[PATCH v2 01/16] ARM: Make global handler and CONFIG_MULTI_IRQ_HANDLER mutually exclusive

[Tony Lindgren]

* Marc Zyngier <marc.zyngier at arm.com> [110926 03:30]:
> Even when CONFIG_MULTI_IRQ_HANDLER is selected, the core code
> requires the arch_irq_handler_default macro to be defined as
> a fallback.
> 
> It turns out nobody is using that particular feature as both PXA
> and shmobile have all their machine descriptors populated with
> the interrupt handler, leaving unused code (or empty macros) in
> their entry-macro.S file just to be able to compile entry-armv.S.
> 
> Make CONFIG_MULTI_IRQ_HANDLER exclusive wrt arch_irq_handler_default,
> which allows to remove one test from the hot path. Also cleanup both
> PXA and shmobile entry-macro.S.
