958 6811 d 6 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.		  
955 6811 d 6 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
947 6811 d 16 h vana /kernel/trunk/ Better purge page selection.  
945 6812 d 5 h vana /kernel/trunk/arch/ia64/  
944 6812 d 5 h vana /kernel/trunk/ Itanium tlb_invalidate_pages  
940 6812 d 7 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6812 d 8 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
935 6812 d 8 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
928 6812 d 13 h vana /kernel/trunk/ Itanium tlb_invalidate_all  
923 6813 d 1 h vana /kernel/trunk/arch/ia64/src/ paging_start counting fix on ia64  
921 6815 d 8 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.		  
919 6815 d 13 h jermar /kernel/trunk/ ia64 work.
Changes to make userspace work (kernel part).
Use ski.conf from contrib directory to run Ski.

There is actually no appropriate syscall handler yet.		  
916 6817 d 15 h jermar /kernel/trunk/arch/ia64/src/ ia64 work.
Support switch from userspace register stack in heavyweight handler.		  
915 6817 d 16 h jermar /kernel/trunk/arch/ia64/ ia64 work.
- Another item had to be allocated on stack to remember new value written to ar.bspstore.
Fix heavyweight interruption handler to calculate RSC.loadrs from the new value of ar.bspstore
instead from the old one.
Uncomment instructions switching ar.bspstore.
- Configure kernel with 512M of memory.		  
912 6819 d 6 h jermar /kernel/trunk/ ia64 work.

ivt.S:
Detect userspace stack in heavyweight handler and switch to kernel stack.
Remember the old stack pointer.
As for register stack, kernel stack is assumed still.
Fix alignment issues that showed when STACK_ITEMS was odd.
Fix ld8 instruction that did subtraction of 8 instead of addition of 8.

scheduler.c:
Change before_thread_runs_arch() to calculate address of top of the stack
for the interrupt handler.		  
911 6819 d 10 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.)		  
910 6819 d 13 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
904 6822 d 7 h jermar /kernel/trunk/arch/ia64/src/mm/ ia64 fix in page.c
== (comparison) was used istead of = (assignment).		  
903 6822 d 8 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 6823 d 13 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.
