847 6658 d 16 h jermar /kernel/trunk/arch/sparc64/ Improve comments in start.S.  
846 6658 d 18 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Relocate kernel to 4M.		  
830 6665 d 20 h jermar /kernel/trunk/ Make ASID FIFO for mips32 be allocated statically.
Make ASID FIFO for sparc64 and ia64 be allocated dynamically.
Fix ia64 to call asid_fifo_init().
All three architectures now call asid_fifo_init() from as_arch_init().		  
823 6667 d 11 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
821 6667 d 12 h jermar /kernel/trunk/arch/sparc64/src/mm/ Do not add CONFIG_STACK_SIZE to kernel.size.  
820 6667 d 12 h jermar /kernel/trunk/ Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.		  
815 6667 d 21 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
813 6668 d 10 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.		  
793 6669 d 19 h jermar /kernel/trunk/ Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.		  
792 6669 d 20 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
765 6673 d 13 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6673 d 19 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6673 d 22 h jermar /kernel/trunk/ mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.

Remove GET_PTL0_ADDRESS from kernel.

Update sparc64 comments in barrier.h.		  
758 6674 d 11 h jermar /kernel/trunk/arch/ sparc64 bugfix.
When disabling IMMU and DMMU the kernel has to perform synchronization operation
(e.g flush %r or membar #Sync instruction). There is no guarantee that the address
contained in %r is in DTLB and therefore the flush instruction can fault. Normally
this would be recognized and fixed by the OpenFirmware Fast Data MMU fault handler.
However, this handler lives in virtually mapped memory and an attempt to execute
there while the MMUs are disabled would result in a nested trap leading to error state.
Replacing flush %r instruction with membar #Sync, wich is sufficient in this case,
fixes this problem.		  
757 6674 d 14 h jermar /kernel/trunk/ Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator.
This area contains VGA text frame buffer and should be avoided.
falloc2 test now passes on ia64.		  
756 6675 d 10 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.		  
753 6676 d 18 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
747 6680 d 12 h jermar /kernel/trunk/ ia64 work.
Add nice wrappers for thash and ttag instructions.
Add nice wrappers for accessing reion registers and PTA.
Fix set_vhpt_environment().
Allocate and initialize page_ht (a.k.a. VHPT).

Add missing header to sparc64.
Remove excessive header from debug.h.		  
746 6680 d 20 h jermar /kernel/trunk/ Page hash table modifications.  
743 6682 d 13 h jermar /kernel/trunk/arch/ sparc64 work.
13 bits wide means the max value is 8191 and not 0x8191.
