Subject: [PATCH 7/7] KVM: arm64: Fix stale VGICv3 comments in the nVHE world switch
Date: Tue, 15 Sep 2026 13:38:46 +0100	[thread overview]
Message-ID: <20260915123846.2317931-8-fuad.tabba@linux.dev> (raw)
In-Reply-To: <20260915123846.2317931-1-fuad.tabba@linux.dev>

__hyp_vgic_save_state() and __hyp_vgic_restore_state() handle GICv5 as
well as GICv3, but their comments name VGICv3 only.
