[Qemu-devel] [RFC PATCH v1 04/13] spapr: Factor out CPU initialization code into realizefn |
Date: |
Thu, 8 Jan 2015 11:40:11 +0530 |
Move some CPU initialization code from machine init function to
CPU realizefn so that it can be used from CPU hotplug path too.
With the inclusion of ppc.h in translate_init.c, explicit *irq_init()
function definitions aren't required, remove them.
