Add test to verify that an architecture understands the semantics correctly.		  
1007 6709 d 5 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now		  
1004 6709 d 16 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling

940 6711 d 22 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6711 d 22 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
934 6712 d 0 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
910 6719 d 3 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
899 6724 d 0 h jermar /kernel/trunk/arch/ ia64 work.

897 6724 d 17 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.
