912 6830 d 4 h jermar /kernel/trunk/ ia64 work.

ivt.S:
Detect userspace stack in heavyweight handler and switch to kernel stack.
Remember the old stack pointer.
As for register stack, kernel stack is assumed still.
Fix alignment issues that showed when STACK_ITEMS was odd.
Fix ld8 instruction that did subtraction of 8 instead of addition of 8.

scheduler.c:
Change before_thread_runs_arch() to calculate address of top of the stack
for the interrupt handler.		  
534 6921 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6921 d 5 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6933 d 9 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
472 6946 d 10 h jermar /SPARTAN/trunk/ Changes in build system.
For .S targets, always do -D__ASM__.
Remove unnecessary #define __ASM__ from various *.S files.
At the end of build, generate disassembler dump for kernel.raw.

ia64 work.
Better General Exception handler.		  
470 6946 d 23 h jermar /SPARTAN/trunk/ ia64 work.
Big cleanup of IA-64 interrupt processing.
Merge of interrupt.c and interrupt_handler.c.
Rewrite of ivt.S and interrupt.c.
Higher level interrupt handlers are now passed a vector number and a pointer to stack structure.

ia32 work.
ia32 has ordered writes. Until it deploys weaker memory ordering model, write_barrier() can be empty statement.		  
435 6950 d 3 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Begin implemention of heavyweight interrupt handler.
Finish implementation of interval timer.
Add some PAL macros.		  
433 6952 d 3 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Fix definition of __u32.
Add more register manipulation functions.
Add unions describing bit-structured registers.
Distinguish between timer, unhandled and spurious external interrupts.
Initialize interval timer to generate first timer interrupt.		  
431 6952 d 12 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Exclude external interrupt from universal_handler() scope.		  
35 7138 d 14 h jermar /SPARTAN/trunk/ Early support for IA-64 architecture.
