request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.
Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.
Hence replace setup_irq() by request_irq().
Changing 'ia64_native_register_percpu_irq' decleration to include
'irq_handler_t' as an argument type in arch/ia64/include/asm/hw_irq.h
was causing build error - 'unknown type name 'irq_handler_t''
This was due to below header file sequence,
+ include/interrupt.h
+ include/hardirq.h
+ asm/hardirq.h
+ include/irq.h
+ asm/hw_irq.h
[ 'ia64_native_register_percpu_irq' declared w/ 'irq_handler_t']
[ 'irq_handler_t' typedef'ed here in 'include/interrupt.h']
'register_percpu_irq' defined to 'ia64_native_register_percpu_irq' is
the one invoked by the caller, not the latter directly. This was done
to support paravirtualization which was removed around 4 years back.
And 'register_percpu_irq' is invoked only inside 'arch/ia64/kernel'.
So 'register_percpu_irq' define to 'ia64_native_register_percpu_irq' is
removed, instead 'ia64_native_register_percpu_irq' is renamed to
'register_precpu_irq()' & it is directly invoked. Also,
'register_precpu_irq()' is declared in a new header file 'irq.h' inside
'arch/ia64/kernel/', this header file is included by C files invoking
'register_percpu_irq()'.
