a=openpgp; fpr=980379BEFEBFBF477EA04EF9C111949073FC0F67 Hi all, This series combined many enhancements for MIPS clocksource subsystems, It improved r4k count synchronisation process, clock source rating for selection, sched_clock eligibility and so on. It seems fixed random RCU stall issue on Loongson 3A4000 multi-node system and some boot failures on QEMU. Please review.
