12649	BMI2 cpuid feature mistakenly enabled in VM	Wim Heirman		"When running VirtualBox on a Haswell i5-3427U, the BMI2 cpuid feature bit is turned on in the VM while it is off on the host. Applications running in the VM therefore think the CPU supports instructions such as SHLX, which it doesn't, and generate illegal instruction traps.

CPU: Intel(R) Core(TM) i5-3427U CPU @ 1.80GHz[[BR]]
Host: Windows 8[[BR]]
VM: Ubuntu 13.10
