756	6721 d 6 h	jermar	/kernel/trunk/	Memory management work. Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find(). Page table address is now extracted from the first (i.e. 'as') argument. Add a lot of infrastructure to make the above possible. sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
730	6731 d 12 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727	6733 d 7 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
684	6744 d 15 h	jermar	/kernel/trunk/	Memory management work. Move generic 4-level page table interface to genarch and enable architectures to use different virtual memory mechanisms (e.g. page hash tables). Start page hash table support. Switch ia64 and sparc64 to page hash tables. Other architectures keep on using 4-level page table interface.
646	6765 d 7 h	jermar	/kernel/trunk/	Fix cpu_init(): frame_alloc() can return 0 as the valid address of block of frames. Do not signal error. sparc64 work. Reorganize kernel vs. userspace memory layout. Add panic_printf(). Turn dummy() into nop rather than into infinite loop.
630	6768 d 10 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Register window clean, spill and fill handlers.
627	6768 d 13 h	jermar	/kernel/trunk/	Fix ia64 and sparc64 to compile with new atomic_t. Fix rwlock test #5 and semaphore test #1 to compile with new atomic_t. sparc64 work. TBA must be set before a function call when MMU is switched off.
619	6770 d 4 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Functions for disabling/enabling MMU. TLB initialization. Identity mapping of first 4M for kernel. Switch to kernel copy of trap table.
617	6770 d 7 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Support for TLB Demap operations. Add tlb_invalidate(), tlb_invalidate_asid() and tlb_invalidate_page() (latter two are broken as they ignore asid).
613	6771 d 6 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. More ITLB and DTLB controlling functions.
570	6775 d 7 h	jermar	/kernel/trunk/arch/sparc64/src/mm/	Missing tlb.c from last commit.
538	6778 d 12 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.
534	6779 d 10 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6779 d 10 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6791 d 15 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
426	6814 d 16 h	jermar	/SPARTAN/trunk/	sparc64 work. Add context_save(), context_set() and context_restore(). Remove putchar() definition from ofw.c. Add sparc64 putchar(). Add ppc32 putchar() (i.e. the original ofw.c putchar()). Make arg.h use the builtin va_* constructs.
