2020-06-24 Thread Marc Zyngier
For as long as SMP ARM has existed, IPIs have been handled as something special. The arch code and the interrupt controller exchange a couple of hooks (one to generate an IPI, another to handle it). Although this is perfectly manageable, it prevents the use of features that we could use if IPIs we
