757 6685 d 15 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 6686 d 11 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 6687 d 19 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
751 6687 d 21 h jermar /kernel/trunk/arch/ia64/ Fix initialization of pta.base on ia64.  
749 6689 d 19 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.  
748 6690 d 19 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6691 d 13 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 6691 d 21 h jermar /kernel/trunk/ Page hash table modifications.  
744 6692 d 15 h jermar /kernel/trunk/arch/ia64/ Remove ia64 boot as it is not needed by the simulator.  
742 6693 d 14 h jermar /kernel/trunk/arch/ sparc64 work.
Memory context (ASID) is, in fact, 13 bits (and not 12 bits) wide.		  
741 6693 d 15 h jermar /kernel/trunk/ Unlock address space prior TLB shootdown in get_asid() to unify
the locking order among mips32, sparc64 and ia64.

Add ASID_STEALING_ENABLED macro to disable the stealing part on ia64
in a clean way.		  
740 6693 d 21 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
736 6695 d 18 h jermar /kernel/trunk/arch/ia64/src/ Fix panic_printf on ia64 to call halt() instead of cpu_halt().  
730 6696 d 18 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
728 6698 d 13 h vana /kernel/trunk/arch/ia64/src/mm/ Serialize writes to RR because of assembler RAW warning.  
727 6698 d 13 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
726 6698 d 13 h jermar /kernel/trunk/arch/ia64/src/mm/ Temporarily disable set_VHPT_environment() to stop ia64 kernel from faulting.  
716 6702 d 17 h vana /kernel/trunk/arch/ia64/src/mm/ ttag and thash envelope functions  
715 6702 d 17 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions  
710 6702 d 20 h vana /kernel/trunk/arch/ia64/include/mm/ VHPT entry
