391 6798 d 4 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 6798 d 14 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().		  
387 6800 d 8 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for condvar.c.  
386 6800 d 8 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for mutex.c.  
385 6800 d 9 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for rwlock.c.  
384 6800 d 10 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for semaphore.c.  
383 6800 d 11 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for spinlock.c.  
382 6801 d 3 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for waitq.c.  
381 6803 d 3 h jermar /SPARTAN/trunk/ Make cross-compiler the default compiler on IA-32.
For native compilations, use ./build.ia32 native.

Small changes elsewhere.		  
379 6804 d 12 h jermar /SPARTAN/trunk/src/mm/ Optimize buddy_system_free().
Remove special-case code from the main codepath.		  
378 6804 d 13 h jermar /SPARTAN/trunk/ Redeclare eraly_malloc() with __attribute__ ((malloc)) to improve optimizations.

Reorganize #include's in scheduler.c.

Buddy system improvements.
Make buddy_system_free() explicitly invalidate order of blocks before they are coalesced.
Add some assertions.		  
377 6807 d 6 h jermar /SPARTAN/trunk/ Generic buddy allocator.
Please review the code before it is deployed.		  
376 6807 d 9 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!		  
375 6807 d 9 h jermar /SPARTAN/trunk/src/mm/ Replace free() call with early_free() call in zone_create().  
374 6809 d 3 h jermar /SPARTAN/trunk/ Revert previous change in frame_t as it broke IA-64.
(Most likely some alignment problem.)

Rename heap_init(), malloc() and free(), respectively, to early_heap_init(), early_malloc() and early_free(), respectively.
Define new macros malloc() and free(). They are to be replaced by real functions some day.		  
373 6809 d 5 h jermar /SPARTAN/trunk/ Physical memory management work.
Add "__attribute__ ((packed))" to frame_t so that it takes up less space.
Note that this is essential as there is lot of these structures.
Remove busy list from zone_t as it is redundant.		  
369 6811 d 6 h jermar /SPARTAN/trunk/src/main/ The more physical frames, the more memory allocated for heap.  
368 6811 d 12 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
367 6812 d 3 h jermar /SPARTAN/trunk/ Physical memory management work.
Implement zone_*() and some frame_*() functions.		  
364 6812 d 16 h palkovsky /SPARTAN/trunk/ Added support for msim with 4kc instructions.
Fixed support for upstream msim.

Small boot fix on Indy.
