Linus Torvalds 14f9643dc9 workqueue: Fixes for v6.5-rc5
Two commits:
 
 * The recently added cpu_intensive auto detection and warning mechanism was
   spuriously triggered on slow CPUs. While not causing serious issues, it's
   still a nuisance and can cause unintended concurrency management
   behaviors. Relax the threshold on machines with lower BogoMIPS. While
   BogoMIPS is not an accurate measure of performance by most measures, we
   don't have to be accurate and it has rough but strong enough correlation.
 
 * A correction in Kconfig help text.

 - The recently added cpu_intensive auto detection and warning mechanism
   was spuriously triggered on slow CPUs.

   While not causing serious issues, it's still a nuisance and can cause
   unintended concurrency management behaviors.

   Relax the threshold on machines with lower BogoMIPS. While BogoMIPS
   is not an accurate measure of performance by most measures, we don't
   have to be accurate and it has rough but strong enough correlation.
