Subject: hw/arm/virt: Remove VirtMachineClass::disallow_affinity_adjustment
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=7f48918a372120a63f18712aa27de5e13b76bbf7;p=thirdparty%2Fqemu.git

hw/arm/virt: Remove VirtMachineClass::disallow_affinity_adjustment

The VirtMachineClass::disallow_affinity_adjustment
field was only used by virt-2.6 machine, which got
removed. Remove it and simplify virt_cpu_mp_affinity().
