Hi folks,
I've been meaning to run RCU torture under v5.13-rt1 to validate my hacking around the RCU offloaded state [1], but have hit some warnings.
The second patch clearly isn't a thing of beauty, but FWIW it lets me run RCU torture tests without any extra steps.
As mentioned over IRC, this started as a .setup() callback for the kosftirqd threads gated behind CONFIG_RCU_BOOST && CONFIG_RCU_TORTURE_TEST, but I figured keeping RCU torture specific stuff within rcutorture.c would be a tad smarter. I hate either version, but here it is regardless.

Cheers, Valentin
