Mark Rutland 81d27c6ed6 KVM: arm/arm64: vgic: fix possible spectre-v1 in vgic_mmio_read_apr() ... [ Upstream commit 5e1ca5e23b ] It's possible for userspace to control n. Sanitize n when using it as an array index. Note that while it appears that n must be bound to the interval [0,3] due to the way it is extracted from addr, we cannot guarantee that compiler transformations (and/or future refactoring) will ensure this is the case, and given this is a slow path it's better to always perform the masking.
