541 6909 d 21 h jermar /kernel/trunk/generic/src/mm/ Get rid of junk.  
539 6910 d 1 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes.
- Add some comments.
- Update zone information on frames allocation/deallocation.		  
538 6910 d 2 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes II.
- Rewrite IS_BUDDY_LEFT_BLOCK so that it does not need floating point on some architectures (e.g. IA-64).
- Get rid of IS_BUDDY_RIGHT_BLOCK.
- Make sparc64 use zone_create_in_region.		  
537 6910 d 3 h jermar /kernel/trunk/ Buddy system cleanup and fixes.
- missing use of KA2PA in frame_init
- truncating black list addresses to frame boundaries
- removal of left-over obsolete structures
- fixing some comments		  
536 6910 d 23 h bondari /kernel/trunk/ Minor bugfix caused by invalid frame_region_not_free() usage  
534 6911 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6911 d 1 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)		  
532 6911 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6923 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
489 6930 d 4 h jermar /SPARTAN/trunk/generic/ Make the buddy system more general.
Store implementation defined pointer in buddy_system_t.
Pass buddy system pointer to implementation defined buddy system operations.		  
488 6930 d 10 h bondari /SPARTAN/trunk/generic/src/mm/ Small fix :)  
487 6930 d 10 h bondari /SPARTAN/trunk/generic/src/mm/ Frame isect/coalesce functions optimization  
480 6933 d 0 h bondari /SPARTAN/trunk/generic/ Buddy system allocator implementation. Not checked. For review only.  
479 6934 d 1 h bondari /SPARTAN/trunk/generic/ Buddy system implementation. Not functional yet - only framework prepeared.
Also added 2 macros FRAME2ADDR and ADDR2FRAME.		  
430 6943 d 22 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
413 6958 d 21 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.		  
375 6981 d 4 h jermar /SPARTAN/trunk/src/mm/ Replace free() call with early_free() call in zone_create().  
374 6982 d 21 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 6983 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.		  
368 6985 d 7 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
