938 6655 d 16 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
937 6655 d 16 h jermar /uspace/trunk/libc/arch/ Switch uspace to ELF init.  
936 6655 d 16 h jermar /boot/trunk/arch/ia64/ ia64 now loads init from ELF. Don't need to do objcopy to binary format.  
935 6655 d 17 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
934 6655 d 17 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code

922 6658 d 12 h jermar /kernel/trunk/genarch/src/mm/ Fix generic page hash table to align down page addresses.
This was the ia64 userspace show stopper.		  
921 6658 d 17 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.		  
920 6658 d 17 h jermar /uspace/trunk/libc/arch/ia64/ Rewrite syscall wrapper in assembly.  
919 6658 d 22 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.		  
918 6658 d 22 h jermar /boot/trunk/ ia64 work.
Changes to make userspace work (boot part).		  
917 6658 d 22 h jermar /uspace/trunk/libc/arch/ia64/ ia64 work.
Changes to make userspace work (uspace part).		  
916 6660 d 23 h jermar /kernel/trunk/arch/ia64/src/ ia64 work.
Support switch from userspace register stack in heavyweight handler.		  
915 6661 d 0 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.		  
914 6661 d 1 h decky /boot/trunk/arch/ppc32/loader/ flush caches  
913 6661 d 2 h decky /boot/trunk/arch/ppc32/loader/ ppc bootstrap almost working  
912 6662 d 14 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.
