Message:

Add some comments to IA-32 src/boot/boot.S and src/smp.S.

Make the boot stack start on page boundary.
This is required by get_stack_base().

Define 'THE' macro.

Implement preemption_disable() and preemption_enable().

Add memory barrier macros.
IA-32 macros need support for older processors.
Non IA-32 macros are dummy.

Reduction of many #include paths.
