Subject: [PATCH 0/7] MIPS: clocksource cumulative enhancements

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.

Thanks
