911 6640 d 14 h jermar /kernel/trunk/arch/ia64/ ia64 work.

Change heavyweight interrupt handler to use bank 0 registers instead of AR.KR0 and AR.KR1.
This prevents userspace from the possibility to see what addresses are being used by kernel.

Store kernel stack address in bank 0 r23 instead of AR.KR7. Again, userspace will not be
able to read the address of its kernel stack.

Increase FRAME_SIZE to 64K as this is the first supported page size in which will fit
thread's combined register and memory stack. (RSE can write out as many as 16K.)		  
904 6643 d 11 h jermar /kernel/trunk/arch/ia64/src/mm/ ia64 fix in page.c
== (comparison) was used istead of = (assignment).		  
903 6643 d 12 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Add code needed for running multiple address spaces and location of kernel stack
after switch from userspace.		  
902 6644 d 17 h jermar /kernel/trunk/ ia64 work.
More capable TLB miss handlers.
The ia64 kernel now passes mm/mapping1 test.

Fix generic hash table to properly initialize lists.

Change page_ht() to properly initialize inserted PTE's.
Change format of generic page hash table PTE's.		  
901 6644 d 19 h jermar /kernel/trunk/arch/ ia64 work.
Provide PA2KA(identity) mapping for kernel data references via Alternate Data TLB Fault handler.
Add before_thread_runs_arch() that maps kstack, if necessary.
Add easy to use dtlb_mapping_insert() for comfortable insertion of kernel data mappings.		  
900 6645 d 12 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Proper TLB fault handlers' headers and prototypes.
PFN 0 needs no longer be marked unavailable to frame allocator.		  
899 6645 d 13 h jermar /kernel/trunk/arch/ ia64 work.
Add dummy TLB fault handlers.
Improve code reuse in arch/mm/tlb.c.		  
897 6646 d 6 h jermar /kernel/trunk/ sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse.		  
893 6646 d 18 h jermar /kernel/trunk/arch/ sparc64 work.
Revive OFW console code and use it before the kernel switches to standalone console.

ia32 + ia64 cosmetic changes.		  
892 6647 d 14 h vana /kernel/trunk/ Itanium active keyboard  
879 6648 d 11 h vana /kernel/trunk/arch/ia64/ Itanium kernel page extended to maximum (256M) repaired RR manipulation functions, paging setuping function and added some comments.  
872 6651 d 6 h vana /kernel/trunk/ Init stack base fix
Removing commented code		  
870 6651 d 6 h vana /kernel/trunk/arch/ia64/ Removed forgoten debug function and reverted my mistake  
869 6651 d 7 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
840 6658 d 17 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
830 6663 d 16 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 6665 d 7 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
819 6665 d 10 h vana /kernel/trunk/arch/ia64/ TR tlb filling functions  
818 6665 d 13 h vana /kernel/trunk/arch/ia64/ IA-64 TLB filling functions for dynamic tlb filling (TC tlb).  
816 6665 d 16 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.
