822 6852 d 13 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.		  
815 6852 d 23 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
814 6852 d 23 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
813 6853 d 12 h jermar /kernel/trunk/ Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.

Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.		  
788 6855 d 18 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
735 6869 d 19 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
701 6881 d 13 h jermar /kernel/trunk/generic/src/mm/ Fix zone_print_one() and zone_print_list().
- add missing spinlock_unlock()
- add missing interrupts_disable() and interrupts_restore()
Coding style fixes and cleanup.		  
686 6883 d 21 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
683 6883 d 21 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
534 6918 d 16 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6918 d 16 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 6918 d 17 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6930 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
490 6937 d 20 h jermar /SPARTAN/trunk/generic/src/mm/ Fix typo and clean up comments.  
489 6937 d 20 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.		  
430 6951 d 14 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
381 6984 d 13 h jermar /SPARTAN/trunk/ Make cross-compiler the default compiler on IA-32.
For native compilations, use ./build.ia32 native.

Small changes elsewhere.		  
379 6985 d 23 h jermar /SPARTAN/trunk/src/mm/ Optimize buddy_system_free().
Remove special-case code from the main codepath.		  
378 6985 d 23 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 6988 d 16 h jermar /SPARTAN/trunk/ Generic buddy allocator.
Please review the code before it is deployed.
