[1/2] KVM: arm64: Make nVHE ASLR conditional on RANDOMIZE_BASE commit: 24f69c0fa4e252f706884114b7d6353aa07678b5 [2/2] KVM: arm64: Substitute RANDOMIZE_BASE for HARDEN_EL2_VECTORS commit: a59a2edbbba7397fede86e40a3da17e5beebf98b Cheers, M. -- Without deviation from the norm, progress is not possible.
