379 6821 d 7 h jermar /SPARTAN/trunk/src/mm/ Optimize buddy_system_free().
Remove special-case code from the main codepath.		  
378 6821 d 8 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 6824 d 0 h jermar /SPARTAN/trunk/ Generic buddy allocator.
Please review the code before it is deployed.		  
376 6824 d 4 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!		  
375 6824 d 4 h jermar /SPARTAN/trunk/src/mm/ Replace free() call with early_free() call in zone_create().  
374 6825 d 22 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 6826 d 0 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 6828 d 1 h jermar /SPARTAN/trunk/src/main/ The more physical frames, the more memory allocated for heap.  
368 6828 d 7 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
367 6828 d 22 h jermar /SPARTAN/trunk/ Physical memory management work.
Implement zone_*() and some frame_*() functions.		  
364 6829 d 11 h palkovsky /SPARTAN/trunk/ Added support for msim with 4kc instructions.
Fixed support for upstream msim.

Small boot fix on Indy.		  
360 6830 d 7 h jermar /SPARTAN/trunk/ Compilation fixes.
memcpy() must be declared in memstr.h		  
351 6833 d 10 h jermar /SPARTAN/trunk/src/lib/ Ok. The idea of _qsort() was not broken at all.
Revert the changes and make _qsort() call _qsort() rather than qsort() so that the idea has effect.
Add _bubblesort() to optimize number of allocations when bubblesort algorithm is invoked from _qsort().
Add doxygen-style comments.		  
350 6833 d 23 h jermar /SPARTAN/trunk/src/ Remove _qsort() as its concept is fundamentally broken.

Move lib/the.c to proc/the.c.		  
349 6834 d 0 h jermar /SPARTAN/trunk/ Optimize sorting functions so that malloc() and free() is called only for e_size > EBUFSIZE.
Smaller buffers are allocated directly on the stack.

Some copyright holder fixes on some files written by Ondrej Palkovsky.		  
341 6837 d 7 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
338 6838 d 5 h jermar /SPARTAN/trunk/ Avoid code duplication by creating generic byteorder.h.
Some naming changes in swap functions.		  
336 6838 d 7 h bondari /SPARTAN/trunk/src/lib/ minor  
335 6838 d 7 h bondari /SPARTAN/trunk/src/lib/ More effective memory allocations with help of qsort wrapper method  
333 6838 d 8 h bondari /SPARTAN/trunk/src/lib/ Copyright notice and proper tabs
