Subject: [PATCH v2 00/13] Core RCU patches for 6.4

Hello,

These are core RCU patches for 6.4. I am resending as there are few more
patches for MAINTAINERS file changes, and few more tags. Plus I dropped the
Frederick's patch that Thomas took in for fixing the entry code.

o  MAINTAINERS files additions and changes.

o  Fix hotplug warning in nohz code.

o  Tick dependency changes by Zqiang.

o  Lazy-RCU shrinker fixes by Zqiang.

o  rcu-tasks stall reporting improvements by Neeraj.

o  Other changes.

Let me know if any objections to anything.

thanks,

 - Joel
