[Qemu-devel] [PATCH qom-cpu] qemu-common.h: Make qemu_init_vcpu() stub static inline

[Andreas Färber]

Turn the *-user macro into a no-op inline function to avoid
unused-variable warnings and band-aiding #ifdef'ery.

This allows to drop an #ifdef for alpha and avoids more for unicore32
and other upcoming trivial realizefn implementations.
