[Qemu-devel] [PATCH 4/4] hw/arm11mpcore: Fix broken realview_mpcore/arm11mpcore_priv properties

[Peter Maydell]

Fix confusion in the Property arrays for the "arm11mpcore_priv"
(per-CPU devices for the ARM11MPcore CPU) and "realview_mpcore"
(realview-eb board specific device encapsulating CPU and some
extra interrupt controllers) -- the num-irq property was defined
on the wrong device and the mpcore_rirq_properties were defined
as offsets in the wrong structure. The effect was that the
realview-eb-mpcore machine would abort on startup trying to
allocate an insane amount of memory. (This bug was introduced in
the QOM conversion in commit 999e12bb.)
