    rcu: Settle config for userspace extended quiescent state · 2b1d5024
    Frederic Weisbecker authored
    Create a new config option under the RCU menu that put
    CPUs under RCU extended quiescent state (as in dynticks
    idle mode) when they run in userspace. This require
    some contribution from architectures to hook into kernel
    and userspace boundaries.
