Boot and suspend/resume should not be slowed down in kernels built with
CONFIG_RCU_LAZY=y. In particular, suspend can sometimes fail in such
kernels.
This commit therefore adds rcu_async_hurry(), rcu_async_relax(), and
rcu_async_should_hurry() functions that track whether or not either
a boot or a suspend/resume operation is in progress. This will
enable a later commit to refrain from laziness during those times.
Export rcu_async_should_hurry(), rcu_async_hurry(), and rcu_async_relax()
for later use by rcutorture.
