rcu: Remove the now-obsolete PROVE_RCU_REPEATEDLY Kconfig option
The PROVE_RCU_REPEATEDLY Kconfig option was initially added due to the volume of messages from PROVE_RCU: Doing just one per boot would have required excessive numbers of boots to locate them all. However, PROVE_RCU messages are now relatively rare, so there is no longer any reason to need more than one such message per boot. This commit therefore removes the PROVE_RCU_REPEATEDLY Kconfig option. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Cc: Ingo Molnar <mingo@kernel.org>
