From: Marc Zyngier <maz@kernel.org> In subsequent patches we'll allow an FIQ handler to be registered, and FIQ exceptions will need to be triaged very similarly to IRQ exceptions. So that we can reuse the existing logic, this patch factors the IRQ triage logic out into macros that can be reused for FIQ. The macros are named to follow the elX_foo_handler scheme used by the C exception handlers. For consistency with other top-level exception handlers, the kernel_entry/kernel_exit logic is not moved into the macros. As FIQ will use a different C handler, this handler name is provided as an argument to the macros. There should be no functional change as a result of this patch.
