111 6936 d 16 h palkovsky /SPARTAN/trunk/ Code cleanup in scheduler.c thread.c - removed unnecessary spinlock.
atomic_inc, atomic_dec moved to arch/atomic.h instead of arch/smp/atomic.h,
advisable to use even in non-smp mode.
Fixed atomic_inc, atomic_dec in mips architecture.		  
73 6962 d 14 h vana /SPARTAN/trunk/ Finished FPU lazy context switching - first version. I have not tested it and there are many things which must be changed when
it runs first time OK.		  
57 6965 d 12 h vana /SPARTAN/trunk/ Begin support for FPU context switching on platforms which can't do it in lazy way.  
56 6965 d 13 h vana /SPARTAN/trunk/ Added fpu_context.h arch dep files and removed struct fpu_context from context.h files  
52 6965 d 14 h vana /SPARTAN/trunk/ Move fpu_context switching functions from context.s to fpu_context.c on all platforms.
Add fpu_context.h.

Make before_thread_runs() arch-independent and create arch dependent version before_thread_runs_arch().		  
46 6965 d 22 h vana /SPARTAN/trunk/ Remove fpu_context pointer from context_t.
Add fpu_context statically to thread_t.
Two functions for saving and restoring FPU context on lazy switch.
