[Qemu-devel] [PATCH v3 1/3] exec: split cpu_exec_init()

[Laurent Vivier <lvivier@redhat.com>]

Put in cpu_exec_initfn() what initializes the CPU,
and let in cpu_exec_init() what adds it to the environment.

As cpu_exec_initfn() is called by all XX_cpu_initfn() call it
directly in cpu_common_initfn().
cpu_exec_init() is now a realize function, it will be renamed
to cpu_exec_realizefn() and moved to the XX_cpu_realizefn()
function in a following patch.
