        src/sys/arch/arm/arm: cpufunc_asm_armv7.S
        src/sys/arch/arm/arm32: genassym.cf irq_dispatch.S
        src/sys/arch/arm/include/arm32: frame.h

Log Message:
Implement a "fast" path for IRQ handling out of the idle loop.  Since we
are in SVC32 already we only need to save a few registers.  Processing is
also simplified since we know we can't return to user-mode.
