534 6744 d 18 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6744 d 18 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 6744 d 19 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
524 6750 d 0 h jermar /kernel/trunk/generic/include/ sort.h was actually written by Sergey Bondari.  
518 6752 d 15 h jermar /kernel/trunk/ Improve kconsole's support for recognition of commands with arguments.
Implement ARG_TYPE_STRING.
Add 'describe' command.
Move kconsole.c to generic/src/console.
Move kconsole.h to generic/include/console.		  
517 6753 d 15 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.		  
511 6756 d 14 h jermar /kernel/trunk/ Enable dummy kconsole for ia32 and amd64 (UP mode works).  
510 6756 d 14 h jermar /kernel/trunk/ Add chardev_t.
This type is meant to abstract any input character device such as keyboard, serial port etc.
Add stdin.
Add dummy kconsole.		  
503 6756 d 22 h jermar /kernel/trunk/ Rename arch_late_init() to arch_pre_smp_init().
Add arch_post_smp_init().
Enable IRQ_KBD on ia-32 (doesn't work on Bochs SMP, works on Bochs UP).		  
501 6756 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6757 d 16 h jermar /SPARTAN/trunk/ Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find().
New names should make it more apparent that these two belong together.		  
489 6763 d 22 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.		  
483 6764 d 18 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.		  
482 6765 d 19 h jermar /SPARTAN/trunk/generic/include/ Fix typo in buddy.h.
Make default memsize 8M.		  
480 6766 d 18 h bondari /SPARTAN/trunk/generic/ Buddy system allocator implementation. Not checked. For review only.
