[v2,25/44] printk: Remove trace_.*_rcuidle() usage

Commit Message

Peter Zijlstra Sept. 19, 2022, 10 a.m. UTC

The problem, per commit fc98c3c8c9dc ("printk: use rcuidle console
tracepoint"), was printk usage from the cpuidle path where RCU was
already disabled.

Per the patches earlier in this series, this is no longer the case.
