    kernel - Increase ACPI_SEMAPHORES_MAX_PENDING
    
    * Increase ACPI_SEMAPHORES_MAX_PENDING to a very large number.
      Some of the ACPI codes assumes that mutexes always succeed,
      but the mutex code uses the semaphore code and the semaphore
      code appears to have an arbitrary failure path based on the
      number of concurrent requests.
    
    * This fixes kernel confusion and console spam from the ACPI
      subsystem when running sysctl -a concurrently on more than
      4 threads.
