commit 1a893c711a600ab57526619b56e6f6b7be00956e upstream. There is a need for a polling interface for SRCU grace periods. This polling needs to initiate an SRCU grace period without having to queue (and manage) a callback. This commit therefore splits the Tiny SRCU call_srcu() function into callback-queuing and start-grace-period portions, with the latter in a new function named srcu_gp_start_if_needed().
