Integrator/CP regression after QOM'ification of integratorcp.c
The following command line no longer works (i.e. the guest does not boot) with QEMU 2.7.0:
qemu-system-arm -M integratorcp -m 128M -kernel HelenOS-0.6.0-arm32-integratorcp.boot
The HelenOS image can be downloaded here:
http://www.helenos.org/releases/HelenOS-0.6.0-arm32-integratorcp.boot
I did git bisect and came to this revision:
a1f42e0c9abc1028a8bb8686dbb3749fcd2d18e8 is the first bad commit

Upon closer inspection, I discovered that for some reason s->memsz in integratorcm_init() is zero. In the last good revision, this value was 128. As a temporary workaround, hardcoding it to this expected value fixes the problem.
