Function inter_processor_call 

pub fn inter_processor_call(targets: &CpuSet, call_fn: fn()) -> PendingIpis

Executes a function on other processors.

The provided function call_fn will be executed on all target processors specified by targets. It can also be executed on the current processor. The function should be short and non-blocking, as it will be executed in interrupt context with interrupts disabled.

The function call_fn will be executed asynchronously on the target processors. However, if called on the current processor, it will be synchronous.

The returned PendingIpis can be used to wait until all remote target processors have handled IPIs for this call.

Panics

This function will panic if a hardware error occurs while sending an IPI to a remote processor.
