Merge cpuidle updates for 6.9-rc1:

 - Prevent the haltpoll cpuidle governor from shrinking guest
   poll_limit_ns below grow_start (Parshuram Sangle).

 - Avoid potential overflow in integer multiplication when computing
   cpuidle state parameters (C Cheng).

 - Adjust MWAIT hint target C-state computation in the ACPI cpuidle
   driver and in intel_idle to return a correct value for C0 (He
   Rongguang).

* pm-cpuidle:
  cpuidle: ACPI/intel: fix MWAIT hint target C-state computation
  cpuidle: Avoid potential overflow in integer multiplication
  cpuidle: haltpoll: do not shrink guest poll_limit_ns below grow_start
