Failure of request_irq() for MPC8313 using arch=powerpc

Hello,

I had no problem in using request_irq() for MPC8272 with arch=ppc from Montavista Linux

But I have failure for MPC8313 with arch=powerpc from FreeScale LTIB Linux with error code -38

I found its header file mpc83xx.h under include/asm-ppc, while it's supposed to be under include/asm-powerpc.

I did try to copy the header file to directory asm-powerpc

From MPC8313 datasheet, I have 

GPIO_IRQ = 74

and I use

DEVICE_NAME = "ppc"
IRQ_FLAG = IRQF_SHARED    // use new flag
here my function call

request_irq (GPIO_IRQ,
      ppc_ISR,  
      IRQ_FLAG,
      DEVICE_NAME,   
      NULL);   

I'd appreciate any help on this problem.

Best Regards,

Duy-Kyng
