switching in SMP mode, use PF_USEDFPU to determine whether a program
used the fpu in the last time quantum and so needs the fpu context
to be saved during context switch.

switch. All other FP programs have ST0_CU1 cleared in their thread_struct,
so that they incur faults on first touching the FPU, and are made the
FPU owner, aka last_task_used_math. used_math determines whether a
thread has used the FPU before; if not, the FPU needs to be initialized
before it can own the FPU. Note: a FP program that has already been
using the fpu (not neccesarily the owner), must reinit the fpu if
it uses the fpu in a signal handler; a sigreturn restores the
original context, discarding the context of the handler.

- IOC3 driver does no longer use GFP_DMA which given the _very_ small
number of available GFP_DMA pages might have deadlocked the system.
- First cut of Origin support. Last minute change: Do no longer use
ARC memory / MD hub memory configuration information but klconfig.h
stuff. Simpler, faster, shorter.
- Zillions of MIPS64 fixes.
