Description
```
Description: The ARM and Cortex-M3 interrupt handlers restores all registers
upon return. This could be improved as well: If there is no
context switch, then the static registers need not be restored
because they will not be modified by the called C code.
(see arch/renesas/src/sh1/sh1_vector.S for example)
