Jiaxun Yang (7):
  MIPS: sync-r4k: Rework to be many cores firendly
  MIPS: time: Use CPUHUP to handle r4k timer
  MIPS: Kconfig: Always select SYNC_R4K if both SMP and r4k timer is
    enabled
  MIPS: Loongson64: Remove custom count sync procudure
  MIPS: cevt-r4k: Don't handle IRQ if clockevent is not enabled
  MIPS: cevt-r4k: Enable intimer for Loongson CPUs with extimer
  MIPS: KVM: Don't use htimer when INTIMER is disabled
