the interrupt framework is also going to be used by another (MIPS) architecture. IPI implementations may vary much across different architectures. An IPI implementation should still define INTR_IPI_COUNT and use intr_ipi_setup_counters() to setup IPI counters which are inside of intrcnt[] and intrnames[] arrays. Those are used for sysctl and ddb. Then, intr_ipi_increment_count() should be used to increment obtained counter. Reviewed by: imp Differential Revision: https://reviews.freebsd.org/D5459
