asmlinkage void buserr ( void )

void __init init_IRQ ( void )

The hexagon core comes with a first-level interrupt controller with 32 total possible interrupts. When the core is embedded into different systems/platforms, it is typically wrapped by macro cells that provide one or more second-level interrupt controllers that are cascaded into one or more of the first-level interrupts handled here. The precise wiring of these other irqs varies from platform to platform, and are set up & configured in the platform-specific files.

The first-level interrupt controller is wrapped by the VM, which virtualizes the interrupt controller for us. It provides a very simple, fast & efficient API, and so the fasteoi handler is appropriate for this case.
