Linus Torvalds 4ca4256453 Merge branch 'core-rcu.2021.08.28a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu
Pull RCU updates from Paul McKenney:
 "RCU changes for this cycle were:

   - Documentation updates

   - Miscellaneous fixes

   - Offloaded-callbacks updates

   - Updates to the nolibc library

   - Tasks-RCU updates

   - In-kernel torture-test updates

   - Torture-test scripting, perhaps most notably the pinning of
     torture-test guest OSes so as to force differences in memory
     latency. For example, in a two-socket system, a four-CPU guest OS
     will have one pair of its CPUs pinned to threads in a single core
     on one socket and the other pair pinned to threads in a single core
     on the other socket. This approach proved able to force race
     conditions that earlier testing missed. Some of these race
     conditions are still being tracked down"
