forked from Imagelibrary/rtems

* cpu_asm.S: Fixed exception return address, modified FP context switch so FPU is properly enabled and also doesn't screw up the exception FP handling. * idtcpu.h: Added C0_TAR, the MIPS target address register used for returning from exceptions. * iregdef.h: Added R_TAR to the stack frame so the target address can be saved on a per-exception basis. The new entry is past the end of the frame gdb cares about, so doesn't affect gdb or cpu.h stuff. * rtems/score/cpu.h: added an #ifdef so cpu_asm.S can include it to obtain FPU defines without systax errors generated by the C defintions. * cpu.c: Improved interrupt level saves & restores.
