[PATCH v2] arm64: KVM: Register CPU notifiers when the kernel runs at HYP

When the kernel is running at EL2, it doesn't need init_hyp_mode() to configure page tables for HYP. This function also registers the CPU hotplug and lower power notifiers that cause HYP to be re-initialised after the CPU has been reset. To avoid losing the register state that controls stage2

[PATCH] arm64: kvm: 4.6-rc1: Fix VTCR_EL2 VS setting

When we detect support for 16bit VMID in ID_AA64MMFR1, we set the VTCR_EL2_VS field to 1 to make use of 16bit vmids. But, with commit 3a3604bc5eb4 ("arm64: KVM: Switch to C-based stage2 init") this is broken and we corrupt VTCR_EL2:T0SZ instead of updating the VS field. VTCR_EL2_VS was actually
