188 6830 d 2 h palkovsky /SPARTAN/trunk/arch/amd64/ AMD64 now can switch into long mode.
Basic page tables working.		  
178 6831 d 3 h palkovsky /SPARTAN/trunk/arch/amd64/ Fixed linker script to include .eh_frame section.
It now boots into protected mode.		  
177 6831 d 5 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 6834 d 20 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.		  
172 6836 d 4 h palkovsky /SPARTAN/trunk/arch/amd64/ Do not allow red area on stack in kernel mode.
Small updates for AMD64 memory layout.		  
169 6839 d 18 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().  
167 6841 d 3 h jermar /SPARTAN/trunk/ Switch over to per vm_t page tables. (breaks ia32 userspace)

Define dummy memcopy() for amd64 and ppc to satisfy compiler.

Get rid of problematic #include <arch/mm/page.h> in mm/page.h.

Indentation fixes and small changes here and there.		  
165 6842 d 21 h palkovsky /SPARTAN/trunk/arch/amd64/boot/ Copied from ia32, bootloader can be the same.  
164 6842 d 21 h palkovsky /SPARTAN/trunk/ Basics for amd64 architecture. It does compile, but it does not work yet.  
4 7022 d 22 h jermar /SPARTAN/trunk/arch/ Added directories for new architectures.
