Hi,all
     I've patched the kernel 3.5.7 with xenomai,and xenomai have been 
enabled. After that, I want to have a  normal gpio interrupt test with 
normal way using request_irq, found its return value is -/EINVAL,
Finally found that IRQ_NOREQUEST was set in the irq_desc[irq_number] 
through debug. could you give me some advice? thanks.
         the following was the irq_desc of irq_gpio:

         [   66.087719] irq 10, desc: c1805600, depth: 0, count: 0, 
unhandled: 0
         [   66.097903] ->handle_irq():  c0065678, 
__ipipe_chained_irq+0x0/0x4
         [   66.104157] ->irq_data.chip(): c052de50, 
pxa_internal_irq_chip+0x0/0x70
         [   66.110751] ->action():   (null)
         [   66.114010]    IRQ_NOPROBE set
         [   66.117039]  IRQ_NOREQUEST set
         [   66.120063]   IRQ_NOTHREAD set

Thank you very much~
