205 6876 d 22 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().

177 6878 d 20 h jermar /SPARTAN/trunk/ Add some comments to IA-32 src/boot/boot.S and src/smp.S.

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.		  
176 6879 d 11 h jermar /SPARTAN/trunk/arch/ia32/src/boot/ Initialize the stack prior to using it.  
174 6882 d 11 h jermar /SPARTAN/trunk/ Small changes.

Make 'cli' be the first instruction in boot.S again.		  
170 6886 d 9 h jermar /SPARTAN/trunk/ Add comment to scheduler.c explaining the reason behind saving CPU priority of preempted thread.

Remove two unnecessary cpu_priority_high() calls.		  
168 6887 d 10 h jermar /SPARTAN/trunk/ Add type cast to __address in vm_create().
This seems to fix the problem with userspace.
Looks like KA2PA() returned wrong address when applied on pte_t *.

Uncomment panic() in gp_fault().
Get rid of cli and sti in userspace code.		  
167 6888 d 19 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.		  
149 6912 d 12 h jermar /SPARTAN/trunk/ Fix IA-32's get_memory_size() to return size of memory in bytes instead of in kilobytes.
Some cosmetics in memory map detection.
