[PATCH] KVM: arm64: Simplify __kvm_timer_set_cntvoff implementation

Now that this function isn't constrained by the 32bit PCS, let's simplify it by taking a single 64bit offset instead of two 32bit parameters. Signed-off-by: Marc Zyngier --- arch/arm64/include/asm/kvm_asm.h | 2 +- virt/kvm/arm/arch_timer.c| 12 +--- virt/kvm/arm/hyp/timer-sr.c

[PATCH] KVM: arm64: Move virt/kvm/arm to arch/arm64

Now that the 32bit KVM/arm host is a distant memory, let's move the whole of the KVM/arm64 code into the arm64 tree. As they said in the song: Welcome Home (Sanitarium). Signed-off-by: Marc Zyngier --- MAINTAINERS | 1 - arch/arm64/kvm/Makefile

[PATCH] KVM: arm64: Use cpus_have_final_cap for has_vhe()

By the time we start using the has_vhe() helper, we have long discovered whether we are running VHE or not. It thus makes sense to use cpus_have_final_cap() instead of cpus_have_const_cap(), which leads to a small text size reduction. Signed-off-by: Marc Zyngier ---

[PATCH V2] arm64/cpufeature: Drop open encodings while extracting parange

Currently there are multiple instances of parange feature width mask open encodings while fetching it's value. Even the width mask value (0x7) itself is not accurate. It should be (0xf) per ID_AA64MMFR0_EL1.PARange[3:0] as in ARM ARM (0487F.a). Replace them with
