rcu: Fixup noinstr warnings (2020-06-25 08:24:32 -0700)
----------------------------------------------------------------
Paul E. McKenney says:
A single commit that uses "arch_" atomic operations to avoid the
instrumentation that comes with the non-"arch_" versions. In preparation
for that commit, it also has another commit that makes these "arch_"
atomic operations available to generic code.
Without these commits, KCSAN uses can see pointless errors.
Both from Peter Zijlstra.
