This series converts all generic page table entries direct derefences via
pxdp_get() based helpers extending the changes brought in via the commit
c33c794828f2 ("mm: ptep_get() conversion"). First it does some platform
specific changes for m68k and x86 architecture.

This series has been build tested on multiple architecture such as x86,
arm64, powerpc, powerpc64le, riscv, and m68k etc.
