Message:

Documentation updates for amd64, mips32 and ia32.

Replace %L with %P printf() formatter in MPS and ACPI detection functions to print addresses in maximal width.

Tweak memmap.S and IA-32 and AMd64 boot.S.
Cancel unneeded instructions.
Replace cmpl $0, %ebx with testl %ebx, %ebx.
Move memmap.S data to K_DATA_START section.

    4 The fifth port, amd64 port, is heavily based on ia32 port.
    5 It was originally written by Ondrej Palkovsky.
    6 The goal is to support AMD64 or Intel Extended Memory PC's.
    7 The new 64-bit code makes use of portable parts of ia32.
