1246 6640 d 4 h vana /kernel/trunk/arch/ia32/src/smp/ This patch enables 32 base of GDT on APs at boot. It should now be able to use GDTs allocated up of 16MB so I hope this patches AP crash bug ocurred in some memory configurations.  
1242 6640 d 23 h jermar /kernel/trunk/arch/ This time really fix wrong definition of K_DATA_START.

532 6784 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6796 d 6 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
458 6810 d 8 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
406 6836 d 23 h jermar /SPARTAN/trunk/arch/ Fix directives for K_TEXT_START, K_TEXT_START_2 and K_DATA_START sections to be more descriptive about section's content.

Remove __fake from amd64 pm.c.

298 6874 d 8 h decky /SPARTAN/trunk/ remove lower 2 GB identity mapping (IA-32)  
291 6875 d 1 h jermar /SPARTAN/trunk/arch/ia32/src/smp/ AP cpus are not supposed to touch A20 for this bit is enabled by the BSP cpu.  
279 6875 d 22 h decky /SPARTAN/trunk/arch/ia32/ GRUB basic booting (IA-32)  
267 6876 d 5 h decky /SPARTAN/trunk/arch/ia32/ proper way of initializing GDT during boot on IA-32, fixes the nasty hack
SMP might be still broken		  
232 6878 d 5 h jermar /SPARTAN/trunk/arch/ia32/src/ Fix addresses in GDT and IDT to be virtual addresses.  
177 6881 d 9 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.		  
117 6957 d 5 h jermar /SPARTAN/trunk/ Do panic() on page_fault().
Good for long testing in SMP mode as silent "extinctions" of a CPU are no longer supported.

Tiny changes here and there.		  
113 6964 d 20 h jermar /SPARTAN/trunk/ SMP recovery patch #2 (SMP is no longer broken !!!).
Fix missing KA2PA() operation in ap.S which was causing page faults during AP early initialization.
Fix bug in map_page_to_frame(): 'root' was interpretted as kernel address while read_dba() returns physical address.
Make references to page directory and page tables use kernel addresses instead of physical addresses.

Massive frame allocation code cleanup.
Basically revert to what we had had before implementation of userspace.

Usual cosmetics.
