177 6846 d 1 h jermar /SPARTAN/trunk/ 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.		  
173 6849 d 16 h jermar /SPARTAN/trunk/ 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.		  
139 6885 d 20 h cejka /SPARTAN/trunk/arch/ia32/ Added e801 method for obtaining memory size, improved e820 method for memory map.  
115 6926 d 13 h jermar /SPARTAN/trunk/ Implement several assembler functions in gcc's __asm__ notation instead of in .s or .S file.
Gain both better speed and size.		  
38 6963 d 18 h jermar /SPARTAN/trunk/arch/ia32/ Make read/write_dr0() inlined.  
28 6972 d 0 h jermar /SPARTAN/trunk/ Small improvements.  
27 6972 d 14 h jermar /SPARTAN/trunk/ APIC changes and fixes.
Be more robust during MP configuration.

Do not use APIC ID as CPU_ID_ARCH anymore.
Changing APIC ID's is not a good idea.
Use dr0 register instead.		  
11 7030 d 13 h jermar /SPARTAN/trunk/ Clean up (ia32 vs. i386).
Header files reorganization.		  
1 7037 d 19 h jermar /SPARTAN/ Initial import
