The ci20 port (by kan@) is going to reuse almost all of the intrng code since the SoC in question looks suspiciously like someone took an ARM SoC design and replaced the ARM core with a MIPS core. * migrate out the code; * rename ARM_ -> INTR_; * rename arm_ -> intr_; * move the interrupt flush routine from intr.c / intrng.c into arm/machdep_intr.c - removing the code duplication and removing the ARM specific bits from here. Thanks to the Star Wars: The Force Awakens premiere line for allowing me a couple hours of quiet time to finish the universe builds. Tested: * make universe TODO: * The structure definitions in subr_intr.c still includes machine/intr.h which requires one duplicates all of the intrng definitions in the platform code (which kan has done, and I think we don't have to.) Instead I should break out the generic things (function declarations, common intr structures, etc) into a separate header. * Kan has requested I make the PIC based IPI stuff optional.
