commit f4268786ee453a18659b7fde00efd821fc83cb09 Author: Aaron Durbin adurbin@chromium.org Date: Fri Apr 29 23:15:12 2016 -0500
cpu/x86/mp_init: remove unused callback arguments
The BSP and AP callback declarations both had an optional argument that could be passed. In pratice that functionality was never used so drop it.
