The struct definitions for pdpt, pd, and pt entries has been
removed:
- Bitfield ordering in a struct is implementation dependent,
it can be right-to-left or left-to-right
- The two different structures for page directory entries were
not being used consistently, or when the type of the PDE
was unknown
- Anonymous structs/unions are GCC extensions
Instead these are now u64_t, with bitwise operations used to
get/set fields.
A new set of inline functions for fetcing various page table
structures has been implemented, replacing the older macros.

Take a dummy first argument, so that the BSP entry point (z_x86_prep_c)
has the same signature as the AP entry point (smp_init_top).

Elevate the previously 32-bit-only z_x86_prep_c() function to common
code, so both 32-bit and 64-bit arches now enter the kernel this way.
Minor changes to prep_c.c to make it build with the SMP scheduler on.
