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.

Preparations for weaker preemption model.
Make all kernel stacks (i.e. startup, scheduler and thread) be STACK_SIZE bytes long.
Reincarnate "the" structure. This time, it is planned to be located at the base of each and every kernel stack.
On IA-32 and MIPS, implement get_stack_base() functions. On the rest of supported platforms, define it to be dummy.

Make rwlock test #3 compile again.
Make rwlock test #4 preemption-safe.
Prepare for preemption controlling functions.

Replace the deadlock-prone TLB shootdown algorithm with a deadlock-free implementation.
The implementation is a variant of the CMU TLB consistency algorithm.
Very inefficient implementation of a very inefficient (but correct) algorithm.

Switch from mm-based 'the' mechanism to macro-based 'cpu_private_data[CPU_ID_ARCH]' mechanism.
Added l_apic_id() and some other minor APIC changes.
Move gdtr to K_DATA_START section.
Move K_DATA_START section immediately behind K_TEXT_START section so that real-mode addresses work even with growing size of kernel code.
