  x86/CPU/AMD: Prevent reset reasons from being retained across reboot (2025-10-15 21:38:06 +0200)

----------------------------------------------------------------
- Reset the why-the-system-rebooted register on AMD to avoid stale bits
  remaining from previous boots

- Add a missing barrier in the TLB flushing code to prevent erroneously not
  flushing a TLB generation

- Make sure cpa_flush() does not overshoot when computing the end range of
  a flush region

- Fix resctrl bandwidth counting on AMD systems when the amount of monitoring
  groups created exceeds the number the hardware can track
