pmap.h: remove pdpbase on x86_64.
