MIPS: IPI Improvements
|
expand
|
Hi all, This series improved general handling to MIPS IPI interrupts, made IPI numbers scalable, and switch to IPI-MUX for all GERNERIC_IPI users on mux. It is a prerequisite for enabling IRQ_WORK for MIPS. It has been tested on MIPS Boston I6500, malta CoreFPGA3 47K MT/ interAptiv MPF, Loongson-2K, Cavium CN7130 (EdgeRouter 4), and an unannounced interaptiv UP MT platform with EIC. I don't really know broadcom platforms and SGI platforms well so changes to those platforms are kept minimal (no functional change). Please review.
