442 6779 d 3 h vana /SPARTAN/trunk/arch/ia64/src/ sp should not be decremented after last save  
441 6779 d 4 h jermar /SPARTAN/trunk/arch/ia64/src/ r12 (stack pointer) must be descremented prior to storing data into new memory stack frame.  
439 6779 d 23 h jermar /SPARTAN/trunk/arch/ia64/src/ Two small ia64 improvements.  
438 6780 d 0 h jermar /SPARTAN/trunk/arch/ia64/src/ ia64 work.
Heavyweight handler should be complete up to the point where it switches back to interrupted RSE context.		  
435 6780 d 19 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Begin implemention of heavyweight interrupt handler.
Finish implementation of interval timer.
Add some PAL macros.		  
434 6782 d 18 h jermar /SPARTAN/trunk/arch/ia64/src/ Fix switch variable.  
433 6782 d 18 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.		  
432 6782 d 20 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Add some asm functions for manipulation with PSR, AR and CR registers.		  
431 6783 d 4 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Exclude external interrupt from universal_handler() scope.		  
430 6784 d 18 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
416 6798 d 2 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Put RSE into lazy mode before writing ar.bspstore and ar.rnat.
Flush RSE before setting ar.bspstore so that ar.bsp is set to the same address.		  
415 6798 d 3 h jermar /SPARTAN/trunk/arch/ia64/include/ Make context_set() reset ar.pfs.pfm (especially ar.pfs.pfm.sol) so that register stack does not underflow.  
414 6799 d 6 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.		  
413 6799 d 16 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.		  
412 6800 d 7 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
context_save() doesn't have to restore ar.pfs as it is a leaf procedure.
Get rid of assembler warning for start.S.		  
403 6806 d 20 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
402 6807 d 5 h jermar /SPARTAN/trunk/ Add ALIGN() macro.

Fix usage of early_mapping() in main.c.
The previous version would not map part of the heap.
Please, review.		  
391 6812 d 18 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.		  
389 6813 d 5 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().		  
388 6814 d 3 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Map interrupt vectors to their names.
