source: vbox/trunk/src/VBox/VMM/include/HMInternal.h@ 85854

Last change on this file since 85854 was 85854, checked in by vboxsync, 4 years ago

VMM/HM: Don't need to store fAllowNestedPaging and fAllowUnrestricted (both are unused outside the HM.cpp) in the VM or VMCPU struct.
Makes room for future bools in their place.
