      async: Asynchronous function calls to speed up kernel boot · 22a9d645
      Arjan van de Ven 提交于
      Right now, most of the kernel boot is strictly synchronous, such that
      various hardware delays are done sequentially.
      
      In order to make the kernel boot faster, this patch introduces
      infrastructure to allow doing some of the initialization steps
      asynchronously, which will hide significant portions of the hardware delays
      in practice.
      
      In order to not change device order and other similar observables, this
      patch does NOT do full parallel initialization.
      
      Rather, it operates more in the way an out of order CPU does; the work may
      be done out of order and asynchronous, but the observable effects
      (instruction retiring for the CPU) are still done in the original sequence.
