Subject: rcu: Wire up rcu_end_inkernel_boot()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=967dcb8fe6a9a75be346400539261e0416baf370;p=linux-beck.git

rcu: Wire up rcu_end_inkernel_boot()

This commit adds the invocation of rcu_end_inkernel_boot() just before
init is invoked.  This allows the CONFIG_RCU_EXPEDITE_BOOT Kconfig
option to do something useful and prepares for the upcoming
rcupdate.rcu_normal_after_boot kernel parameter.
